To　reduce　the　current　stress　in　the　whole　operating　area　and　improve　the　dynamic　performance　switching　between　different　operating　points　of　the　dual-active-bridge　(DAB)　converter,　a　bidirectional　power　control　(BPC-GCSO)　scheme　based　on　the　global　current　stress　optimization　is　proposed　in　this　paper.　The　global　current　stress　optimal　solution　(GCSO)　set　is　first　derived　for　the　DAB　converter,　which　enables　the　DAB　converter　to　realize　the　minimum　current　stress　at　any　operating　point.　Then,　a　virtual　direct　power　control　method　is　introduced　based　on　the　GCSO　scheme　and　a　bidirectional　power　control　(BPC)　strategy　is　designed.　To　validate　the　proposed　scheme,　a　simulation　experimental　environment　is　built　on　the　MATLAB/Simulink　platform,　and　the　simulation　results　prove　the　feasibility　of　the　proposed　method.　©　2023　IEEE.
