Abstract：Three-phase voltage source PWM rectifier with LCL filter on the AC side can suppress harmonics around the switching frequency, and at the same time decrease the inductance dramatically. In this paper, the mathematical model and control algorithm of PWM rectifier with LCL filter are analyzed. Based on the current harmonic restriction of IEEE-519 standard, the parameters of LCL filter are calculated by iterative algorithm with the harmonic voltage of SVPWM. The stability of the system using passive damping is studied in discrete domain. At last, a prototype of 500kW three-phase voltage source PWM rectifier is established. The analysis is validated in experiments.
