Social Infrastructure Social and Industrial Systems 4-in-1 Traction Inverter for PMSMs in Practical Use Social Infrastructure 2-set type 1-set type 4-in-1 VVVF inverters Social and Industrial Systems The size and weight of variable-voltage variablefrequency (VVVF) inverters have been considered a major obstacle to their widespread uptake for electric multiple units (EMUs) because a single VVVF inverter can drive only one motor. Therefore, induction motor (IM) systems, which can drive multiple motors, have been commonly used in EMUs instead of VVVF inverters. To address this situation, Toshiba has developed a 4-in-1 VVVF inverter capable of driving up to four high-efficiency totally enclosed permanent-magnet synchronous motors (PMSMs). Our 4-in-1 VVVF inverter requires approximately the same vehicle space as a conventional IM drive system to drive the same number of motors, making it an ideal choice as a replacement for IM drive systems. The use of a VVVF inverter with totally enclosed PMSMs provides significant benefits, including a reduction in traction power consumption(*1) and an increase in regenerative electric power due to a higher load on regenerative braking(*2). Consequently, the overall power consumption of the EMU is reduced. PMSMs We have delivered a unit consisting of two 4-in-1 VVVF inverters (referred as “2-set type” in the figure), which can drive eight PMSMs, for the 8000 series EMUs of Keio Corporation, as well as a unit consisting of one 4-in-1 VVVF inverter (“1-set type” in the figure), which can drive four PMSMs, for the 8000 series EMUs of Hankyu Corporation. Actual measurements made by Hankyu Corporation show an approximately 10% reduction in traction power consumption and an approximately 85% increase in regenerative power, resulting in an approximately 50% reduction in overall energy consumption. We have already received several orders and inquiries for the newly developed VVVF inverters and will continue to promote them as environmentally friendly systems.

We have delivered electrical equipment for use in the mass-produced N700A cars. In addition to equipment already supplied for the N700 series, the N700A incorporates our new innovations such as a cruise controller that accurately maintains 34 Traction converter for N700A Central monitoring equipment constant vehicle speed, and a traction converter that is 15% lighter than the predecessor type used in the N700. Our technologies have contributed to the realization of the advanced N700A design philosophy; namely, safety, reliability, riding comfort, and environmental friendliness. Major Equipment for Korail Class 8500 Electric Locomotive Prototype EH800 AC electric locomotive Korail Class 8500 electric locomotive (8501) Construction of a new railway station provisionally named Shin-Hakodate is being planned so that the Hokkaido Shinkansen, which runs at 25 kV AC, and the Kaikyo Line, which runs at 20 kV AC, can share tracks over part of the route. In response, Toshiba has developed, in cooperation with Japan Freight Railway Company, a prototype of the EH800 AC electric locomotive that can be electrified at both 25 kV AC and 20 kV AC. An L-shaped guide for derailment prevention, as well as axle temperature sensors and vibration sensors, have been adopted in this new model. The EH800 is also equipped with a digital automatic train control (ATC) system called the digital communication & control for Shinkansen-ATC (DS-ATC) system, which will continue to be used as the automatic train control-locomotive (ATC-L) system for the time being, as well as digital wireless radio devices. These technologies have already been proven in past Shinkansen projects. Korea Railroad Corporation (Korail) has replaced its older electric locomotives with the new 8500 series. Toshiba supplied major equipment for the new locomotives to Hyundai Rotem Company, the manufacturer of the 8500 series, including the main transformers, power conversion cubicles (propulsion inverters and auxiliary power supply inverters), traction motors, wheelsets, and cooling blowers. The six-axle locomotive has six traction motors all working together to generate a power output of 6 600 kW. Consequently, a single 8500 series locomotive can haul heavy loads that previously required two conventional locomotives. The traction inverters drive the traction motors axle by axle to provide high wheel-rail adhesion and a high level of redundancy. The locomotive is designed to operate at up to 150 km/h for rapid transit, despite the use of a nose-suspension drive. To achieve this design target, the “unsprung mass,” or the weight of the motor supported through the axle, was reduced by reducing the weight of the driving gear unit and the traction motor itself. The 8500 series has been in commercial service since July 2012. 