| Abstract: | This paper presents an analysis of the work process of a PS-FB-ZVZCS PWM DC/DC converter with saturated inductor and proposes the design principle of several key parameters. The converter is simple and efficient, and the lagging-leg as well as the leading-leg can achieve soft switch in a very broad range of loads. A 250 A/10 kW experimental weld machine is built to prove the efficiency and reliability of the design principle. |
