Abstract
A vehicle includes an inverter having a supply bus including a contactor operable to conduct current through a resistive element connected to a capacitive element having a voltage supplied by a battery. The vehicle includes a controller configured to energize a first gate of the inverter. The energization is responsive to the voltage exceeding a threshold. The controller is configured to detect current flow between a first phase associated with the gate and the bus based on a voltage drop associated with the voltage.
