Power module and power converter containing power module

摘要

A power module includes a semiconductor chip, a first coupling conductor with one main surface coupled to one main surface of the semiconductor chip, a second coupling conductor with one main surface coupled to the other main surface of the semiconductor chip, a coupling terminal supplied with electrical power from the direct current power source, and resin material to seal the semiconductor chip, and in which the resin member has a protruding section that protrudes from the space where the first and second coupling conductors are formed opposite each other, and the coupling terminal is clamped on the protruding section, and at least one of the first or second coupling conductors is coupled to a coupling terminal by way of a metallic material that melts at a specified temperature.
