Abstract

PURPOSE:To turn the output current waveform of an inverter into a sine wave, by compensating for the fundamental wave component and harmonic component of output voltage due to on-delay. CONSTITUTION:So far as a coordinate transformer 6 is concerned, the phase angle thetak of voltage compensating for output voltage drop due to on-delay from a compensation voltage arithmetic circuit 11 is applied to cosine function generators 16, 17, 18. The input of the scale y of voltage and the output signal of the cosine function generators 16, 17, 18, to multipliers 19-21 is provided, and the three-phase compensation voltage command signal of a stator coordinate system is found, and the output is directed to adders 7-9. By the adders 7-9, the three-phase AC voltage command signal of the stator coordinate system from a coordinate transformer 5 and said compensation voltage command signal are added to each other, and the output of the output voltage command signal of a PWM inverter 1 is directed to a PWM pulse generating circuit 10.
