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: The present invention contemplates a hybrid vehicle capable of changing an amount to be charged to an electric power storage device in accordance with whether it is externally charged. The hybrid vehicle includes a control device inquiring of an occupant of the vehicle whether the occupant has an intention to go to a charging location for example at home. If so, the control device sets a target value for the electric power storage device's amount of a state (SOC) to have a value smaller than when the occupant does not have an intention to go to the charging location. This allows as much energy as possible to be received at the charging location and a vehicle can thus be obtained that less depends on an internal combustion engine and contributes to environmental protection.

Abstract: In a motor drive control system configured to include a converter capable of stepping up the voltage, when the locked state of MG2 operating as an electric motor does not occur (NO in S130), a voltage command value VHref for the converter output voltage is set according to respective required voltages of MG1 operating as an electric generator and MG2 (S140). In contrast, when the locked state of MG2 occurs (YES in S130), the voltage command value VHref is set to a limit voltage Vlmt or less for limiting the voltage step-up by the converter (S150, S180). When the locked state occurs, the converter output voltage is decreased and accordingly the DC voltage switched by the inverter is lowered, so that a switching loss at the switching device forming a part of the inverter is reduced and the temperature increase due to the heat generation can be suppressed.
