Document Type and Number:
WIPO Patent Application WO/2014/034331
Kind Code:
A1
Abstract:
A power conversion apparatus relating to the present invention is provided with: power semiconductor modules (300W-1, 300U-2), each of which has a power semiconductor element that converts a direct current into an alternating current; a flow channel forming body (12) that forms a flow channel having a cooling medium flowing therein; and a bus bar module having an alternating current bus bar (802A) sealed by means of an insulating resin material (92), said alternating current bus bar transmitting the alternating current. The flow channel forming body forms first and second openings connected to the flow channel, the power semiconductor module is disposed to the flow channel forming body such that the first opening is covered with the power semiconductor module, and the bus bar module is disposed to the flow channel forming body such that the second opening (124) is covered with the bus bar module.
