An electric vehicle propulsion system having a motor with first and second electrically isolated windings and a system control unit for controlling the motor, wherein the system control unit includes a first power bridge for driving the first windings and a second power bridge for driving the second windings.

Electric vehicle propulsion system employing AC induction motor control

A power bridge for an electric vehicle propulsion system, comprising a switching circuit including first and second switching elements operable between 'on' and 'off' states and a midpoint detector coupled to the switching circuit for detecting a failure of at least one of the first and second switching elements, where the midpoint detector is capable of detecting and isolating a failure when the switching elements are in the 'on' or the 'off' states.
