Abstract

PURPOSE:To improve the following property for the variation in a power source voltage by giving a coefficient, which varies in inversely proportion to the value of a DC power source voltage, to a control signal, and offsetting a reactive power. CONSTITUTION:The control signal A which specifies the width, frequency, and phase of the fundamental wave of an output voltage of an inverter, and a triangular wave signal B which specified the modulating frequency from a triangular wave generator 15 are introduced into the voltage type pulse width modulation inverter 2 via pulse width modulator 16. At this time the signal, which is obtained by vectorially combining an AC signal directly corresponding to the voltage of a system 4 and an AC signal corresponding to the voltage whose phase of the system voltage is shifted by 90 deg. in a phase shifter 12 at a variable rate, is used as the contol signal A. To the directly corresponding AC signal, the coefficient which varies in inversely proportion to the voltage value of the DC power source 1 is given.
