This　work　proposes　a　triple　phase-shift　(TPS)　control　for　a　dual　active　bridge　(DAB)　DC-DC　converter　with　reconfigurable　transformer　(RTDAB)　to　improve　its　efficiency　over　a　wide　voltage　range.　By　optimizing　the　inductor　rms　current　of　the　RTDAB　under　TPS　control　in　different　working　modes,　the　proposed　control　method　can　achieve　a　lower　rms　current　under　a　wide　voltage　range.　The　proposed　control　method　is　obtained　on　the　basis　of　the　traditional　TPS　control　of　DAB　converter　and　does　not　require　complicated　mathematical　processing.　The　control　approach　is　easy　to　implement.　Finally,　simulation　results　on　the　MATLAB/Simulink　platform　demonstrate　the　efficiency　of　the　suggested　strategy.　　©　2024　IEEE.
