Fractional-Order Model Predictive Control of SiC PFC Converter

Due to the fractional-order characteristic of the PFC circuit, the traditional integer-order equation cannot describe the circuit model accurately. To increase the model description accuracy, the fractional-order theory is employed to describe the SiC PFC circuit model in this research, and then the model predictive control approach is applied to improve the PFC circuit's performance. The experimental results verify the feasibility of the proposed method.
