Abstract: According to pulse-width modulation(PWM)characteristics of brushless DC motor(BLDCM)and principle of the resonant DC link inverter(RDCLI),a controller was designed for BLDCM driven by parallel resonant DC link inverter,using of PWM specific integrated chip and complex programmable logic device(CPLD).Digital simulation and experimental results show that the controller designed realizes function of RDCLI and PWM operation of BLDCM.
