Asymmetric Operation of DAB Converter with Reduced Conduction Devices for Energy Storage Applications

Year: 2025

Type: article

Abstract: This paper proposes an asymmetric operation of dual active bridge (DAB) bidirectional converter by reducing the conduction devices count which improves the operating efficiency. It also offers the advantages of elimination of circulating power flow (CPF), extension of soft switching region, reduction in current stress and smaller filter requirement. The paper describes the detailed operating waveforms and analysis of power transfer for the proposed asymmetric operation of the DAB converter. To analyze the accurate power dissipation in each power component the loss breakdown analysis is presented. The analytical results presented in this paper and proposed operation of the DAB converter has been verified through the experimental results.
