Abstract
A power conversion device comprises an inner coil which can transmit power between an external coil by coupling magnetically with the external coil, an inverter whose AC side is connected to the inner coil and power conversion can be performed between the AC side and a DC side and a bidirectional DC/DC converter which comprises an intermediate capacitor, is connected to the DC side of the inverter and can perform power conversion bidirectionally between a DC power source, which is connected to a side which is opposite to the side of the inverter, and the inverter, wherein in switching operation from power reception to power transmission where power reception operation is switched to power transmission operation, after control of discharging charges which are accumulated in the intermediate capacitor is performed, the power transmission operation is started.
