A Mutually Balanced Two-Phase Interleaving Parallel Control Method of CRM-Boost APFC

In this paper, the advantages, working principle, and control principle of CRM-Boost APFC are introduced. Aimed at the shortcomings of the master-slave interleaving control technology, a mutually balanced interleaving control method is proposed based on the optimization of the improved interleaving control method. PSIM software is used to simulate the mutually balanced interleaving control method. The simulation results show that the power factor is up to 99.91% and the input current harmonics are only 1.38%. By comparing the simulation data of the mutually balanced interleaving control method with the improved interleaving control method, it is proved that the mutually balanced interleaving control method has the advantages of accelerating the speed of phase adjustment and recovery, and improving the robustness of phase interleaving.
