Abstract

PURPOSE: To increase the response speed through the synchronization effected by short-circuiting or releasing a short-circuit across the condenser for triggering the thyristor.
CONSTITUTION: Connected between an AC power supply 1 and a DC power supply A which are in common at one terminal are a comparison amplifier B, a trigger circuit C and a synchronous circuit D. The synchronous circuit D consists of a transistor 23, a Zener diode 26 and others. Through this circuit, the followed synchronization can be obtained: a triggering capacitor 18 is short-circuited across it and not charged when a thyristor 3 is in conduction, while at the time the thyristor 3 is cut off, the triggering capacitor 18 is released from its short-circuited state and starts to be charged when the potential at a terminal T2 of the thyristor 3 becomes higher more several volts than that at a terminal T1 thereof in any case the potential is positive or negative.