35 Social Infrastructure Social and Industrial Systems EH800 AC Electric Locomotive for Japan Freight Railway Company Electrical Equipment for EMU800 Series and Tilting Trains of Taiwan Railways Administration Social and Industrial Systems Dysprosium-Free High-IronConcentration Sm-Co Magnet for Motors Traction motors for hybrid and electric vehicles, railway cars, and industrial equipment operate at relatively high temperatures, and heat-resistant neodymium magnets containing dysprosium are generally used in these applications. Current sources of dysprosium are limited, however, and recent supply restrictions and price rises have led to rising global concern over future shortages. Against this background, Toshiba has developed a highperformance dysprosium-free magnet that provides a strong magnetic force at operating temperatures of 100°C or higher. We increased the amount of iron (Fe) in the magnet from 15% to between 20 and 25% by weight, and used heat-treatment technology such as optimization of the temperature, time, and pressure at the time of combustion to reduce the oxide as well as the phase with high copper concentration in the magnet, both of which inhibit magnetic force. The increased iron concentration Oxide Void Oxide Cu-rich phase Main converter EMU800 series train improved the remanent magnetization and enabled us to create a samarium-cobalt (Sm-Co) magnet with superior magnetic properties to those of heat-resistant neodymium magnets at typical motor operating temperatures. We have verified the performance of motors containing the new magnet with 20% iron by weight, and confirmed that they have almost the same capabilities and size as motors containing a heat-resistant neodymium magnet. The new magnet is highly suited to motors that must combine high heat resistance with high performance and small size when installed in automobiles, railway cars, machine tools, and elevators. Part of this development work was supported by the Rare Metal Substitute Materials Development Project of Japan’s New Energy and Industrial Technology Development Organization (NEDO). Nd-Dy-Fe-B magnet (*) Remanent magnetization Social Infrastructure Toshiba has supplied sets of electrical equipment (main transformer, main converter, traction motor, auxiliary power unit, and train control monitoring system) to the Taiwan Railways Administration (TRA) for 296 cars of EMU800 series trains as well as 136 cars of tilting trains for the Tze-Chiang Limited Express. Since both trains are of the 25 kV AC type, the design of the hardware has been standardized as much as possible, while differences in specifications such as acceleration performance and the presence of tilting systems are handled by software. This allows standardization of spare parts and enables TRA to reduce its operating costs. The tilting trains have been running on the Tze-Chiang Limited Express service since February 2013, and the EMU800 series trains were commissioned in August 2013.

The SCiBTM battery cell is incorporated as one of the key components supporting the “ENE-CHARGE” technology required for the vehicle’s regenerative braking system, which is at the core of the “SUZUKI GREEN Technology” that was named RJC Technology of the Year in 2013. This high-power type SCiBTM battery cell offers about 6 000 W/L regeneration power density per volume at room temperature and about 1 400 W/L regeneration power density per volume at low temperature (-10°C). The battery thus has high input power characteristics, particularly in low-temperature regions, allowing it to be charged at a much higher current than any other battery. Taking advantage of this sophisticated regeneration power density, the New Wagon R can execute the “idling stop” function for a longer time than conventional cars because TM battery cell Specification 62 × 96 × 13 mm (including terminals) 150±5 g Approx. 6 000 W/L SOC: state of charge some of the electrical component systems are supplied with the charged power while the car is stopped. The New Wagon R also achieves a fuel efficiency of 28.8 km/L (JC08 mode), one of the highest fuel efficiency levels in its class. In order to address issues related to efficiency requirements in 2020, Toshiba forecasts that vehicles equipped with the idling stop system will show a much higher rate of growth in the market than electric vehicles (EVs) and hybrid electric vehicles (HEVs) because they are more practical and less expensive than HEVs and EVs. As part of our continuous efforts to build a strong presence in this market, we are working toward development and production of the next-generation highpower type SCiBTM and focusing further on the in-vehicle system market. RJC: Automotive Researchers’ & Journalists’ Conference of Japan Mass Production of Motors and Inverters for HEVs and PHEVs Toshiba has been supplying motors and inverters for HEVs and plug-in HEVs (PHEVs) to Ford Motor Company since the first half of 2012. For this purpose, a mass production line for automotive inverters was inaugurated at Toshiba’s Mie Works. In addition, a line for the mass production of automotive motors was constructed at Toshiba International Corporation, U.S.A. This is our first overseas facility for automotive motor production. We will further reinforce our supply system in order to meet the expanding demand for environmentally friendly cars such as HEVs and PHEVs in the U.S. car market.

