Abstract
PURPOSE: To perform stable starting without causing a commutation fault, despite the change in resonance frequency due to the fluctuation in a load circuit, by supplying an inverter with a gate pulse surely after the peak value of an AC voltage.
CONSTITUTION: The peak value of the output of a full wave rectifier 10 is detected and retained by a peak value detector 11. The peak value is divided by a voltage divider 12 and then applied to a comparator 13. When the full wave rectified output decreases below a value held by the voltage divider 12, the comparator 13 produces a pulse in each half period. The pulses are distributed to the thyristors of an inverter 4 by a distributor 14. The inverter is thus supplied with the gate pulses surely after the peak value of the AC voltage. This results in assuring a commutation margin time.
