Abstract
An embedded core electrical transformer () for DC to DC current conversion at a switching frequency of 1 MHz has reduced volume and weight with increased power density. The electrical transformer () utilizes a plurality of conductive elements () disposed inside a hollow cavity () used to embed two magnetic cores (). The conductive elements () encircle three sides of the embedded cores () and interface with a multilayer PCB () which includes conductive traces formed therein to encircle a fourth side of the embedded cores and to form primary and secondary winding circuits.
