Title: Gate circuit for gate turn-off thyristor
Inventor: MIZOHATA FUMIO
IPC: H03K17/732
Filed: 1992-07-22
Abstract: PURPOSE:To prevent a gate-turn-off thyristor from being broken by impressing a turn-off pulse current again at the time of detecting the negative state of gate potential due to an external factor when the thyristor is in ON operation. CONSTITUTION:When an ON gate switch 12 and a turn-on pulse generating switch 17 are turned on, a gate current Ig is made a constant current by the constant current control of a chopper circuit 2. In this status, an oscillation current is allowed to flow between the gate and cathode of the gate turn-off thyristor(GTO) 1 due to an external factor, and when reverse bias is set up between a gate and a cathod, a comparator 35 detects the state, drives an one-shot multivibrator 32 and turns on a turn-on pulse generating switch 33 for a fixed period. Thereby the current Ig is allowed to flow into the GTO1 again as the sum of an oscillation waveform between a capacitor 25 and a reactor 21 and a discharge current between a capacitor 26 and a resistor 23 and the GTO1 is prevented from being broken.
