Power conversion device

A power conversion device comprising:

• an inverter circuit in which arms are connected in parallel to each other between a DC positive terminal and a DC negative terminal in accordance with a number of phases of alternating currents of a plurality of phases, the arms for the respective phases each including two switch sections that are connected in series and to be brought into conduction in an on state and out of conduction in an off state, the power conversion device being configured to convert electric power between DC power and AC power of the plurality of phases while a connection point between the two switch sections of each of the arms is set as an AC input or output point of each phase, wherein
• each of the switch sections includes a switching element and a freewheeling diode connected in parallel to the switching element while a direction from the negative terminal to the positive terminal is set as a forward direction, the switching element is a first switching element or a second
• switching element that is higher in a switching response between the off state and the on state than the first switching element,
• the freewheeling diode is a first rectifying element or a second rectifying element that is shorter in a reverse recovery time than the first rectifying element, and
• in each of the arms, one of the switch sections including an upper-stage switch section connected to a positive terminal side and a lower-stage switch section connected to a negative terminal side is structured through parallel connection between the first switching element and the second rectifying element, and the other of the switch sections is structured through parallel connection between the second switching element and the first rectifying element.
