Abstract
An inverter comprises output switches for generating motor phase currents for application to an electrical motor based on a commanded torque. A current sensor is arranged for detecting motor phase currents applied to the electrical motor by an inverter. A voltage sensor is configured for measuring voltages applied to the electrical motor by the inverter. An output port is capable of outputting output signals of the detected motor phase currents and measured voltages for processing by a vehicle controller. The output signals are suitable for input to a vehicle controller for determining whether or not to generate an override control signal. An input port is configured for receiving the override control signal from the vehicle controller. The input port is coupled to an override input module for switching off a supply of electrical energy to the electric motor.
