Abstract
A cost effective integrated automotive solution for a charger transformer with minimized fringing flux and core grounding for reducing electromagnetic interference (EMI). The method provides an air gap filled with a mixture of an adhesive and ferrite powder that bonds the ferrite core sections together. In addition, the ground pin of the transformer is exposed through a groove in the pocket of the bobbin on which the core is mounted and an electrical contact is established between the exposed end of the ground pin and the core surface by means of a drop of epoxy.
