Hebei Provincial Key Laboratory of Power Transmission Equipment Security Defense, North China Electric Power University, Baoding, Hebei, China
The transformer loss is the important factor influencing the transformer operation. The high frequency eddy effects including skin and proximity effects raise the winding losses. The eddy current effects are calculated by the finite element method in consideration of proximity effect and skin effect. The conclusion that changing winding layout can decrease the winding losses is given, and the tendency of the losses caused by skin effect and proximity effect based on different winding thickness, frequency and layer spacing is concluded.
Key words: high-frequency transformer / proximity effect / skin effect / FEM / winding losses
