Abstract:
1. A power converter comprising: a power module including a semiconductor chip, a sheet conductor coupled to a main surface of the semiconductor chip, a coupling terminal electrically coupled to a direct current power source, and a resin material to seal the sheet conductor; a flow passage forming piece including a flow passage for flow of a cooling medium; and a cooler with a bottom, including an open section, a first cooling surface, and a second cooling surface opposite the first cooling surface, wherein the cooler stores the power module, wherein the flow passage forming piece includes an opening coupling with the flow passage, wherein the cooler is immersed into the flow passage from the open section, wherein the resin material includes a protruding section protruding from the open section of the cooler, wherein the coupling terminal is clamped to the protruding section, wherein a portion of the sheet conductor is coupled to the coupling terminal by way of a metal material that melts at a specified temperature, and wherein the metal material is mounted on the protruding section of the resin material.
