| Abstract |
This study presents the results of the research on power supplies for welding machine using MOSFET switches in high frequency switching for ease of design and use a 100 kHz switching frequency for high power density. The topology of the proposed power supplies for welding machine is ZVS-PWM full-bridge converter. The proposed converter is designed on a distributed transformer for ease of design and be used in a 100 kHz switching frequency for high power density. The problem of power imbalance of transformers occurring in parallel operation of transformers can be improved by applying common mode coupled inductor and the corresponding contents are experimented and verified in this paper to present conclusions. |
