Dalam sistem tenaga listrik, terdapat penggunaan
komponen-komponen elektronika seperti dioda,
transistor, thyristor, unijunction transistor, silicon
controlled rectifier (SCR), DIAC dan TRIAC.
Komponen elektronika yang digunakan mampu
menghasilkan daya yang besar atau menahan disipasi
daya yang besar.
