AC VOLTAGE OUTPUT APPARATUS AND HYBRID VEHICLE INCLUDING THE SAME

摘要

A first inverter control unit (62) includes a harmonic generation unit (112). The harmonic generation unit (112) generates a harmonic voltage instruction having a phase opposite to a harmonic generated at a neutral point of a motor-generator (MG1) when the motor-generator (MG1) revolves, based on motor revolution number (w1) of the motor-generator (MG1). A PWM signal generation unit (114) generates a signal (PWM1) based on a voltage instruction obtained by superimposing an AC voltage instruction from an AC output control unit (64) and the harmonic voltage instruction from the harmonic generation unit (112) onto each voltage instruction of U-phase, V-phase and W-phase from a conversion unit (110).
