POWER CONVERTER

摘要

The invention concerns a power converter powered by voltage successive feed (Ucat) consisting of insulated gate bipolar transistor (IGBT) static switches, in the form of at least an IGBT module (10) directly fixed on a cooling block (14) which is itself connected to fins (0) or the like. The invention is characterised in that an insulation (13) is provided between the cooling block (14) and the fins (0) and the cooling block (14) whereon the IGBT module(s) (10) is/are fixed is connected to a potential intermediate between the fins (0) potential and the peak of the power converter successive feed (+Ucat).
