摘要： PROBLEM TO BE SOLVED: To thinly form a heat receiving plate without lowering cooling efficiency by a method wherein the mounting part of an electric machine is provided between the heat receiving plate and a refrigerant flow path. SOLUTION: The heat generated on a self-extinguishing type element 12 and a snuffer resistor 13 during operation is transmitted to heat receiving plates 6A and 6B, the heat moves by transmitting to the refrigerant, e.g. water, which is forcedly circulated in the first refrigerant path and the second refrigerant flowing path. The water, which is heated up by absorbing heat, flows as shown by the arrows in the diagram, and it is cooled by radiation from a heat radiating part 11 where heat is exchanged by the outside air. The cooled water is sent out to the refrigerant flow path in the heat-receiving plates 6A and 6B by a circulation pump 10, and the self-extinguishing type element 12 and the snubber resistor 13 are continuously cooled. As the heat-receiving plates 6A and 6B are provided in such a manner that the mounting part of the first and the second refrigerant flow paths and the mounting part of the electric machine are provided separately, the heat-receiving plates 6A and 6B can be formed small in size.

Furthermore, the positive conductor 3 or negative conductor 4 on the semiconductor element side is bent so that it is parallel with either of the conductors 5, 6 on the capacitor side. The connection direction of a connecting bolt 5 for the positive conductor 3 and the positive conductor 5 is set different from the direction of connection of a connecting bolt for the negative conductor 4 and the negative conductor 6, and this structure enables connection of the semiconductor element-side conductors to the capacitor-side conductors so that the width of the conductors is large at the junctions.
