摘要： A control device determines whether a motor generator is controlled in a PWM control mode, an overmodulation control mode or a rectangular-wave control mode. If a command to perform a boosting operation by a voltage step-up converter is issued while the motor generator is controlled in the rectangular-wave control mode, the control device controls an inverter to drive the motor generator by switching the control mode to the overmodulation or PWM control mode. Further, the control device controls the inverter to drive the motor generator by suppressing increase of a torque command value.

摘要： A map holding unit holds, in the form of a map, a voltage control amount (Vq_map) of the q axis in a case where no demagnetization of a permanent magnet motor occurs. Based on a motor revolution number, namely the number of revolutions of the motor (MRN) provided from a revolution number detection unit, a demagnetized state calculation unit calculates a rotational angular velocity (ω). Then, based on the voltage control amount (Vq_map) from the map holding unit, a voltage control amount (Vq) to be controlled that is provided from a PI control unit and the rotational angular velocity (ω), the demagnetized state calculation unit calculates an amount of demagnetization (P(Vq_map−Vq/ω) and outputs, if the amount of demagnetization is greater than a predetermined value, an operation signal (OPE) for controlling the operation of the permanent magnet motor.

The power converter is configured to be switchable, by the control of the plurality of switching elements, between a parallel connection mode in which DC voltage conversion is executed with the DC power sources connected in parallel with a power line and a series connection mode in which DC voltage conversion is executed with the DC power sources connected in series with the power line. Each of the switching elements is arranged to be included both in a power conversion path between the first DC power source and the power line PL and a power conversion path between the second DC power source and the power line.
