A duty ratio V1/Vdc is multiplied with the correction coefficient, the corrected duty ratio is outputted, and an output of a current control amplifier 2 is superimposed on the corrected duty ratio so that a voltage command value V* is generated. PWM modulation is performed on the basis of the voltage command value V*.SELECTED DRAWING: Figure 2
