Research on Three-Phase PWM Rectifiers Applied in Small Wind Power System

LI Lin-jie

Abstract

A small wind power system generally consists of a diode rectifier and a Boost DC/DC converter.Aimed at improving the power generation efficiency and overcoming the system disadvantages,a three-phase PWM rectifier was applied instead of uncontrol rectifier and Boost converter.The work principle and key control method were analyzed and studied,using the TMS320F2812 as control processor for PWM signal generating.Finally,the system model was simulated by Matlab/Simulink,and the results prove the feasibility and the advantages.
