Patent ID: 11750142

Abstract:
A system includes one or more electric motors, this system comprising a set of at least one load and an inverter comprising transistors, the inverter being intended to convert a DC voltage into an AC voltage that is intended to electrically power the set of at least one load, the inverter being able to be in a set of states comprising a nominal regime and a transitory regime wherein the set of at least one load draws, from the inverter, a power higher than a maximum power drawn from the inverter when the inverter is in nominal regime, the electrical-energy-converting system comprising means for cooling the transistors comprising a holder that is joined to at least one of the transistors of the inverter, the holder comprising a phase-change material that is able to melt, the system comprising one or more electric motors being configured so that, at a preset ambient temperature, the phase-change material melts when the inverter is in the transitory regime and so that, at this ambient temperature, the phase-change material does not melt when the inverter is in the nominal regime.
