Abstract :
High frequency effects and Current sharing in paralleled winding at high frequency transformers, witch are using in switch mode power supplies, will discuss in this paper. FEM method is used for simulation and shows that in ordinary paralleling winding, witch is used to decreasing of skin effect, the current is shared unbalance and for perfect paralleling of the winding, interleaved winding must be used. Also, the effect of air gap in the core on the winding current distribution will be scrutinized. And therefore, the experimental results confirm the simulation results.
