| Abstract: | Based on mapping and simulating magnetic characteristic curve of arc welding transformer with high leakage flux, magnetizing inrush current has been calculated under variable conditions. The effects of the point on voltage wave, the remanent flux density, the primary winding resistance and leakage inductance on the magnetizing inrush current have also been presented. Finally, some measures to reduce magnetizing inrush current have been introduced. |