Optimization of the control loops to further reduce energy costs is one of the most important issues in this field. As part of the lineup of the Unified Controller nv seriesTM, Toshiba has developed a model-driven-PID(*) (MD-PID) that provides a superior control function block compared with conventional PID systems, as well as the nv-ADCOP advanced process control optimizer. The main features of the MD-PID are as follows: · excellent control over processes with a long dead time · adjustment of setpoint tracking performance and external disturbance suppression · excellent control over various process dynamic characteristics. The main features of the nv-ADCOP are as follows: · System identification: Samples real-time process data from the nv series controller to calculate process parameters. · Control optimization: Simulates feedback and feedforward control using the calculated process parameters and determines the optimal parameters for each controller. · Performance evaluation: Evaluates the performance of feedback and feedforward control executed by the nv series controller. The nv-ADCOP comes with a function block library containing the MD-PID. The new product makes it possible to not only improve existing PID control loops but also realize more efficient feedback and feedforward control than conventional PID systems.

With the recent improvement of control equipment performance, demand for high-speed, massprocessing industrial computers has been increasing. In response to this demand, we have developed the FA2100SS model 500 slim type industrial computer, the first model in the industry to incorporate the thirdgeneration Intel® CoreTM i7 processor. The processing speed of the central processing unit (CPU) has been improved by approximately four times compared with the previous model. The new model also has the latest high-speed interfaces including USB 3.0 and PCI Express® 3.0, and provides high-performance onboard graphics functions to realize high-speed processing of mass data. Moreover, features such as reliability, availability, and serviceability (RAS) functions, easy maintenance, and long-term support, which are essential for industrial computers, are inherited from the conventional models. The new product will contribute to stable long-term operations in the social infrastructure field. Intel and Intel Core are trademarks of Intel Corporation in the United States and other countries.

In addition to the automation of banknote processing through the dissemination of automated teller machines (ATMs) in developed countries, the remarkable economic growth of emerging countries has increased demand for banknote processing equipment. This trend requires products with a fast processing speed, compact footprint, and expandability of the system. The IBS-1000 offers flexibility and expandability based on a modularity concept, the highest level of processing speed of machines in this class(*), and innovative compact online strapping modules. As a result, mixeddenomination notes can be automatically counted, sorted, authenticated, and strapped—all in a single pass—thus improving the efficiency of operations. Through an alliance with a Korean manufacturer to outsource all of the material procurement and manufacturing, we have also achieved a competitive price to target not only developed markets but also emerging markets where demand is increasing. (*) As of February 2013 (as researched by Toshiba) Toshiba is the first Japanese manufacturer to have developed a dual-interface (contact and contactless) integrated circuit (IC) module that supports Visa payWave, the contactless payment solution that Visa Inc. introduced in Japan in the spring of 2013. There is growing demand for contactless payment solutions that allow customers to make small payment transactions simply by waving a card or smartphone in front of a terminal. Visa Inc. developed Visa payWave to meet this need, and it has proved to be popular in the United States, Europe, and Asia as it offers fast and easy payment at convenience stores, gas stations, and other merchants. We have considerable expertise in wireless near-field communication (NFC), including the development of a similar IC module for MasterCard® PayPassTM cards, and have been selected as the initial supplier of dualinterface IC modules for Visa payWave in Japan. We are providing the new IC module, the FSΣ21 series, to the card vendor. This latest module processes transactions 30% faster than our earlier version and supports both contact and contactless transactions for credit, debit, and prepaid cards. Like the Visa payWave solution, the module is compatible with the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) 14443 and NFC standards for contactless communications at close proximity and can be integrated into cards from other companies. We will use our advanced technology and product lineup to promote further contactless payment solutions in Japan and overseas.

