Abstract :
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.
