Abstract
A method and apparatus for controlling a change in a quadrant of operation of a brushless direct current motor. A quadrant change in an operation of a motor is identified. In response to identifying the quadrant change, selected ones of a plurality of switches in a switch bridge are selected to be controlled to couple a direct current power source to the windings of the motor to change a direction of an actual current in the windings.
