Dzina lonse lamicro-inverterndi inverter yolumikizidwa ndi solar solar.Amagwiritsidwa ntchito makamaka pamakina opanga magetsi a photovoltaic ndipo nthawi zambiri amatanthawuza ma inverters ndi ma MPPT a module omwe ali ndi mphamvu zosakwana 1500W.Micro-invertersndi ochepa kukula kwake poyerekeza ndi ma inverters apakati.Micro-inverterssinthani module iliyonse payekha.Ubwino wake ndikuti gawo lililonse limatha kuyendetsedwa palokha ndi MPPT.Izi kwambiri bwino wonse dzuwa.Nthawi yomweyo,ma micro-invertersamatha kupewa zovuta zamagetsi apamwamba a DC, kuwala kosawoneka bwino, komanso mbiya yama inverters apakati.
Micro-inverterskusamalira kusonkhanitsa mphamvu ya dzuwa pa mapanelo payekha kuwonjezera dzuwa unsembe wa dzuwa, m'malo ntchito kudutsa dongosolo lonse monga chapakati inverter akanatha.M'mbuyomu, njira zowongolera zovuta zomwe zimagwiritsidwa ntchito kuti zitsimikizire kuti magwiridwe antchito apamwamba kwambiri panthawi yosonkhanitsira dzuwa zawonjezera ndalama ndikuchepetsa kutengera kwa ma micro-inverters.Mayankho ophatikizika ndi ma processor onse ndi apamwamba komanso otsika mtengo kuti athe kuwongolera malingaliro amicro-invertermapangidwe.Zowongolera ma voltage osiyanasiyana ndi zowongolera zimaperekanso njira zowonjezera zopangira mphamvu kuchokera ku DC kutulutsa ma solar.
Mwachidulemicro-inverterkapangidwe kake, cholumikizira cholumikizira cholumikizira cholumikizira chimathandizira ma voliyumu otsika a DC kuchokera pagawo la solar komanso mawonekedwe amagetsi apamwamba a AC ofunikira ndi gululi.
Monga kapangidwe ka magetsi,micro-inverterkupanga kumafuna njira zosiyanasiyana kuti zithandizire bwino komanso kudalirika.An interleaved flyback topology imagwiritsidwa ntchito, yomwe imathandizira kuchepetsa ma rms ripple current kudzera mwa iwo, potero kumatalikitsa moyo wa ma electrolytic capacitor pamapangidwe awa.Kuphatikiza apo, kugwiritsa ntchito njira zokhotakhota mwachangu kumathandizira kuti pakhale kuchuluka kwa ntchito, zomwe zimapangitsa kuti azigwiritsa ntchito mosinthana kwambiri.Izi zitha kuchepetsa kwambiri katundu wapano pagawo loyambirira komanso mphamvu yamagetsi kumbali yachiwiri.
Kuonetsetsa kuti pazipita mphamvu linanena bungwe, ndi inverter ayenera kuyankha kuma micro-invertercontrol logic.Lingaliro ili lapangidwa kuti lisunge voteji ndi chapano cha chosinthira kukhala pafupi kwambiri ndi mawonekedwe omwe amafunidwa opangidwa ndi algorithm ya MPPT.Chofunika kwambiri, cholumikizidwa ndi gridima micro-invertersiyenera kutha kutha kulumikizidwa ndi gridi pakagwa mphamvu yamagetsi.Izi zodzitchinjiriza zolakwika, nazonso, zimafuna kuti inverter ikhale ndi ma overvoltage ocheperako komanso kuzindikira kwapang'onopang'ono.
Mapangidwe ama micro-invertersimayika kuwongolera, kutembenuza mphamvu ndi zofunikira zomwe zalepheretsa kugwiritsidwa ntchito kwawo kofala m'mbuyomu.Komabe, ndi kuchuluka kwa mayankho ophatikizika, opanga amatha kugwiritsa ntchito zida zosiyanasiyana zoyenera.Ngakhale mapurosesa odzipatulira atha kupereka zowongolera zapamwamba ndi magwiridwe antchito a MPPT ofunikirama micro-inverters, mapangidwe a siteji yosinthira mphamvu amafuna zipangizo zomwe zingathe kupereka mosamala komanso moyenera magwiridwe antchito ofunikira pa gridi.Pokhala ndi zowongolera zosinthira zophatikizika zophatikizika ndi ma PMIC omwe alipo, mainjiniya amatha kupanga magawo osinthira mphamvu, otsika mtengo pamapangidwe a micro-inverter.
