A method of monitoring aging for an electric drive system having a power semiconductor device, comprising: providing said power semiconductor device coupling in parallel a transistor and a freewheeling diode having opposite polarities, energizing the electric drive system such that electrical current flows alternatively through said transistor and said freewheeling diode of said power semiconductor device; determining using a voltage sensing mechanism a determined value indicative of a voltage across one of the transistor and the freewheeling diode, at a level of the electrical current where the voltage is substantially independent of a temperature of the one of the transistor and the freewheeling diode; comparing the determined value with a reference value; and outputting a signal indicative of an aging state of the power semiconductor device responsive to a difference between the determined value and the reference value;
