ABSTRACT:
A PWM operation unit includes a modulation-mode selecting unit selecting a two-phase modulation mode signal and a carrier-wave-synchronous-mode select command, a modulation-wave generating unit generating a modulation wave in response to the two-phase modulation mode signal, a carrier-wave generating unit generating a carrier wave in response to the carrier-wave-synchronous-mode select command, and a comparing unit comparing the modulation wave with the carrier wave. In a two-phase modulation mode, the PWM operation unit controls the carrier-wave generating unit such that a carrier wave frequency is set to an integral multiple of a modulation wave frequency.
