Abstract

This study deals with the design and simulation of an enhanced PFC system for a front-end three-phase rectifier based on current injection utilized for gas metal arc welder. Compared with traditional arc welding machines, the suggested arc welding power source (AWPS) is the best choice for its benefits such as simple circuit, superior energy productivity, and capability to achieve unity PF with good weld bead quality and best arc stability. The proposed welding system is designed to function under a variety of load power while enhancing the efficiency of AWPS and power quality (PQ) in AC mains. A closed-loop fractional PI control system with one voltage detector is used to realize voltage and arc current controls with fast response. MATLAB program was exploited to simulate the suggested AWPS and the performance of studied system is examined with that of a Diode Bridge Rectifier (DBR). The suggested structure offers a high PF and a significant decrease in input current THD under rated load conditions.

主动注入电流的焊接电源PFC系统的设计与分析

本文研究了一种用于气体金属弧焊机的基于电流注入的前端三相整流器的增强型PFC系统的设计与仿真。与传统弧焊机相比，建议的弧焊电源(AWPS)具有电路简单，能量生产率高，能够实现统一PF，焊头质量好，电弧稳定性好等优点，是最佳选择。所提出的焊接系统可在各种负载下工作，同时提高交流市电AWPS的效率和电能质量(PQ)。采用一个电压检测器的闭环分数PI控制系统，实现了对电压和电弧电流的快速响应控制。利用MATLAB程序对所提出的AWPS进行了仿真，并与二极管桥式整流器(DBR)的性能进行了比较。在额定负载条件下，建议的结构提供高PF和显著降低输入电流THD。
