摘要： A three-phase rectification module, the system thereof and harmonic suppression method are provided. The module includes an LCL filter unit, a Vienna rectifier coupled to the LCL filter unit, and a rectifier control unit for controlling the power factor of the three-phase AC power source and the DC output voltage of the Vienna rectifier. A commutation diode is serially connected on the bridge-arm of each set of uni-directional rectification branches which are included in the Vienna rectifier, making it function as current uni-directionally. Herein, the power factor of the three-phase AC power source is matched with the parameters of the LCL filter unit, such that the absolute value of the phase difference between the AC input voltage and the current of the Vienna rectifier is close or equal to zero.
