Abstract

A power electronics unit 100 for an aircraft and a method of determining the integrity of a power electronics unit 100 are provided. The power electronics unit 100 comprises an electric machine controller 120; a heatsink 105 arranged to conduct heat from the electric machine controller 120; a housing 106 comprising a sealed internal volume enclosing the electric machine controller 120 and heatsink 105; a dielectric liquid 107 partially filling the internal volume to cover the electric machine controller 120; a gas pocket 108 within the internal volume; a pressure sensor 110 arranged to measure a pressure of gas within the gas pocket 108; a temperature sensor 117 arranged to measure a temperature within the internal volume; and a controller 118. The controller 118 is configured to receive signals from the pressure sensor 110 and temperature sensor 117, determine a pressure and temperature from the received signals and provide an output signal dependent on the determined temperature and pressure.
