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