| Abstract: | This paper derives a kind of soft-switched PWM technique from the benefits of both the soft-switched quasi-resonant converter and pulse-width-modulated (PWM) techniques by utilizing PWM phase-shifted control, and which is applied to inverter for arc welder. The paper introduces the configuration, principle and characteristics of the inverter for arc welder. |
