In　the　application　of　the　visible　light　communication　between　small　satellites　for　independent　photovoltaic　power　generation　system,　a　resonant　three-port　LED　driver　was　proposed.　The　steady　state　characteristics　of　the　proposed　driver　and　the　key　parameter　were　theoretically　derived　and　analyzed.　Combined　with　the　proposed　driver,　a　control　strategy　incorporating　variable　pulse　position　modulation　(VPPM)　of　visible　light　communication　modulation　with　power　conversion　LED　driver　was　proposed,　which　the　position　of　the　output　pulse　current　was　utilized　to　realize　data　transmission,　and　the　brightness　adjustment　required　for　communication　was　completed　by　adjusting　the　width　of　the　output　pulse　current,　which　is　used　to　be　suitable　for　longer　distance　VLC　modulation,　and　the　output　average　current　for　lighting　can　be　controlled　to　be　constant.　The　control　principle　and　control　process　were　analyzed　in　detail.　The　computer　simulation　was　carried　out.　An　experimental　prototype　of　the　proposed　driver　and　its　hybrid　control　strategy　with　a　rated　output　of　0.　6　A　/　20　W　was　designed　and　set　up,　with　an　efficiency　of　up　to　95.　6%,　and　a　data　transmission　rate　of　10　kbps-20　kbps.　The　simulation　and　experimental　results　have　been　obtained　to　verify　the　proposed　resonant　three-port　LED　driver　and　its　hybrid　control　strategy.　©　2024　Editorial　Department　of　Electric　Machines　and　Control.　All　rights　reserved.
