摘要
This power conversion device performs DC/AC power conversion via an intermediate bus, and includes: a first DC/DC converter provided between a DC power supply and the intermediate bus; a second DC/DC converter provided between a DC-side capacitor and the intermediate bus; an intermediate capacitor connected to the intermediate bus; a DC/AC converter provided between the intermediate bus and an AC grid; and a control unit configured to control the first DC/DC converter, the second DC/DC converter, and the DC/AC converter, the control unit making such current command value setting that mainly the second DC/DC converter supplies a reactive current flowing through the intermediate bus.
