在单相交流斩波电路的基础上，提出了一种新型的交流斩波电路拓扑及相应的PWM方法。为了提高高压性能，本文采用了平均电压和瞬时电压双闭环控制，并带有占空比前馈。最后采用并联运行控制方法实现均流。实验结果验证了所提出的拓扑结构和控制方案的正确性和可行性。
Based on the single-phase AC chopper circuit, a novel AC chopper topology with the corresponding PWM method is proposed. To improve high voltage performance, dual- loop control including both mean voltage and instantaneous voltage is used in this paper, with duty-cycle feed-forward. At last, parallel operation control method is used to realize the current sharing. The experimental results verify the correctness and feasibility of the proposed topology and control scheme.
