Title:
TRANSFORMER
Document Type and Number:
Japanese Patent JP3223425
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a transformer in which stray capacitance and leakage inductance can be decreased.
SOLUTION: A first group of conductive patterns a1-a5 constituting the primary winding of a transformer and a second group of conductive patterns b1-b5 constituting the secondary winding of the transformer are formed on an insulator 1. The conductive patterns a1-a5 and b1-b5 are formed respectively in a loop shape with an opening, and are arranged in the direction from the center to the outer periphery on the insulator 1. By suitably connecting each other among the conductive patterns a1-a5 of the group 1 and among the conductive patterns b1-b5, with connecting patterns c1-c5 or the like, each winding of the transformer is constructed, and the winding ratio between each winding is set at a specified value.
