| Abstract: | Based on the mathematic model of a three-phase PWM rectifier,the paper studies the control strategy of rectifier.A double closed-loop control system based on current and voltage closed-loop of PI regulator is designed.A digital controll system based on DSP and CPLD is constructed and the design methods of hardware and software are pre-sented.The experimental results show that the rectifier could effectively restrain the harmonic pollution and the system presents better dynamic and static performances. |
