After start of an electric drive system, a controller reduces power output of an inverter responsive to sensed temperature of a power switch of the inverter, sensed current of a power electronics module, sensed DC-link voltage, and thermal impedance parameters of a DC-link capacitor being indicative of an estimated temperature of the DC-link capacitor that is greater than a threshold to maintain DC-link capacitor temperature lower than the threshold.
