    • Abstract
  • In view of characteristics of less output harmonics, low distortion rate of current and suitable for development of high-voltage and large capacity, the paper proposed a design scheme of three-phase three-level PWM rectifier based on double closed-loop control. It analyzed principle of main circuit and building of mathematical model of the rectifier, introduced implementation of control strategies of double closed-loop with voltage loop and current loop and neutral-point voltage balance in details. The simulation result of Matlab/Simulink shows that the rectifier has good dynamic and stable performances.