We have now developed a new flash memory playout server called ON-AIR MAX FLASHTM for overseas markets, incorporating functions that are required by broadcast stations in other countries. ON-AIR MAX FLASHTM provides a high level of performance such as the world’s fastest level of file transfer speed (829 Mbit/s)(*), the capability of playing 40 channels simultaneously, and a quick playout response time of three frames from command. It also offers high reliability with a 10-year memory lifetime warranty based on our original wear-leveling technique, data protection by forward error correction (FEC), and other features. Among the unique functions for overseas customers incorporated into the ON-AIR MAX FLASHTM are a control graphical user interface (GUI), automatic frame description (AFD), redundant array of independent (inexpensive) disks (RAID), and closed caption conversion. It also has a significantly improved response time of variable speed playout (trick play). We are introducing this playout server to broadcast stations and system integrators in the United States and Europe. (*) As of April 2013 (as researched by Toshiba) GT-Series UHF Digital TV Transmitter Liquid-cooled high-power model Air-cooled low-power model GT-Series digital TV transmitters Toshiba has developed the GT-Series ultrahighfrequency (UHF) digital TV transmitters as new globalstandard models that support multiple digital broadcasting standards throughout the world with a smaller footprint and lower price than previous models. 40 A platform design has been adopted for the units inside the power amplifier (PA), which amplifies the broadcasting signal, to allow their common use in both the liquid-cooled and air-cooled models. Moreover, the liquid-cooled PA has been downsized and lightened through the use of a cold plate designed with a new, thin structure. The liquid-cooled model achieves up to 9 kW power output per rack. The GT-Series transmitters can be configured to support multiple digital broadcasting standards in different countries simply by changing the software program. We exhibited three models of the GT-Series—the aircooled low-power (200 W), air-cooled medium-power (1 kW), and liquid-cooled high-power (3 kW) models—at the National Association of Broadcasters (NAB) Show (Las Vegas) in April 2012, BroadcastAsia (Singapore) in June, and the International Broadcasting Convention (IBC) (Amsterdam) in September of the same year. The GT-Series transmitters were supplied to the first customer in September 2012. We are promoting them worldwide, particularly in emerging countries where digital TV broadcasting services will start. 2.4 m direction while varying its elevation angle for 3D observation. The new radar has 128 slotted array antennas and applies a digital beam forming (DBF) technique to simultaneously form multiple vertical beams for Newly developed phasedan elevation coverage of 0 to 90 array antenna degrees. As a result, it can observe weather within a radius of 60 km and at altitudes up to 14 km while rotating the antenna horizontally only once, and the time required for this observation is shortened to only 10 to 30 seconds. These results were achieved under a commissioned research project of NICT entitled “Research and development of next-generation Doppler radar technology.” Phased-array radar Observation of cumulonimbus clouds using conventional radar and phased-array radar Toshiba has developed a new phased-array weather radar for high-speed three-dimensional (3D) meteorological observations with high spatial resolution in cooperation with the National Institute of Information and Communications Technology (NICT), Japan and Osaka University. In recent years, there have been many disasters caused by severe localized weather events such as sudden downpours and lightning as well as tornadoes. The major cause of such weather events is cumulonimbus clouds, which grow rapidly in a short time of about 10 to 30 minutes. Therefore, a weather radar system must complete high-speed 3D observations at a high altitude within one minute in order to precisely grasp the life cycle of cumulonimbus clouds. It usually takes about five minutes for a conventional weather radar system to rotate its parabolic antenna 10 times or more in the azimuth X-Band 25 W-Class Small-Package Power Amplifier Module Solid-state power amplifiers (SSPAs) used for satellite communication systems and radar systems must have high output power as well as high gain. Since these SSPAs require numerous components, small-package power X-band 25 W-class smallpackage power amplifier module amplifier components with high gain and high efficiency have been awaited to reduce the size and power consumption of SSPAs. Observation result (overhead view from the sky over Osaka Bay) Example of 3D weather observation using phased-array radar For this purpose, Toshiba has developed the TGM9398-25 25 W-class small-package power amplifier module for use in the X band (8-12 GHz). This module contains a two-stage amplifier, each stage of which incorporates a different gallium nitride (GaN) high electron mobility transistor (HEMT) amplifier chip, and bias circuitry in a package that is the same size as that of ordinary one-stage amplifier devices through layout optimization design. The newly developed amplifier module achieves excellent performance with a gain of more than 20 dB, whereas conventional 25 W-class GaN HEMT devices have a much lower 9 dB gain. Furthermore, it also achieves a high power-added efficiency of more than 35%. With a new lineup of 25 W-class small-package amplifier modules, compact, high-efficiency SSPAs will become readily available. 41 Social Infrastructure Conventional radar Social and Industrial Systems 2.5 m Phased-Array Weather Radar Setouchi Height Monitoring Unit the differences between the actual altitude of the aircraft measured by the HMU and the flight level based on the barometric altimeter of the aircraft. The Setouchi HMU thus makes monitoring possible to verify compliance with the reduced vertical separation minimum (RVSM), which reduces the vertical separation between aircraft flying at high altitude from 2 000 feet (609.6 m) to 1 000 feet (304.8 m). The HMU is expected to assist in meeting the growing demand for aircraft transportation and improving airspace safety. Social Infrastructure Toshiba has developed the Setouchi Height Monitoring Unit (HMU) and installed it on the shores of the Seto Inland Sea. This is the first HMU in Japan(*), allowing aircraft altitudes to be precisely measured by ground equipment. The Setouchi HMU calculates an aircraft’s altitude by using the differences in time of arrival of radio frequency (RF) signals transmitted from the aircraft after five ground stations placed around the Seto Inland Sea have received these signals. This HMU realizes precise measurement with a standard error of only 25 feet (7.62 m) or less.

