摘要： A carrier frequency setting unit (64) sets a carrier frequency (FC) according to the torque command (TR) of a motor generator and the number of motor rotations (MRN). A PWM signal generation unit (68) generates phase modulation waves corresponding to respective phase voltage commands (Vu, Vv, Vw) and generates phase PWM signals (Pu, Pv, Pw) according to the magnitude relationship between each of the phase modulation waves and a carrier wave having the carrier frequency (FC). A PWM center control unit (66), when the carrier frequency (FC) is lower than a predetermined frequency, generates a PWM center correction value (ΔCE) for variably controlling a PWM center and outputs to the PWM signal generation unit (68).

摘要： A carrier frequency setting unit sets a carrier frequency based on a torque command and a motor rotation number of a motor generator. A PWM signal producing unit produces phase modulated waves corresponding to respective phase voltage commands, and produces respective phase PWM signals corresponding to a relationship in magnitude between the respective phase modulated waves and a carrier having the carrier frequency. A PWM center control unit produces a PWM center correction value for variably controlling the PWM center when the carrier frequency is lower than a predetermined frequency, and provides the same to the PWM signal producing unit.

摘要： In one coordinate system of arbitrary rectangular coordinate systems including a coordinate system in which the position of a stator is fixed, a coordinate system in which the position of a rotor is fixed, and a coordinate system which rotates at a rotational frequency which is n times (n is an integer which is not 0 or 1) that of the rotor, a filter on any other coordinate system is defined. Further, driving of a motor is controlled by utilizing this filter. As a result, a coordinate transformation operation need not be individually performed with respect to control variables.

摘要： In the hybrid vehicle, a boost converter is controlled to make a post-boost voltage or a voltage on the side of an inverter become a target post-boost voltage corresponding to a target operation point of a motor in accordance with a target post-boost voltage setting map that divides an operation region of the motor into a non-boost region and a boost region when a operation point of the motor is included in the boost region. The target post-boost voltage setting map is prepared so that the non-boost region includes a region in which a loss produced by driving the motor when not boosting the post-boost voltages becomes smaller than the loss produced when boosting the post-boost voltage and the boost region includes a region in which the loss produced when boosting the post-boost voltage becomes smaller than the loss produced when not boosting the post-boost voltage.
