| Abstract: | In this paper, the model of three-level PWM rectifier is set up and the fundamental principle of three- level space vector pulse-width modulation is analyzed based on fundamental topological structure of three-level neutral point clamped PWM rectifier. An ameliorated feedforward control strategy and a simplified algorithm are proposed. The control system is simulated by using MATLAB/Simulink. The simulation results demonstrate that the proposed feedforward control strategy and the simplified algorithm are feasible, and the system has excellent performance both in steady and dynamic states. |
