Zusammenfassung:	A power conversion device 200 comprises a power conversion unit of a three phase full bridge type including upper arm switching devices 328 and lower arm switching devices 330, and a controller 170 that outputs drive signals to these switching devices 328, 330. This power conversion device 200 forms alternately a first interval in which the upper arm switching devices 328 and the lower arm switching devices 330 are switched to ON for different phases, and a second interval in which, for all phases, either the upper arm switching devices 328 or the lower arm switching devices 330 are switched to ON, according to electrical angle.
