Abstract:

By the analysis of three phase three switch three level (Vienna) rectifier principle,one-cycle control method of the rectifier is studied,and the outer inner voltage-current dual closed loop control system is adopted,and reliability and stability and low harmonic distortion characteristics of the Vienna rectifier are realized.The Vienna rectifier simulation model is set based on Matlab simulation platform,and the simulation results show that the 8 kW three-phase PFC rectifier based on one-cycle control method has simple control structure,high reliability and stability with a harmonic distortion rate less than 3% and a power factor up to 99%.

Key words: Vienna rectification;one cycle control;RS flip-flop;power factor