Reduction of power consumption is a critical issue for UV irradiation equipment, however, because its lamps must be constantly lit. Dimming control technology, which 42 controls the power consumption of the lamps according to the quality and quantity of the treated water, is an effective means of achieving this goal. Generally, flowmeters are necessary for dimming control according to the water quantity and UV transmittance (UVT) meters are necessary for dimming control according to the water quality. Since UVT meters are expensive and require daily maintenance, the installation of UVT meters gives rise to the new problem of increases in the initial cost and maintenance costs. UV irradiation equipment usually has UV intensity sensors (UV sensors), which monitor the lamps to check that they are lit normally. Toshiba has developed UV irradiation equipment based on the principle that the measured intensity is related to the UVT of the water between the lamps and the UV sensors. Our UV irradiation equipment thus realizes dimming control compatible with UVT fluctuations without the need for UVT meters if the UV sensors are installed at the proper distance from the lamps. The newly developed equipment can reduce both the initial cost and running costs normally required for additional UVT meters.

In many offices, the cooling load from office automation (OA) equipment in winter and the requirements for air conditioning differ in individual zones even on the same floor, depending on the effect of solar radiation. The SHRM-i system responds more effectively to such requirements in larger buildings compared with past models. Its maximum system power has been increased from 85.0 kW (30 hp) to 120.0 kW (42 hp), realizing the coexistence of energy saving and a comfortable environment by simultaneous cooling and heating operation. The SHRM-i system achieves efficient simultaneous cooling and heating operation through the adoption of DC twin-rotary compressors designed for high efficiency in the medium-capacity range, vector-controlled inverters to control rotation speed in 0.1 Hz increments, low-speed rotation control of large outdoor fans, and flex-variable refrigerant flow control. By applying these exhaustheat-recovery technologies, the SHRM-i reduces power consumption. Moreover, the SHRM-i system permits a greater maximum piping length of up to 200 m and height differences between indoor units of up to 40 m, ensuring industry-leading flexibility in air-conditioning system design. hp: horsepower 44 MiNi-SMMSTM outdoor unit Toshiba Carrier Corporation has developed the MiNiSMMSTM energy-efficient side-blow type outdoor unit for multi-split air-conditioning systems targeting office and luxury condominium projects in the Chinese market, and launched newly developed 33.5 kW (12 hp) and 28.0 kW (10 hp) models in October 2012. By the adoption of a new large-capacity DC twin-rotary compressor with improved efficiency in the medium-load range and new large propeller fans, this product achieves a large capacity and an integrated part load value (IPLV) rating of 5.85, the best among side-blow systems in the industry(*) as certified by the China Energy Label of the China National Institute of Standardization, as well as significantly reduced running cost. For easier installation, the footprint of the unit has been downsized by 50% compared with conventional top-blow systems so that the unit can be easily fitted on the balcony of each floor of a condominium, and its weight has also been reduced by about 33% compared with conventional top-blow systems. Furthermore, this outdoor unit consists of a threepiece chassis that can be divided, allowing it to be readily applied to compact models.
