摘　　要：针对三相PWMAC/DC变换器的输入电流调节,提出了一种滑模电流控制策略,其直流侧输出电压通过PI控制器调节。在该控制策略下,PWMAC/DC变换器具有功率因数为1的高输入电能质量和极佳的输出电压特性。实验结果证明了该方案的有效性。This paper presents a sliding-mode current control scheme for input currents regulation of three-phase PWM AC/DC converter.In the mentioned scheme the DC side is regulated based on a PI controller.Under the proposed control method,the PWM AC/DC converter is of high input quality of unity power factor and high performance of output voltage. Experimental results validate the effectiveness of proposed control method.
