Abstract: A power supply system includes a main power storage device and a plurality of sub power storage devices. A converter is connected to selected one of the sub power storage devices to convert voltage between the selected sub power storage device and an electric power feeding line bidirectionally. When a request for switching the selected sub power storage device in use is generated, upper limits on electric power input/output to/from the selected sub power storage device are continuously varied. Thus, discontinuous variation of electric power input/output to/from the power supply system during the process for switching the selected sub power storage device can be avoided. Consequently, sudden change in a behavior of an electrically powered vehicle can be avoided.

Abstract: A vehicle includes a converter for stepping up power provided from a power storage device, and an inverter for converting the power output from converter and outputting it to an alternating-current motor for driving the vehicle. In the vehicle, a rectangular voltage control unit controls the inverter by means of rectangular wave voltage control that is based on a torque command value and the like, so as to control an output torque of the alternating-current motor. A system voltage control unit controls a system voltage, which is an output voltage of the converter. The system voltage control unit lifts a restriction on a system voltage command value based on an accelerator pedal position and the like, and then increases it. When increasing the system voltage command value during the rectangular wave voltage control for the inverter, a cooperative control unit increases the system voltage command value and the torque command value in a cooperative manner.

Abstract: When a DC/DC converter switches between a primary voltage control mode, a secondary voltage control mode, and a current limiting mode as operation modes, an I-term resetting processor outputs an I term depending on the duty ratio in the operation mode before being switched to a PID processor. The PID processor performs a PID control process based on the input I term. A drive duty ratio setter outputs a drive duty ratio immediately after the control mode switching, which is substantially equal to the duty ratio in the operation mode before being switched. As a result, the duty ratios in the operation mode before being switched and the operation mode after being switched are made continuous with respect to each other.

Abstract: A motor controller for an axial-gap motor permits a reduced size of the entire system of including a drive circuit and a power source of the motor, reduced cost, and higher reliability to be achieved by controlling the energization mode of the motor. The motor controller has a torque command determiner which inputs a first DC voltage to a first inverter at least either when a rotor is at a halt or when the number of revolutions of the rotor is a predetermined number of revolutions or less, supplies a field axis current for changing the magnetic flux of a field of the rotor to a first stator from the first inverter such that the amount of energization is temporally changed, converts an induced voltage developed in a second stator by the supplied field axis current into a second DC voltage by a second inverter, and outputs the second DC voltage, thereby charging a second battery.

Abstract: A three-phase regenerative drive (20) is operated based upon power from a single-phase AC source (12) and power from a DC source (14). The single-phase AC input power and the DC input power are converted to DC voltage on a DC bus (24) by a three-phase converter (22). DC power is provided from the DC bus (24) to a three-phase inverter having outputs connected to a motor (34). A controller (44) controls operation of the three-phase converter (22) based upon contribution factors of the AC and DC sources (12, 14) during motoring and regeneration. The controller (44) also controls an AC component of current from the DC source to reduce ripple current on the DC bus (24).
