摘要
在需要采用三相整流器的中大功率场合，可控或不可控整流电路产生的低功率因数高谐波含量电网电流导致了电网电压畸变，增加了配电系统导体、变压器损耗和中线谐波电流。随着电力电子技术的发展，有功率因数校正的三相整流器越来越受到人们的重视。
The low power factor and large harmonic line currents generated by controlled and uncontrolled rectifiers can lead to line voltage distortion, increasing losses in conductors and transformers of the distribution network, and increasing harmonic currents in neutral lines. For medium to high power applications three phase rectifiers are used. With the deve lopment of power electronics, three phase rectifiers with power factor correction are recently gaining more attention. The objective of this paper is to introduce the evolution of three phase rectifiers with high power factor.
