This paper presents a systematic design methodology for a Dual Active Bridge (DAB) converter. The proposed method applies a Pareto optimization to simultaneously address multiple objectives, including both RMS and switching losses. Furthermore, this approach can perform optimization that balances nominal and worst-case operating points to ensure high efficiency and robustness. The proposed design process is validated with experimental results with 7.3kW/400V prototypes.
