Abstract:
A method for monitoring an inverter module for a multi-phase electric motor/generator includes deactivating operation of the inverter module, monitoring voltage on a high-voltage bus configured to supply electric power to the inverter module, detecting occurrence of a true fault when a change in the voltage on the high-voltage bus is greater than a predetermined threshold, and detecting occurrence of a false fault when the change in the voltage on the high-voltage bus is less than the predetermined threshold.
