Iyini i-Power Inverter?
I-inverter yamandla iyithuluzi eliguqula amandla e-DC (aziwa nangokuthi i-direct current), abe amandla e-AC ajwayelekile (alternating current). Ama-inverter asetshenziselwa ukusebenzisa imishini kagesi kusukela kumandla akhiqizwa yibhethri yemoto noma yesikebhe noma imithombo yamandla avuselelekayo, njengamaphaneli elanga noma ama-wind turbine. Amandla e-DC yilokho amabhethri akugcina, kanti amandla e-AC yilokho iningi lezinto zikagesi ezidingayo ukuze zisebenze ngakho i-inverter iyadingeka ukuguqula amandla abe yindlela esebenzisekayo. Isibonelo, lapho ifoni ixhunywe ku-car cigarette lighter ukuze ishajwe, inikeza amandla e-DC; lokhu kumele kuguqulwe kube amandla e-AC adingekayo yi-power inverter ukuze ishaje ifoni.
Indlela Ama-Inverters Asebenza Ngayo
Amandla e-DC azinzile futhi ayaqhubeka, kanye nokushaja kukagesi okugeleza ohlangothini olulodwa kuphela. Uma ukuphuma kwamandla e-DC kumelelwe kugrafu, umphumela uzoba umugqa oqondile. Amandla e-AC, ngakolunye uhlangothi, ageleza emuva naphambili ngezindlela ezishintshanayo ukuze, uma emelelwe kugrafu, abonakale njengegagasi le-sine, elinama-peaks nama-valleys abushelelezi futhi ajwayelekile. I-inverter yamandla isebenzisa amasekethe kagesi ukuze ibangele ukugeleza kwamandla e-DC kushintshe izinkomba, okwenza kube ukushintshana njengamandla e-AC. Lokhu kuguquguquka kuqinile futhi kuvame ukudala isimo segagasi lesikwele kunesiyingi, ngakho-ke izihlungi ziyadingeka ukuze zilungise igagasi, okuvumela ukuthi lisetshenziswe amadivayisi amaningi kagesi.
Ama-inverter kagesi akhiqiza olunye lwezinhlobo ezintathu zezibonakaliso zamagagasi kagesi.
Isignali ngayinye imele ikhwalithi yokukhishwa kwamandla. Isethi yokuqala yama-inverter enziwe manje asebephelelwe yisikhathi akhiqize isignali ye-Square Wave. Isignali ye-Square Wave ikhiqize amandla angathembekile noma angaguquguquki. Isignali yesibili yamagagasi yi-Modified Square Wave eyaziwa nangokuthi i-Modified Sine Wave. Ama-Modified Square Wave Inverters athandwa kakhulu futhi akhiqiza amandla azinzile asebenzayo angasebenzisa imishini kagesi ejwayelekile. Ama-Pure Sine Wave inverters akhiqiza isignali yamagagasi amandla athembekile futhi angaguquguquki kakhulu. Lokhu kuwenza abize kakhulu ukuwathenga. Eminye imishini ezwelayo njengamathuluzi ashajwayo kanye nemishini yezokwelapha idinga ama-Pure Sine Wave inverters.
Ama-inverter kagesi eza ngezimo ezahlukene kanye namakhono.
Amamodeli avamile amabhokisi amancane angunxande anentambo enamathiselwe kanye nejekhi engaxhunywa echwebeni lokukhanyisa ugwayi kudeshibhodi yemoto. Amanye amamodeli anezintambo ze-jumper ezingaxhunywa ngqo kuma-terminal ebhethri. Ibhokisi ngokuvamile lingaba nezindawo ezimbili zokuxhuma imishini yakho kagesi. Ungasebenzisa i-inverter kagesi emotweni yakho noma esikebheni sakho ukuze unikeze amandla amadivayisi afana nama-laptop, ama-consoles emidlalo yevidiyo, ithelevishini encane noma i-DVD player. Aphinde abe usizo ezimweni eziphuthumayo lapho kuba nokuphazamiseka kukagesi. Futhi ayimithombo yamandla ewusizo ohambweni lokukhempa, emabhishi nasemapaki lapho ugesi ojwayelekile ungatholakali khona. I-inverter kagesi ingasetshenziswa nasezindaweni ezinendawo yokunikezwa kwamandla engazinzile.
I-inverter ixhunywe kumabhethri kanye nomthombo kagesi oyinhloko.
Uma kukhona ugesi kagesi, uhlelo lwenzelwe ukushaja amabhethri ukuze kugcinwe ugesi futhi uma kukhona ukuphazamiseka kukagesi, i-inverter idonsa ugesi we-DC ebhethrini bese iwuguqula ube yi-AC ukuze unikeze amandla ekhaya. Umthamo we-inverter yamandla uzonquma uhlobo nenani lamadivayisi angasetshenziswa ukunikezela amandla. Amamodeli ahlukile ngomthamo we-wattage futhi udinga ukuqiniseka ukuthi uthola i-inverter efanela izidingo zakho.
