Input current distortion and output voltage regulation of the boost PFC converter operating with different control methods

Abstract

There are many possible topologies for implementing power factor correction converters. Due to its advantages, the average current control method is one of the most widely used. The critical conduction mode control method is also very used and is employed here for comparison purposes. The main issues to be analyzed in the paper are the input current wave shape and the output voltage regulation. Simulation and experimental results are presented and discussed.
