A controller (500) in an electric drive system is used to determine whether a phase current imbalance in the output winding of a power generator (204) exists. During operation, the controller (500) receives a set of power generator diagnostic values corresponding to the phase currents output by the power generator (204). Next, the controller (500) determines a set of expected operating phase current values. The controller (500) then compares the obtained diagnostic values to one or more corresponding expected operating values. If the difference is greater than a threshold, the controller (500) provides an appropriate fault indication indicative of a phase current imbalance.
