Abstract: A power converter for a switched reluctance motor or a permanent magnet brushless direct current (dc) motor may include first and second partial circuits for forming multiple conduction circuits in cooperation with first and second phase windings of the motor. The controller also includes a switch operable to open and close a first conduction circuit, which includes the first phase winding, 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 provides four-quadrant operation of the motor through regulated energization of the first and second phase windings.

Abstract: A voltage regulation system maintains the output voltage of a permanent magnet generator at an essentially constant level. The stator coils located within the permanent magnet generator are divided into a number of sub-coils. A buck/boost voltage can be applied to selected sub-coils such that the output voltage generated by the permanent magnet generator is increased or decreased. A number of switches are connected to the sub-coils to allow the sub-coils to be connected in a number of different configurations. Connecting the sub-coils in a particular configuration and applying a buck/boost voltage to selected sub-coils based on the monitored output voltage allows the voltage regulation system to maintain an essentially constant output voltage.

Abstract: A control device determines whether a motor generator is controlled in a PWM control mode, an overmodulation control mode or a rectangular-wave control mode. If a command to perform a boosting operation by a voltage step-up converter is issued while the motor generator is controlled in the rectangular-wave control mode, the control device controls an inverter to drive the motor generator by switching the control mode to the overmodulation or PWM control mode. Further, the control device controls the inverter to drive the motor generator by suppressing increase of a torque command value.
