| Abstract: | In this paper, the mathematical model of three-level rectifier is constructed, and the sliding-mode control strategy is studied. A double closed-loop control system based on current closed-loop of PI regulator and voltage closed-loop of the sliding-mode control regulator had been designed. The results of the emulation and the experiment were present. The experiment showed that the rectifier could effectively restrain the harmonic pollution and the system presents better dynamic and static characters. |
