Abstract

The power conversion control device according to the present invention controls a power conversion unit (2) for converting DC power to AC power on the basis of modulated waves and carrier waves and is provided with: a modulated wave generation unit (6) which generates modulated waves on the basis of an output voltage phase angle command and a percentage of modulation; a carrier wave generation unit (5) which if there is not an over modulated state generates as carrier waves triangular waves or sawtooth waves and if there is an over modulated state generates as carrier waves a signal fixed to 1 in a first section which is a specific region centered on a timing corresponding to the peak position of a modulated wave a signal fixed to +1 in a second section which is the first section having been shifted by half a cycle of the modulated wave and triangular waves or sawtooth waves in the remaining third section; and a comparison unit (7) which compares the carrier waves and the modulated waves and generates a switching signal.
