Abstract
There are provided a smoothing capacitor () for storing an induced electromotive force generated by a three-phase induction motor (), a regenerative transistor (to) for switching a terminal voltage of the smoothing capacitor to carry out a power regenerating operation over a three-phase AC power supply (), a line voltage detecting portion () for detecting a line voltage of the three-phase AC power supply, a fundamental waveform generating portion () for generating, from a signal output from the line voltage detecting portion, a fundamental waveform defined to be a line voltage waveform of the three-phase AC power supply in which a source voltage distortion component is not mixed, a base driving signal creating portion () for creating a base driving signal to be used for an ON/OFF control of the regenerative transistor based on a signal output from the fundamental waveform generating portion, and a base driving signal output portion () for outputting the base driving signal.
