IMPROVED RELIABILITY IN SEMICONDUCTOR DEVICE CONTROL

摘要

A gate control device (30) for a semiconductor device comprises at least one power supply module (42, 46), at least one optical communication interface (40, 44) for receiving optical signals (OS1, OS2) from two valve control units (36, 38) and converting them to electric signals for supply to a corresponding power supply module (42, 46), where in normal operations mode one valve control unit is an active valve control unit and the other is a standby valve control unit, where the optical signal of an active unit energizes the gate control device and provides semiconductor device controlling data, a semiconductor device control module (52) and a reliability control module (50) that performs selection of active valve control unit.
