Due to the fractional-order characteristic of the PFC circuit, the traditional integer-order equation cannot describe the circuit model accurately. In this paper, the fractional-order theory is used to describe the PFC circuit model to improve the model description accuracy, and then the model predictive control strategy is used to improve the performance of the PFC circuit. The experimental results verify the feasibility of the proposed method.
