A Study on Power Factor Correction of CO2 Arc Welder Using Three Phase Switch Mode Converter
3상 AC/DC 스위치 모드 승압형 컨버터를 이용한 CO2 아크 용접기 역률개선에 관한 연구
Abstract
In this paper A switched mode AC/DC three phase boost converter with high power factor and sinusoidal input current waveform is analyzed and simulated. The proposed converter retain high power factor and sinusoidal input current waveform even under electric arc welder load. It is shown that experimental result and simulation waveform yield a sinusoidal input current waveform at high power factor.
