Igama eliphelele le-i-micro-inverteri-inverter eboshwe ngegridi yelanga encane.Isetshenziswa kakhulu ezinhlelweni zokuphehla amandla e-photovoltaic futhi ngokuvamile ibhekisela kuma-inverter kanye nama-MPPT weleveli yemojuli anesilinganiso samandla esingaphansi kuka-1500W.Ama-Micro-invertersmancane ngosayizi uma kuqhathaniswa nama-inverter amaphakathi.Ama-Micro-invertersguqula imojuli ngayinye ngayinye.Inzuzo ukuthi imojuli ngayinye ingalawulwa ngokuzimela yi-MPPT.Lokhu kuthuthukisa kakhulu ukusebenza kahle jikelele.Ngesikhathi esifanayo,ama-micro-invertersingagwema izinkinga zamandla kagesi aphezulu e-DC, ukukhanya okungekuhle kahle, kanye nomphumela womgqomo wama-inverters amaphakathi.
Ama-Micro-invertersphatha ukuqoqwa kwamandla elanga kumaphaneli ngamanye ukuze kwandiswe ukusebenza kahle kokufakwa kwelanga, kunokuba usebenze kulo lonke uhlelo njengoba i-inverter emaphakathi ingenza.Esikhathini esidlule, izindlela zokulawula eziyinkimbinkimbi ezisetshenziselwa ukuqinisekisa ukusebenza okuphezulu ngesikhathi sokuqoqwa kwelanga ziye zanda izindleko futhi zakhawulela ukutholwa kwama-micro-inverters.Izisombululo zesekethe edidiyelwe kanye ne-processor-based ziyinkimbinkimbi futhi zingabizi kakhulu ukuphatha ukulawula okunengqondoi-micro-inverterimiklamo.Izilawuli kanye nezilawuli zamandla kagesi ezihlukene nazo zihlinzeka ngezixazululo ezihambisanayo zokukhiqiza amandla aphuma ku-DC ophumayo wamaphaneli elanga.
Ngendlela elulai-micro-inverteridizayini, isiguquli se-flyback esibambezelekile esinezimpaphe sithuthukisa amandla kagesi aphansi we-DC asuka kuphaneli yelanga kanye ne-waveform ye-AC kagesi ephezulu edingwa igridi.
Njengomklamo wokuphakelwa kwamandla,i-micro-inverterukuklama kudinga amasu ahlukahlukene ukuze kuthuthukiswe ukusebenza kahle nokwethembeka.Kusetshenziswa i-topology ye-flyback ehlukanisiwe, esiza ukunciphisa i-rms ripple current ngawo, ngaleyo ndlela kwelule impilo yama-electrolytic capacitor kule miklamo.Ukwengeza, ukusetshenziswa kwamasu okubamba asebenzayo kuvumela umjikelezo womsebenzi ophezulu ophezulu, ovumela ukusetshenziswa kwezilinganiso zokujika okuphezulu.Lokhu kunganciphisa kakhulu umthwalo wamanje ohlangothini oluyinhloko kanye nomthwalo we-voltage ohlangothini lwesibili.
Ukuqinisekisa ukuphuma kwamandla aphezulu, i-inverter kumele ikwazi ukuphendula ku-I-micro-inverterukulawula logic.Lokhu kunengqondo kuklanyelwe ukugcina i-voltage kanye namanje kwesiguquli eduze ngangokunokwenzeka kuzici ezifiselekayo ezikhiqizwe i-algorithm ye-MPPT.Okubaluleke nakakhulu, i-grid-ixhunyiweama-micro-inverterskufanele ikwazi ukunqamula kugridi uma kwenzeka ukuphelelwa amandla.Lezi zici zokuvikela amaphutha, nazo, zidinga isiguquli ukuthi okungenani sibe ne-overvoltage kanye nokutholwa kwe-undervoltage.
Umklamo weama-micro-invertersibeka izimfuneko zokulawula, ukuguqulwa kwamandla nokusebenza kahle eziye zakhawulela ukusetshenziswa kwazo okusabalele esikhathini esidlule.Kodwa-ke, ngokusabalala kwezixazululo ezihlanganisiwe, abaklami bangasebenzisa amadivaysi ahlukahlukene afanelekile.Nakuba amaphrosesa azinikele angahlinzeka ngezici zokulawula ezithuthukile kanye nokusebenza kwe-MPPT okudingekayo kuyoama-micro-inverters, amadizayini esiteji sokuguqulwa kwamandla adinga amadivayisi angaletha ngokuphepha nangempumelelo ukusebenza nokusebenza okudingekayo kugridi.Ngohlu olubanzi lwezilawuli zokushintsha ezididiyelwe kanye nama-PMIC atholakalayo, onjiniyela bangakha izigaba zokuguqula amandla ezisebenza kahle, ezibizayo emiklamo ye-inverter encane.
