SEMICONDUCTOR MODULE AND POWER CONVERTER USING THE SAME

PROBLEM TO BE SOLVED: To provide a power converter having a cooling function in which downsizing and improvement of reliability and productivity required for productization can be achieved.SOLUTION: First power semiconductor elements 52 and 56 configuring an upper arm circuit, second power semiconductor elements 62 and 66 configuring a lower arm circuit, a first conductor plate 534 and a second conductor plate 584 disposed on one side and the other side of the first power semiconductor elements respectively, a third conductor plate 544 and a fourth conductor plate 574 disposed on one side and the other side of the second power semiconductor elements respectively are arranged so that a loop-shaped recovery current path is formed when recovery current flows in the order of the first conductor plate 534, the first power semiconductor elements 52 and 56, the second conductor plate 584, the third conductor plate 544, the second power semiconductor elements 62 and 66, and the fourth conductor plate 574. The loop-shaped recovery current induces eddy current 605 and 606 in a first radiator plate 522 and a second radiator plate 562, which reduces inductance in switching operation.
