This article proposes a dynamic modeling and control approach for dual active bridge converters, which have attracted significant attention for its merits of bi-directional power flow and soft switching capability. Due to the non-linear nature of dual active bridges, the techniques of averaging and linearization are utilized to derive the small-signal model. The affine parameterization is then presented for designing the closed-loop system to regulate the output voltage. The effectiveness of the modeling process and closed-loop regulation is verified by experimental evaluation.
