CORE FOR ORTHOGONAL TRANSFORMER AND ORTHOGONAL TRANSFORMER COMPOSED THEREOF

摘要

PURPOSE: To reduce the thickness of an orthogonal transformer by providing a pair of protruded sections having a prescribed width and length on the side face of one side leg of a Ushaped core opposite to the side face of the side leg facing the other side leg of the core in parallel with the extending direction of the side leg. ;CONSTITUTION: An orthogonal transformer is constituted of one first bobbin 3 for control winding, four cores 7, and one second bobbin 10 for main winding. The ferrite core of the transformer is constituted by combining the cores 7 respectively having protruded sections 5 protruded in the longitudinal direction with a center leg 6. The first bobbin 3 is composed of a core 1 and flanges 2 and put on the protruded section 5 of the center leg 6 of the core 7. The second bobbin 10 is composed of a core 8 and flanges 9 and put on the center leg 6. Therefore, this transformer can have the same thickness as that of the conventional. transformer using an E-shaped core and the same characteristics as those the conventional orthogonal transformer using a U-shaped core has.;COPYRIGHT: (C)1995,JPO
