A　high-boost　interleaved　DC-DC　converter　that　utilizes　coupled　inductors　and　voltage　multiplier　cells　(VMC)　is　proposed　in　this　paper.　The　input　power　supply　connects　to　switches　through　the　primary　sides　of　two　coupling　inductors　with　an　interleaved　structure,　which　reduces　the　voltage　stresses　of　the　switches　and　lowers　the　input　current　ripple.　Two　capacitors　and　a　diode　are　placed　in　series　on　the　secondary　side　of　the　coupled　inductors　to　enhance　the　high　boost　capability.　The　implementation　of　maximum　power　point　tracking　(MPPT)　is　facilitated　by　the　simplification　of　the　control　system　through　common　ground.　To　verify　the　effectiveness　of　the　proposed　converter,　an　experimental　platform　and　a　prototype　based　on　a　turns　ratio　of　1　are　presented.　The　test　results　show　that　the　voltage　stresses　on　the　switches　are　only　1/8　of　the　output　voltage.　The　operating　principle　and　design　guidelines　of　the　proposed　converter　are　described　in　detail.　The　experimental　results　show　that　the　converter　is　efficient　and　stable　over　a　wide　power　range.　©　2019　Power　System　Protection　and　Control　Press.
