Abstract
This inverter, for electrical connection to a DC voltage source to supply an electric charge with three-phase current, includes a capacitive filter and a switching cell including, for each phase, a switching mode power supply circuit formed by two sets of controlled switches. Each set of controlled switches supplies a separate terminal of the switching cell, which also includes a sealed housing containing the switching mode power supply circuits. The housing is provided, on two opposite surfaces, with heat exchange means with a heat transfer fluid. A distributor is mounted, upstream from the housing, in a heat transfer fluid circulation circuit, to steer the heat transfer fluid toward the two opposite surfaces of the housing. The capacitive filter is cooled using at least one heat pipe. Part of this heat pipe, where the condensation of a fluid contained in the heat pipe occurs, is in thermal contact with the distributor.
