Description

technical field [0001] The present invention relates to a semiconductor device, and more particularly to a semiconductor device for electric power including an IGBT module used in a drive circuit for driving a drive motor of an electric vehicle. Background technique [0002] In an electric vehicle such as an electric automobile, a converter device for driving a driving motor thereof is used. The converter device includes a circuit connecting the conversion elements through a bridge circuit structure. The converter device switches the current flowing in the drive motor by appropriately turning on / off the switching elements of the bridge circuit. As conversion elements (power semiconductor elements) constituting the bridge circuit, power transistors, IGBTs, FETs, IEGTs, and the like are widely used. The converter device generally has a module structure in which a plurality of conversion elements are housed in one package. [0003] When the driving motor of an electric vehic...
