Under the conventional phase shift control, the dual active bridge (DAB) converter will create a significant amount of backflow power. Due to the various specifications of each module, there will be an unequal distribution of power in the input series output parallel system. This study suggests a power balancing technique based on master-slave independent control to address the aforementioned issues. This strategy assures the power balance of each DAB module and optimizes the backflow power of each module under various operating situations. Finally, an analysis and verification are performed on the input series output parallel (ISOP) system made up of three DAB converters.
