Power converter apparatus

Abstract

A power converter apparatus includes a substrateon which switching elements Q, Qto Qare mounted, positive and negative terminal interconnection membersmounted on the substrate, and a capacitorhaving a positive terminalconnected to the main body of the positive terminal interconnection memberand a negative terminalconnected to the main body of the negative terminal interconnection member. The interconnection members each have a plate-like main bodythat is located above and parallel to the substrate. The main bodies of the interconnection members are stacked to be close to each other while being electrically insulated from each other. Each of the positive terminal interconnection member and the negative terminal interconnection member further includes a plate-like extensionthat extends from the corresponding main body toward the substrate, and a terminal portionthat extends from the extension and is joined to the substrate. The extensions extend to positions closest to the substrate, while being parallel to and close to each other.
