The invention includes a three-phase full-bridge power converter, a motor generator driven by the power converter, a pulse number generator which determines the number of pulses included in the driving signal for one electrical cycle, a voltage command generator which determines a modulation factor and a phase angle of driving voltage, and a pulse generator which generates the driving signal, and, in this invention, the pulse generator generates the driving signal having a pulse waveform which minimizes power loss in the power generator and the motor generator according to the number of pulses, the modulation factor, and the phase angle.
