Studies of a novel AC-DC converter with three-phase power factor correction (PFC)

A novel three-phase major circuit topology is proposed in this paper and its circuit design is also given. Its characteristic is that specific PFC integrated circuit is not applied in this AC-DC converter, there are less circuit components and its power factor is very high. Moreover, its operation principle and power factor correction principle are discussed and analyzed in detail. Its simulation results operating in different duties using MATLAB/SIMULINK are also given. The rationality and correctness of its circuit topology and principle are explained and verified by theory analysis and simulation results.
