【 摘 要 】
For the application of high voltage and high power, a three-phase six-module cascade rectifier topology is proposed for high voltage and high power conditions, And analyze this topology from the working principle and control strategy. In order to achieve unity power factor, a control strategy based on carrier phase shift method for reactive power and voltage closed-loop control is proposed. Then the simulation model was built by MATLAB/Simulink. By analyzing the simulation results in detail and by changing the load, the correctness and stability of the proposed control strategy are further verified, it can effectively reduce the harmonics, improve power quality, and achieve unity power factor input and regulated output.
