摘要

三相大功率整流技术已经广泛用于电机拖动、大功率AC-DC电源变换中。谐波含量多、功率因数不高是大功率整流电路的普遍问题。随着对绿色电源的呼声日益高涨

减少谐波电流对电网的干扰显得越来越重要。采用高频PWM整流可以有效调节输出电压

使输入电流近似于正弦波

但其成本高

且开关损耗大

效率不高

特别是在中、高功率场合

缺点更加明显。在大功率整流器领域

通常采用多相整流技术。笔者首先介绍了多脉波整流变压器移相的实现以及延边三角形电压、移相角及匝数的计算方法

接着分析了基于此变压器的24脉波整流器的工作原理及特性

并利用MATLAB/SIMULINK仿真验证了其有效性。

Abstract

Three-phase high-power rectifier has applied to electromotor and high-power AC-DC transformation widely

but there are many problems such as harmonics and low power factor.As much more requests of green electrical source

it is more and more important to reduce its disturbance to electrical network.High-frequency PWM rectifier can adjust output voltage and make current near to sine wave efficiently

but there are disadvantages as high cost

high switch cost and low efficiency especially in high-power field

in which multi-pulse rectifier is used widely.This paper introduces the realization of phase-shifting of the multi-pulse converter transformer and the methods for calculating stretch triangle voltage

phase-shifting angle and the number of windings.Then the 24-pluse rectification system based on this transformer is analyzed and simulated.The experiment results verify its feasibility.
