Low-alternating-current copper loss planar magnetic part winding for power electronic converter

The invention discloses a planar magnetic part winding with low alternating current copper loss for a power electronic converter. The planar magnetic part winding comprises a magnetic core and a winding, the magnetic core is provided with a cavity, the winding is formed by horizontally surrounding a planar winding sheet, and the winding is arranged in the cavity; a plurality of layers of plane winding sheets are arranged in the winding, the layer closest to the zero magnetomotive force position serves as the first layer of winding, and the layer numbers of the winding are gradually increased in sequence as the winding layer is far away from the zero magnetomotive force position; the number of turns of the nth layer of winding is greater than or equal to the number of turns of the mth layer of winding. According to the invention, the loss caused by the proximity effect between the windings can be reduced, so that the alternating-current copper loss of the magnetic part is reduced. 本发明公开一种用于电力电子变换器的带低交流铜损平面磁件绕组
