摘要

近年来，直流(DC)电源负载在工业和商业应用中越来越普遍。因此，在系统的前端将放置一个交流/直流转换系统，将交流电源转换为系统运行的直流电源。系统的负载端特性会增加输入交流电源电压和电流之间的相移。这会影响系统的电能质量指标，造成系统不稳定。在需要改善电能质量的ac/dc变换器中，在非控制整流器和负载之间需要功率因数校正变换器。本文对不同的转换器拓扑结构进行了研究和比较。研究了各种转换器拓扑结构的自pfc特性。

A Study on Different Converter Topologies for Power Quality Improvement Applications

In recent years, direct current (DC) power supply loads have become more prevalent in industrial and commercial applications. As a result, an ac/dc converting system will be placed at the system's front end to convert alternating current mains into direct current sources for system operation. Load-end characteristics of the system will increase the phase shift between the voltage and current of the input AC power source. This has a detrimental impact on the system's power quality indicators and causes instability. In an ac/dc converter that needs power quality improvement, a power factor corrector converter is required between the uncontrolled rectifier and the load. Different converter topologies have been investigated and compared in this paper. The self-PFC features of various converter topologies are examined.
