Switching strategy for isolated dual‐active‐bridge converter

IET Power Electronics, 2017
The operating characteristics of a dual‐active‐bridge (DAB) converter are generally poor when using the single‐phase‐shift (SPS) control strategy while working with a light load or when the input voltage and the output voltage are not matched with the transformer ratio.
