A power converter capable of enhancing electric current detection accuracy by minimizing inductance of gate wiring. A power converter, particularly suitable for railway vehicles, includes a power semiconductor module 1, 2 equipped with a main emitter terminal 12, 22, a gate terminal 13, 23 and an auxiliary emitter terminal, 14, 24, and a gate drive substrate 15, 25 connected to the power semiconductor module, wherein the power semiconductor module and the gate drive substrate are connected by a metal conductor plate 16, 26. The metal conductor plate may connect the main emitter terminal and the gate drive substrate. The metal conductor plate may be installed between the main emitter terminal and another conductor plate installed above the main emitter terminal. The power semiconductor module may be an IGBT (Insulated Gate Bipolar Transistor). |
