Abstract

In recent years, A PWM Converter or Switched Mode Converter with high power factor and sinusoidal input current have got widespread studied. But, Almost all of studies is based on linear load. This paper reports on research aimed at achieving high power factor and sinusoidal input current waveform for electronic arc welder, which has nonlinear dynamic characteristics. It is shown that simulation result yield its property.
