Design of Resonant DC-DC LLC converter

Kali Naraharisetti, Janamejaya Channegowda, Peter B. Green

Abstract

The paper discusses the design of LLC resonant converter which provides high efficiency and high power density. The prototype designed in this paper is an LLC resonant converter and the paper goes into a detailed design and modelling of the LLC stage converter. The LLC resonant converter operates as a variable frequency converter. The design achieves an efficiency greater than 90 percent meeting several international standards for high efficiency. The results of the prototype design have also been verified using Simplis. The stability of the power supply has been verified using a frequency response analyzer.
