Characteristics of the high speed SI thyristor and its application as the 60kHz, 100kW and the efficiency of more than 90% inverter

Abstract

Very low-loss, very high speed and snubber-circuitless performance of the newly fabricated high power 1200V–300A class of the static induction (SI) thyristor is introduced and it is applied to the 60kHz–100kW high efficiency (90%) inverter for induction heating.
