Izilawuli zokushaja kwelanga noma izilawuli ziyizinto ezisetshenziswa ezibanini ezisebenzisa amandla elanga ukulawula ugesi ogeleza usuka kuphaneli yelanga uye ebhethrini. Izilawuli zelanga nazo zinesibopho sokunciphisa ugesi odonswa ebhethri uye ku-LED. Ohlelweni lokukhanyisa kwelanga, izilawuli zidlala indima ebalulekile ekuphatheni ukushaja kanye ne-voltage. Lapho amaphaneli elanga eyeka ukukhiqiza amandla ekushoneni kwelanga, izilawuli ziyasiza ekuphenduleni i-LED.
Kukhona ithuba lokuthi ugesi ugeleze usuka ebhethrini uye kumaphaneli uma kungekho ugesi okhiqizwa ebusuku, okungalimaza impilo yamabhethri. Abalawuli bokushaja basiza ekuvimbeleni lokhu kugeleza kwamandla okubuyela emuva ngokuthola lapho kungekho ugesi okhiqizwayo nokunqamula amaphaneli kumabhethri ukuze kugwenywe ukushaja ngokweqile. Ukushaja ngokweqile kunganciphisa nokuphila kwamabhethri futhi abalawuli bokushaja banamuhla basiza ekwandiseni impilo yebhethri ngokunciphisa inani logesi osetshenziswa ebhethrini uma selishajwe ngokugcwele futhi kusize nasekuguquleni i-voltage eyengeziwe ibe yi-amperage.
Kungani kudingeka abalawuli ezibanini zelanga?
●Ukulawula i-voltage yebhethri
●Ukuvimbela ukugeleza kwamanje okuphambene
●Ukugwema ukushaja ngokweqile nokushaja kancane kwamabhethri
●Ukukhombisa ukuthi ibhethri lishajwa nini
Izinhlobo zezilawuli zokushaja zelanga
Izilawuli zokushaja ze-Pulse Width Modulation (PWM)
I-PWM iyisilawuli esisetshenziswa kakhulu njengoba isebenzisa ubuchwepheshe obuvivinywe isikhathi eside ukulawula ukugeleza kwamandla kagesi. Ukuguquguquka kobubanzi be-pulse kwenzeka lapho ibhethri lifinyelela esigabeni sokushaja esilinganiselayo ngokunciphisa amandla kagesi kancane kancane. Ukuzikhipha kuyinkinga evamile kumabhethri amaningi ashajwayo lapho evame ukulahlekelwa amandla uma eseshajwe ngokugcwele. Isilawuli se-PWM siqala kabusha ukunikeza amandla amancane njalo ukuze sigcine ibhethri ligcwele futhi ligcine ishaja, ngaleyo ndlela sigweme ukuzikhipha.
Izilawuli ze-PWM zibhekwa njengeziqinile kakhulu futhi zisebenza kahle ezindaweni ezifudumele. Zishibhile kakhulu futhi zitholakala ngobukhulu obuhlukahlukene ngezinhlelo ezahlukene zokusebenza. Ngezilawuli ze-PWM, kubalulekile ukuba namaphaneli elanga namabhethri ane-voltage efanayo. Isilawuli sokushaja se-PWM siyisilawuli sokushaja sohlobo olujwayelekile esisetshenziswa ekukhanyeni komgwaqo welanga futhi sifanelekile nasezinhlelweni ezincane zelanga ezinamaphaneli amancane nebhethri.
Izilawuli zokushaja ze-Maximum power point tracking (MPPT)
Izilawuli ze-MPPT ziyindlela ebiza kakhulu futhi eyinkimbinkimbi yezinhlelo zelanga; nokho, enye yezinzuzo ezinkulu zalezi zilawuli ayifani nezilawuli ze-PWM, izilawuli ze-MPPT zingalinganisa ama-voltage angalingani avela kumaphaneli elanga namabhethri. Indlela esetshenziswa kubalawuli be-MPPT intsha evumela amaphaneli ukuthi asebenze endaweni yawo yamandla ephezulu. Ngenxa yezinga elihlukile lemisebe yelanga usuku lonke, i-voltage yephaneli kanye nogesi kungahluka. Izilawuli ze-MPPT zilungisa i-voltage ukuze zikhiqize amandla aphezulu kungakhathaliseki ukuthi isimo sezulu siyini.
Abalawuli be-MPPT bashaja ngokushesha futhi baphila isikhathi eside. Bayakwazi ukulungisa okokufaka kwabo ukuze baqalise amandla aphezulu ngangokunokwenzeka kusuka kumaphaneli. Laba balawuli bayakwazi ukushintsha amandla okukhipha ukuze afane namandla ebhethri. Babonakala besebenza kangcono ezindaweni ezibandayo futhi babhekwa njengabasebenza kahle kakhulu kunabalawuli be-PWM.
Ungakhetha kanjani isilawuli sokushaja esifanele?
Zombili izilawuli zokushaja ze-PWM kanye ne-MPPT zisetshenziswa ohlelweni lokukhanya komgwaqo olusebenzisa ilanga. Izilawuli zisebenza njengedivayisi yokuvikela futhi zikhipha okungcono kakhulu kuyunithi yakho yelanga. Ngokusekelwe kulezi zici ezilandelayo, kufanele ukhethe isilawuli esihambisana ne-voltage yesistimu yakho yelanga.
Isikhathi sokuphila sesilawuli
Indawo yokufakwa kanye nezimo zokushisa kwayo
Izidingo zakho zamandla kanye nesabelomali
Ukusebenza kahle kwamaphaneli elanga
Usayizi ophelele wohlelo lokukhanya kwelanga
Uhlobo lwebhethri olusetshenziswa ohlelweni lokukhanya kwelanga
Njengoba kuboniswe esithombeni, i-Zenith Lighting ingumkhiqizi ochwepheshe wazo zonke izinhlobo zezibani zasemgwaqweni, uma unemibuzo noma iphrojekthi, sicela ungangabazi ukuxhumana nathi.
