    摘要： Fluctuations in output of an AC electric motor are restrained without increasing electromagnetic noise of a boost converter. When subjecting the AC electric motor to rectangular wave voltage control, output torque T is controlled by varying a voltage phase φv. In a region where a voltage phase is large (φv=θ2), fluctuations in torque T relative to changes in a DC voltage VH corresponding to the amplitude of a rectangular wave voltage are larger than in a region where the voltage phase is small (φv=θ1). The AC electric motor is controlled such that the rectangular wave voltage control in a region where voltage phase φv is larger than a limit-phase line PLN indicated by a set of limit phases set for each DC voltage VH is avoided.

    摘要： An electrically powered vehicle includes a motor generator configured to be capable of transmitting and receiving torque to and from a driving shaft coupled to a driving wheel; a DC power supply including a power storage device; and an inverter for performing bidirectional DC/AC power conversion between the DC power supply and the motor generator. The MG-ECU controls a plurality of power semiconductor switching elements to be turned on/off in accordance with a torque command value and a state value of the motor generator. When an accelerator pedal is released, the MG-ECU controls the inverter to superimpose a DC current component on an AC current of each phase in the motor generator in accordance with the state of charge of the power storage device.
