To　address　the　problem　of　insufficient　boost　capability　of　the　conventional　Boost　converter，this　paper　proposes　a　novel　non-isolated　boost　DC-DC　converter，which　features　high　voltage　gain，continuous　input　current，low　voltage　stress　on　the　switch　and　diodes，and　high　efficiency.　By　introducing　coupled　inductors　in　the　circuit，the　circuit　can　operate　at　a　proper　duty　cycle　D　while　maintaining　the　voltage　gain　by　adjusting　the　turn　ratio.　The　paper　begins　with　an　analysis　of　the　operating　state　of　the　proposed　converter.　Then　the　voltage　and　current　stresses　of　the　components　are　deduced.　Furthermore，to　highlight　the　performance　advantages　of　the　proposed　converter，it　is　compared　with　other　topologies.　Finally，the　feasibility　and　effectiveness　of　the　proposed　converter　are　verified　by　an　experimental　prototype　fabricated　in　the　laboratory.　©　2024　Science　Press.　All　rights　reserved.
