Small-signal Model for Dual-active-bridge Converter Considering Total Elimination of Reactive Current

Emerging technologies such as electric vehicles, sol-id-state transformers, and DC transformers are implemented using the closed-loop bi-directional dual-active-bridge (DAB) converter. In this context, it is necessary to have average models that provide an efficient way of tuning the proportional integral (PI) compensator parameters for large- and small-signal applications. We present a novel smal...
