Parameters Design and Simulation Verification of Boost Power Factor Correction Converter with One-cycle Control Method

Power factor correction(PFC) converters based on one-cycle control method have the advantages of simple circuit andhigh response speed, which have become a hot research topic in switching power supplies. First, the working principle of the one-cycle control Boost PFC converter is analyzed. Then, parameters design for the Boost PFC converter based on IR1155 S controlleris realized. Final, simulation verification is implemented with Saber software package. Results indicate that the one-cycle controlmethod can reduce the complexity of the PFC converter and achieve good results in power factor correction. It has a good applica-tion prospect in single-phase high power switching supply.
