Abstract
PURPOSE: To stabilize the gate trigger circuit of a frequency converter against the load variations by applying gate reverse bias voltage in response to the thyristor anode current zero crossing time.
CONSTITUTION: When the anode current of a thyristor 33 becomes zero, it is detected by a zero cross detector circuit 47 to thereby reset a pulse duration setting circuit 45 with the output signal Zc from the circuit 47. Then, a gate drive circuit 46 is operated by the output of the circuit 45 to thus apply the gate reverse bias voltage to the thyristor 33. Thus, it can provide a gate trigger circuit stable against the load variations.
