摘要
针对单位功率因数整流器的控制要求,提出了一种利用锁相环(PLL)来检测基波电压相位,控制整流器交流侧电流与交流侧基波电压同相位的控制策略。通过仿真试验证明了这种控制策略有很好的动静态性能。
According to the requirement of controlling the unity power factor rectifier, a novel method , a phase locked loop (PLL), is used to track the phase of fundamental voltage. By using this method, the desirable phase of the rectifier's current can be equal to that of fundamental voltage . Simulation test demonstrates that PLL has good dynamic characteristic and static characteristic.
