The power conversion module is supplied from a DC source and has static semiconductor Insulated Gate Bipolar Transistor (IGBF) switches to convert to alternating current. The static devices (10) are attached directly to a cooling block (14) and the insulation (13) between the cooling block and the cooling fins (0) is configured so that the cooling block is connected to an intermediate potential between the potential of the fins and the supply potential. |
