Abstract

PURPOSE:To control a fluctuation in output voltage by catching a change in output current which causes a fluctuation in the output voltage in an inverter wherein the fluctuation is supplied to a voltage control system and the voltage control signal in the inverter is predictively varied by only the amount which almost corresponds to an expected fluctuation in voltage. CONSTITUTION:In addition to constant-voltage control for an amplifier 10 in a multiplex pulse-width modulation inverter, a forecasting control signal is added to an adder 9. In this way, if the amount of a change in signal Es is bigger than a fixed value I1 in a decision circuit 11 when a sudden change in IL occurs, an analog gate 8 is opened for a fixed time TA by operating a timing element MS1 in the circuit 11 to pass the signal Es for a period of t0 through t1 only and a phase control circuit 6 is predictively controlled by only the amount corresponding to the amount of a change in IL.
