Performance Comparison of Dual Active Bridge Conventional and Dual Active Bridge CLLC Resonant Converter

Abstract

This paper presents a comparative analysis of the performance between dual active bridge (DAB) conventional converter and dual active bridge CLLC resonant converter for energy storage applications. The DAB resonant converter topology has gained significant attention due to its high efficiency, reduced size, and improved reliability compared to conventional converter topologies. In this paper, the performances of DAB conventional converter and DAB CLLC resonant converter on same control and modulation technique under various operating load have been evaluated. The study focuses on design of converters for an output power of 500 W, an input DC link voltage of 200 V, and an output voltage range of 60-84 V. © 2024 IEEE.
