Modeling and Minimization of Switching Loss in Dual Active Bridge Converters

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
This paper presents a closed-form formulation to model the switching loss in single-phase dual active bridge converters (DAB). The proposed model is general and covers all modulation techniques with one, two, or three control parameters. Moreover, in this paper, the switching loss is minimized in a DAB converter controlled by the extended phase shift ...
