Abstract

Disclosed is a downsized an integrated power-converter apparatus in which a plurality of power converter apparatuses is integrated, and to shorten a wiring connection distance in the power converter apparatus. The power-converter apparatus includes a power semiconductor module, a DC-to-DC converter, a capacitor module, a flow-path forming body for forming a flow path through which a refrigerant flows, a case, and a first DC connector for transmitting the DC current. The power semiconductor module is arranged in a position facing the DC-DC converter with the flow-path forming body interposed therebetween. The DC connector is arranged on one specified surface side of the case. The surface of the case is formed along an arrangement direction of the power semiconductor module, the flow-path forming body, and the DC-DC converter. The capacitor module is arranged between the surface of the case and the flow-path forming body, and is connected to the DC connector.
