    Abstract: An alternating current that is to be supplied to a motor generator is controlled by controlling an inverter using a target output of the motor generator and a result of detection of an angle-of-rotation sensor, and a voltage step-up is controlled in accordance with the target output of the motor generator. During operation of the motor generator, a stepped-up voltage obtained through the step-up converter is set to be higher (S13) when learning of the point of origin of the angle-of-rotation sensor has yet to be completed (S11), than when learning of the point of origin of the angle-of-rotation sensor has been completed. This eliminates malfunctions occurring in motor operation when learning of the point of origin of the angle-of-rotation sensor has yet to be completed.

    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.

    Abstract: A switching control device is applied to a motor generator drive system equipped with a boost converter and an inverter. In order to avoid generation of a superimposed surge voltage, the switching control device corrects a switching timing tsw of the booster converter so that a switching timing of the booster converter is not overlapped with a switching timing of the inverter. A booster converter switching correction means corrects the switching timing tsw of the correction target to bring forward and before a start timing tpa of the switching inhibition period Pp. This makes it possible to suppress fluctuation in output of a load due to deterioration in controllability of the electric power converter, for example, suppress fluctuation in output torque of a motor generator.

    Abstract: In some aspects, an actuation system includes an electrical positioning driver and an electrically-driven actuator. A voltage boost converter in the electrical positioning driver receives an input voltage. The voltage boost converter passes the input voltage to a voltage bus in the electrical positioning driver. The voltage on the voltage bus is converted to an actuator power signal that controls the electrically-driven actuator. The voltage boost converter boosts the voltage on the voltage bus to control a mechanical output performance of the electrically-driven actuator.
