Title: Trigger signal generator circuit for optical thyristor converter
Inventor: ITO TAKASHI
IPC: H02M1/092
Filed: 1985-12-12
Abstract: PURPOSE:To effectively protect alight emitting element by firing a bypass switch by a malfunction detection signal generated when a continuous energization time to the element is a predetermined time or longer. CONSTITUTION:A switching element 5 is conducted only for a short time controlled by a control circuit 4 at a normal time, and the power of a power source 1 is supplied through a limiting resistor 2 to a light emitting element 6. Since a continuous current flows when a shortcircuit defect occurs due to a breakdown of the element 5, a current flowing time malfunction detector 9 detects a malfunction, a firing circuit 1 operates to fire a bypass thyristor 11. Thus, a current from the power source 1 is bypassed to set a current to the element 6 to zero.
