With　the　consumption　of　fossil　fuels,　new　energy　is　increasingly　being　applied,　with　wind　and　solar　energy　being　typical　representatives.　Due　to　its　simple　structure,　multi　input　DC　converters　have　become　an　increasingly　important　part　of　multi　energy　joint　power　supply　systems,　replacing　multiple　single　input　DC　converters.　Therefore,　this　paper　proposes　a　dual　input　Cuk　converter,　and　provides　a　detailed　analysis　of　its　working　principle　and　performance　characteristics.　Finally,　it　is　verified　through　computer　simulation.　The　results　indicate　that　the　circuit　can　achieve　collaborative　power　supply　between　two　power　sources,　ensuring　stable　output　voltage　and　improving　system　stability　and　flexibility.　©　2024　IEEE.
