Abstract

This paper describe the step down three phase ac/dc converter involving a simple topology of 6 ideal switches using MATLAB/SIMULINK simulation model. This project consists of two parts. First part is ac-to-dc converter and the second parts are consisting of buck converter. In this project use the fast control strategy of three phases ac/dc by pulse-width modulation (PWM) converter and the input current is regulated to be sinusoidal and the source power factor can be controlled at unity. This project considered the total harmonic distortion (THD) which was defined as the power summation ratio of all harmonic components to the fundamental frequency power. The result of MATLAB/SIMULINK was analysed at the end of this paper/project.
降压三相变换器
本文用MATLAB/SIMULINK仿真模型描述了涉及6个理想开关的简单拓扑的降压三相ac/dc变换器。本项目由两部分组成。第一部分为交直流变换器,第二部分为降压变换器。本课题采用脉宽调制(PWM)变换器的三相交/直流快速控制策略,将输入电流调节为正弦波,源功率因数可控制为1。本课题考虑总谐波失真(THD),其定义为所有谐波分量与基频功率的功率之和之比。本文最后对MATLAB/SIMULINK的结果进行了分析。
