Abstract

This paper presents the design and analysis of a LLC resonant converter with an integrated transformer. The leakage inductance of the transformer participates in the resonance. No additional series resonant inductance is introduced. The novelty consists in designing the transformer around the value of the leakage inductance. A new method of obtaining a desired value of the leakage inductance is explained. Theory is validated by simulation and experimental results, which are in good agreement
