An ultrasonic series resonant converter with integrated L-C-T

摘要

The concept of an integrated structure for the capacitor, inductor and transformer of the series resonant power converter is presented. It is shown that the necessary capacitance can be achieved by using a bifilar primary and the leakage inductance of the transformer replaces the physical inductor. By integrating three components into one it would be possible to save space, mass, volume and cost.
