Abstract: A converter performs full-wave rectification on a single-phase voltage, thus outputting a rectified voltage across DC power supply lines. An inverter receives the rectified voltage and then supplies a three-phase AC current to an inductive load. Between the DC power supply lines is connected a charge and discharge circuit. The charge and discharge circuit includes a buffer circuit and a boost circuit. The buffer circuit includes a series connection between a capacitor and a switch. The boost circuit, which may be configured by a boost chopper, includes a switch, a reactor and a diode. The charge and discharge circuit provides and receives part of pulsations of the power input to the converter between the DC power supply lines.

Abstract: A driver circuit for driving an electrical motor coil is provided which comprises combined switched inductance boost voltage converter circuitry and switched inductance buck voltage converter circuitry. An input node of the driver circuit is provided to be coupled with the electrical motor coil, which provides the inductive element of both the boost and buck circuitry. Further the boost and buck circuitry share a storage capacitor, which provides the capacitive element of each circuitry, and a voltage developed across the storage capacitor by the boost circuitry forms an input of the switched inductance buck voltage converter circuitry. Bidirectional driving of the electrical motor coil is thus provided from a driver circuit which only need be supplied with a single unidirectional supply and the current drawn from that supply is significantly reduced because of the manner in which the boost and buck circuitry operate synergistically to recycle electrical power which is moved back and forth between the electrical motor coil and the storage capacitor. A corresponding driver board, electrical motor driver apparatus, method of operating a driver circuit and apparatus are also provided.
