<p>A vehicle electric power steering (EPS) control system includes a motor (48) operatively coupled to an EPS linkage arrangement (14), the motor comprising a first winding (72) and a second winding (84). Also included is a power source (68) for the motor. Further included is a controller (62) in operative communication with the motor and the power source. The controller includes a microprocessor (76) configured to receive input from a torque sensor (80) and a motor sensor (82). The EPS controller also includes a first field-effect transistor (FET) driver (74) in operative communication with the microprocessor and a first plurality of FETs (70) operatively connected to the first winding of the motor. The EPS controller further includes a second FET driver (88) in operative communication with the microprocessor and a second plurality of FETs (86) operatively connected to the second winding of the motor.</p>
