Abstract

PURPOSE: To eliminate the damage of a thyristor by a device for protecting a thyristor converter by temporarily interrupting the stop of a gate pulse signal by a switching element when a damage occurs during a gate pulse.
CONSTITUTION: When a power supply malfunction occurs during the period while a gate control signal is generating to thus generate a power supply malfunction signal, a power supply malfunction signal to an OR gate 13 is generated after the period while the gate control signal is generating is ended. After a gate current incorporates a sufficient pulse duration, a current will therefore flow through the switching element 14 by a switching signal. Accordingly, the damage of a thyristor due to insufficient pulse duration of the gate is prevented.
