<P>PROBLEM TO BE SOLVED: To provide an electric power conversion system which protects a semiconductor module from excess current and shortens a power terminal. <P>SOLUTION: An electric power conversion system 1 includes a laminate 11 formed by laminating multiple semiconductor modules 2 and multiple cooling tubes 10. Each semiconductor module 2 has a body part 20 incorporating a semiconductor element forming an electric power conversion circuit. A power terminal 21, establishing electrical continuity with the semiconductor element, protrudes from an end surface of the body part 20. Each cooling tube 10 cools the semiconductor module 2 from both main surfaces of the body part 20. A bus bar 3 connects with the power terminal 21, and a fuse part 4, which fuses when a current equal to or larger than a predetermined value flows, is formed at the bus bar 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
