Abstract
PURPOSE:To avoid DC magnetic-deflection, by a method wherein DC component is detected, and wherein the component is converted to a continuous error command value with an error amplifier provided with a proportional element and an integral element, and wherein the command value and the output value of a multiplier are combined with each other. CONSTITUTION:The controlling system of a DC-AC power converter is provided with a multiplier 9, a PWM generator 10, a waveform detector 12, a DC component detecting section 13, an error amplifier 14, and a combining unit 15. Then, one waveform among the input current waveform or output current waveform of an inverter unit 1, the terminal voltage waveform of a smoothing reactor 2, or the primary input terminal voltage waveform of an inverter transformer 3 is detected, and said system consists of a DC component detecting block 101 consisting of the DC component detecting section 13 for detecting DC component and the error amplifier 14 provided with a proportional element and an integral element, and a constant-voltage controlling block 102 consisting of the PWM generator 10 and the like, and the output of the DC component detecting block 101 is fed back to the output of the multiplier 9 of the constant- voltage controlling block 102 by the combining unit 15.
