Optimal Design of a Dual-Active-Bridge DC–DC Converter
IEEE Transactions on Industrial Electronics, 2021This article presents a systematic design procedure for a dual-active-bridge (DAB) dc–dc converter. Design of a DAB converter involves determination of two key parameters, i.e., transformer turns ratio and the series inductance value. Existing literature addresses this problem through numerical optimization, which is computation intensive and does not ...
