Abstract
The power converter Aincludes a semiconductor device B, and a substrate H on which the semiconductor device Bis mounted, where the semiconductor device Bincludes a control chip constituting a primary control circuit, a semiconductor chip constituting a secondary power circuit, and a transmission circuit for electrically insulating the primary control circuit and the secondary power circuit and for signal transmission between the primary control circuit and the secondary power circuit. The substrate H has a conductive portion K. The power converter Aincludes a connecting terminal Tdisposed on the substrate H and electrically connected to the conductive portion K. The power converter Aincludes a conductive path Dthat is at least partially formed by the conductive portion K of the substrate H, and that electrically connects the primary control circuit and the connecting terminal T. Such a configuration contributes to downsizing the power converter A
