Document Type and Number:
Japanese Patent JP4424421
Kind Code:
B2
Abstract:
A carrier frequency setting unit (64) sets a carrier frequency (FC) based on a torque command (TR) and a motor rotation number (MRN) of a motor generator. A PWM signal producing unit (68) produces phase modulated waves corresponding to respective phase voltage commands (Vu, Vv and Vw), and produces respective phase PWM signals (Pu, Pv and Pw) corresponding to a relationship in magnitude between the respective phase modulated waves and a carrier having the carrier frequency (FC). A PWM center control unit (66) produces a PWM center correction value (CE) for variably controlling the PWM center when the carrier frequency (FC) is lower than a predetermined frequency, and provides the same to the PWM signal producing unit (68).
