| Abstract: | According to the operation theory of Power Factor Correction (PFC) Boost Converter, the discrete time map was derived for the average current control PFC Boost Converter. Based on this mathematical model, the fast-scale instability was discovered in PFC Boost Converter with Acc. The consistent conclusion was determined with detail analysis to mathematical model of system and compared with the result form the Simulink exact switching model for PFC Converter. The theory guide to the parameter design for PFC Converter is available based on the correctness of discrete time map for PFC Converters. |
