Description

technical field [0001] The present invention relates to a power semiconductor module in which at least two or more power semiconductors mounted on a metal plate are functionally connected and accommodated in a single package, and an electric power steering device using the same. Background technique [0002] Conventionally, electronic circuits using power semiconductors that handle high power, such as inverter circuits and power supply circuits, have sometimes required further miniaturization in order to match the miniaturization of devices using such circuits. Furthermore, in order to further reduce the size of circuits using such power semiconductors, it is also necessary to efficiently dissipate heat from power semiconductors and the like mounted at a high density in order to achieve size reduction at low cost. [0003] For example, in a control device of a rotating electrical device such as a motor used in an electric power steering (EPS) of a vehicle such as an automobi...
