Popis:	This paper proposes a buck-type harmonic injection three-phase rectifier to mitigate the high voltage stress of the rear switch of the conventional boost-type power factor correction (PFC) circuit. It develops a control strategy composed of improved double loop control pattern and voltage feedforward pattern. Firstly, the working principle of the buck-type harmonic injection three-phase rectifier is described. Then, it demonstrates the advantage of improved control strategy. Afterwards, the controller's corresponding involved parameters are optimized. Finally the theoretical analysis and simulation results show that the circuit can output the stable low ripple voltage with increased power factor and decrease the harmonic content of input side current.
