Abstract

PURPOSE:To control a DC bus voltage to an always stable given value, even if a load undergoes a sudden change, by detecting the DC side current of an inverter and by inputting said current to a voltage control circuit. CONSTITUTION:A voltage control amplifier 9 performs a voltage feed-back control by using the output signal of a reference voltage setter 7 as a reference value and the output from a voltage detector 8 as a negative feedback quantity. Also, after the output from a current detector 18 has been made to pass through a filter circuit 19, the output signal therefrom is synthesized with the output signal of said voltage control amplifier 9 by a synthesizer 20. The output signal of said synthesizer 20 shows a value determining the amplitude of a three-phase sinusoidal reference signal and that of computing elements 11-A, 11-B, 11-C becomes a three-phase sinusoidal current reference. In this manner, the DC side current of an inverter 4 is taken in as the control input of a voltage feedback control loop to compensate a disturbance.
