Abstract
This paper presents the adoption of PWM converter to enhance input power factor in inverter arc welder. By using PWM converter in inverter arc welder, the disadvantages of bridge diode converter such as low input power factor is improved, new NCT(Noise Cut Transformer) is designed to reduce noise which has harmful effect in switching component, half bridge PWM inverter is adopted to reduce cost in inverter arc welder.
