Embodiment Construction
[0030] Various embodiments of the present invention are described with reference to the above-mentioned drawings.
[0031] A method for solving electromagnetic interference of a switching power supply transformer when there is no Y capacitor, the method comprises the following steps:
[0032] A. Choose a magnetic core;
[0033] B. Wind the primary winding on the magnetic core;
[0034] C. Winding secondary windings and additional windings;
[0035] D. transformer oil immersion; described step B is divided into following sub-steps:
[0036] B 1 . At least one layer of shielding winding is densely wound on the magnetic core, and one end of it is suspended in the air;
[0037] B 2 . the shield winding is covered with at least one insulating layer;
[0038] B 3 .A primary winding of 130 to 160 turns is wound outside the above insulation layer. After one layer of primary winding is wound, at least one layer of insulation layer is covered, and then the next layer is wound, an...
