Theory and Design of the LLC Resonant Converter

Ming Chen

Abstract

This paper analyzes the theory of LLC resonant converter that takes the half-bridge as the main circuit. It also proposes a method that uses the leak-inductance between the primary winding and the second winding as the resonant inductance to design the power transformer. With this method, the LLC converter has been designed and proved to work well by using Li-battery as charger .
