A pulse width modulation control according to the present invention is performed such that, when changing a modulation rate when a sinusoidal wave is used as a waveform of a modulation wave, the modulation rate is continuously changed from a normal modulation region to an overmodulation region, and, in switching between the normal modulation region and the overmodulation region, the modulation rate in the normal modulation region is not discontinuous with the modulation rate in the overmodulation region. In the overmodulation region, limiting the modulation rate α prevents a jump phenomenon in pulse width from occurring and the continuity of the pulse width from disappearing due to the jump phenomenon. The upper limit αupper of the modulation rate α is a threshold at which the pulse width of a PWM pulse signal jumps to a duty ratio of 50 %, and limits the modulation rate α to less than the threshold.
