CONMUTADOR DE CARGA DE SEMICONDUCTORES CON TIRISTOR

摘要

A power switch device comprises an asymmetrically blocking thyristor (ASCR), with which a diode is connected in series. The ASCR as well as the diode require only about one half the central zone thickness as compared with a symmetrically blocking thyristor laid out for the same blocking voltage in reverse direction (URRM). For the series connection of the ASCR and diode, this results in a much lower blocking delay charge (Qrr).
