| Abstract: | In this paper, Simple introduction to the principle and control strategy of the traditional Boost-PFC system is given, and based on the old algorithm, an advanced dual-loop controlled PFC algorithm is proposed. The algorithm can improve system stability, suppress the interference caused by the input voltage ripple. The detailed parameters design and the software design flow using TMS320F2812 digital signal processor are provided. A MATLAB-based simulation model is established and the simulation and experiment results verify the correctness and feasibility of the algorithm. |
