Voltage conversion method, electronic equipment, planar transformer and winding structure thereof

The invention provides a voltage conversion method, electronic equipment, a planar transformer and a winding structure thereof, a first winding and a second winding of the planar transformer are arranged in a cavity of a magnetic core, and N turns of first coils of the first winding are arranged on the upper side, the lower side, the left side and the right side of M turns of second coils of the second winding, when currents with opposite directions flow through the first winding and the second winding, the magnetic fields of the first coil and the second coil can offset each other, so that the magnetic field intensity of the first winding and the second winding in multiple directions in the planar transformer can be reduced, and the eddy current loss of the planar transformer is further reduced. 本申请提供一种电压变换方法、电子设备、平面变压器及其绕组结构，将平面变压器的第一绕组和第二绕组设置在磁芯的空腔内，并将第一绕组的N匝第一线圈，设置在第二绕组的M匝第二线圈的上、下两侧和左、右两侧，当第一绕组和第二绕组内流经方向相反的电流时，第一线圈和第二线圈的磁场能够相互抵消，从而能够减少了平面变压器内第一绕组和第二绕组在多个方向上的磁场强度，进而减少了平面变压器的涡流损耗。
