A power conversion control device includes a modulation-wave generating unit generating a modulation wave based on output voltage phase angle command and modulation factor, a carrier-wave generating unit that, in a case of non-overmodulation state, generates a triangular wave or saw-tooth wave as the carrier wave, and, in a case of overmodulation state, generates, as the carrier wave, a signal fixed to −1 in a first section that is a predetermined range centering on timing corresponding to a peak position of the modulation wave, generates, as the carrier wave, a signal fixed to +1 in a second section obtained by shifting the first section by a half cycle of the modulation wave, and generates, as the carrier wave, a triangular wave or saw-tooth wave in remaining third section, and a comparing unit that compares the carrier wave and the modulation wave and generates a switching signal.
A power conversion control device that controls, based on a modulation wave and a carrier wave, a power conversion device that converts direct-current power into alternating-current power, the device comprising:
