    摘要： A cooling structure of a power semiconductor device includes a cooling water passage and a plurality of fins. The cooling water for cooling the power semiconductor device flows through the cooling water passage. The plurality of fins are provided on a path of the cooling water passage and set up with a spacing therebetween in a direction orthogonal to a flow direction of the cooling water. The plurality of fins promote heat exchange between the power semiconductor device and the cooling water. The plurality of fins have ends facing the upstream side of a cooling water flow. The end of at least one fin among the plurality of fins is arranged so as to be displaced to a more upstream side of the cooling water flow than the ends of the fins adjacent to both sides of the at least one fin. By such a configuration, there is provided a cooling structure of a power semiconductor device and an inverter with excellent cooling efficiency.

    摘要： When an upper arm of U-phase has failed because of short-circuit, lower arms of V-phase and W-phase as the opposite arms are switching-operated. When only the lower arm of V-phase is turned on, a route of motor current passing through an IGBT element from a V-phase coil is formed, and therefore, the motor current returning to the short-circuited phase decreases. Further, by the switching operation of the arm opposite to the short-circuited arm, an AC current is induced in a motor generator. Therefore, it is possible to continuously drive the motor generator while preventing increase in the current passing through the short-circuited phase, without adding a new device structure. This ensures running of the vehicle in the limp mode.

    摘要翻译： 当U相的上臂由于短路而发生故障时，作为相对臂的V相和W相的下臂是开关操作的。 当V相的下臂仅导通时，形成从V相线圈通过IGBT元件的电动机电流的路径，因此返回到短路相的电动机电流减小。 此外，通过与短路臂相对的臂的开关动作，在电动发电机中产生交流电流。 因此，可以在不增加新的装置结构的同时，防止通过短路相的电流的增加而连续地驱动电动发电机。 这确保车辆在跛行模式下的行驶。
