In　high-power　applications,　integrating　low-voltage　DC　microgrids　into　medium-voltage　DC　distribution　networks　requires　the　use　of　DAB　(Dual　Active　Bridge)　converters　configured　in　an　input-parallel　output-series　ISOP-DAB　system.　Traditionally,　modules　are　interconnected　using　a　voltage-sharing　bus.　This　setup,　combined　with　a　basic　duty　cycle　bus,　regulates　the　system＇s　output　voltage.　It　also　ensures　voltage　equalization　across　all　modules.　However,　failures　in　these　buses　can　compromise　system　performance.　To　address　this　issue,　a　control　strategy　for　input　voltage　sharing　in　ISOP-DAB　system　is　introduced,　leveraging　output　voltage　uplift　characteristics　in　this　paper.　Initially,　the　topology　of　ISOP-DAB　converter　is　analyzed.　Subsequently,　the　operational　principles　of　the　output　voltage　uplift　characteristics　are　detailed.　Finally,　the　effectiveness　of　the　proposed　control　strategy　is　validated　through　experiments　involving　a　system　composed　of　three　DAB　converter　modules.　©　2024　IEEE.
