摘要

To reduce parasitic capacitance between primary and secondary windings.SOLUTION: A transformer includes a central magnetic leg wound with a primary winding and multiple external magnetic legs wound with secondary windings respectively, and the external magnetic legs are equal in the cross-sectional areas to each other and are equally distanced from the central portion of the central magnetic leg, and are arranged such that the distances between adjacent external magnetic legs are equal, and the cross-sectional area of the central magnetic leg is equal to the sum of the cross-sectional areas of the respective external magnetic legs.SELECTED DRAWING: Figure 1
