AN IMPROVEMENT IN OR RELATING TO THYRISTOR FIRED BY COLLAPSING VOLTAGE

摘要

46,093 THYRISTOR FIRED BY COLLAPSING VOLTAGE This invention is concerned with a thyristor device which can be fired by a collapsing voltage. The thyristor is switched from a forward blocking mode to a forward conducting mode when a displacement current produced by a collapsing voltage is concentrated under an auxiliary emitter, thereby causing sufficient carrier emission to fire the device.
