Abstract

PURPOSE:To decrease an AC component flowing through load by controlling a switching element so that all time integral value of DC output voltage is equalized at each period divided in plural number of each half cycle of an AC power supply. CONSTITUTION:The output of an auxiliary transformer T1 connected to the AC power supply V is applied to an integrator I while difference P-Id between current command value P and motor currents Id and the output of said integrator I are compared by means of a comparator C, a thyristor Th1 or Th2 is supplied with ignition pulses from a gate amplifier GA1, and conducted and DC voltage E0 is generated. On the other hand, arc extinguishing pulses are supplied from a gate amplifier GA2 by the output of a synchronous signal generating circut SG. Accordingly, the AC component of the motor currents Id can be decreased.
