description: This study aims at development and research of a medium frequency flash butt welding transformer. We investigate the influence of leakage inductance on the transient time of the welding current of the invertor machine using Microcap package and skin effect in Bosch PSG 3050.10A medium-frequency transformer by using 2D finite element method. High skin effect was observed in the primary winding. To reduce the skin effect, three methods were used. Changing the position of interleaving primary and secondary winding which reduced the losses by 20,6%, reducing the characteristic size of primary winding wire reduced the losses by 6,5% and increasing the number of primary winding sections decreased losses by 32% compared to PSG 3050.10A. Therefore, a new design transformer has been proposed in which the skin effect is less than in PSG 3050.10A by 44,8%.
