AN ULTRASONIC SERIES RESONANT CONVERTER WITH INTEGRATED L-C-T

The concept of an integrated structure for the capacitor, inductor and transformer of the series resonant converter is presented. It is show n that the necessary capacitance can be achieved by using a bifilar pr imary and the leakage inductance of the transformer replaces the physi cal inductor. By integrating three components into one it would be pos sible to save space, mass, volume and cost.
