A　transient　dc-bias　current　due　to　the　voltage-second　imbalance　of　isolated　bidirectional　dual-active-bridge　(DAB)　converters　for　the　disturbance　in　line　or　load　may　result　in　the　transformer　saturation　and　oscillations　in　both　sides　dc　currents.　This　article　focuses　on　the　transient　dc-bias　current　elimination　by　using　an　improved　triple-phase-shift　(ITPS)　control　for　DAB　converters.　The　inductor　peak　current　stress　optimization　is　adopted　in　the　proposed　ITPS　to　determine　the　steady-state　phase-shift　variables.　Originated　from　the　dc-bias　current　model　of　DAB　converters　with　the　TPS　control,　the　transient　phase-shift　adjustment　strategy　can　be　determined,　which　has　the　ability　to　improve　the　inductor　current　changing　slope　and　shorten　the　settling　time.　Both　simulation　and　experiments　for　different　conditions　are　provided　to　evaluate　main　dynamic　indexes　such　as　the　transient　period,　dc-bias　current,　and　inductor　current　stress　for　three　different　transition　cases.　The　proposed　ITPS　is　proved　as　a　promising　solution　in　eliminating　the　dc-bias　current,　minimizing　the　transient　current　stress.　©　1982-2012　IEEE.
