Abstract: PURPOSE:To amend waveform distortion, before the output voltage detecting signal of an inverter is introduced into a distortion correcting circuit, by avoiding fundamental wave component included in the signal by means of butting the component to the fundamental sine wave of a sine wave PWM inverter. CONSTITUTION:The waveform distortion correcting circuit of a sine wave PWM inverter 1 is composed of a voltage detecting section 2, an AC/DC converter 3, an oscillator 4, a reference sine wave generating circuit 5, a carrier wave generating circuit 6, a voltage setting section 7, a distortion correcting signal output section 10, a comparing section 12, and a gate circuit 13, and connects the waveform distortion of output voltage. The reference sine wave generating, circuit 5 is used as a fundamental wave output section, and to the section, a phase shifting section 14 and a subtracting section 15 are applied. Then, from voltage detecting signal, sine wave signal through the phase shifter 14 from said generating circuit 5 is deducted by the subtracting section 15, and the input of its deviation signal to the distortion correcting signal output section 10 is provided. Accordingly, even if fundamental component which is not cancelled by a band-pass filter is left, its value is made smaller.
