<p>A power converter (500) for a switched reluctance motor or a permanent magnet brushless direct current (dc) motor including first and second partial circuits (553, 554) for forming multiple conduction circuits in cooperation with first and second phase windings (505, 508) of the motor. The contoller (704) also includes a switch (555) operable to open and close a first conduction circuit, which includes the first phase winding (551), and to regulate energization of the first and second phase windings of the motor through opening and closing the first conduction circuit. Control of the switch (555) provides four-quadrant operation of the motor through regulated energization of the first and second phase windings (551, 552).</p> |
