1. A system comprising:
an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes:
one or more controllers configured to provide a test signal to control a gate leakage detection operation; and
a power module including:
a phase switch including one or more phase power switches; and
a point-of-use controller configured to detect a gate leakage of the phase switch based on the test signal, wherein the point-of-use controller includes a current to voltage converter and a resistor divider.
