Esimweni sanamuhla sezobuchwepheshe esithuthuka ngokushesha, isidingo sikagesi asikaze sibe sikhulu.Njengoba ukusetshenziswa kwezinto ze-elekthronikhi kuqhubeka nokwanda kanye nokusebenza kwezimboni kwanda, ikhwalithi yamandla isiphenduke into ebalulekile emabhizinisini nasezinsizeni.Lapha kulaphoizihlungi ezisebenzayo ezifakwe kwikhabhinethi ziyezaokusebenzayo, ukuhlinzeka ngesixazululo esinokwethenjelwa, esisebenza kahle sokunciphisa ukuvumelana, ukuthuthukisa isici samandla kanye nokuqinisekisa ukuhlinzekwa kukagesi ozinzile nokuhlanzekile.
Izihlungi ezisebenzayo ezifakwe kwiKhabhinethi ziyizingxenye ezibalulekile ezinhlelweni zokusabalalisa amandla futhi zenzelwe ukuhlinzeka ukusebenza okuphezulu ekuqedeni ukuhlanekezela okuvumelanayo kanye nokwenza ngcono izinga lamandla.Le divayisi emisha ixhunywe kugridi yamandla ngokuhambisana futhi ithola amandla kagesi kanye namandla ento yesinxephezelo ngesikhathi sangempela.Ngobuchwepheshe bekhompiyutha obuthuthukisiwe nokulawula, ikhiqiza ngempumelelo i-reverse-phase, ama-amplitude alinganayo ukuze asuse ama-harmonic currents akhona kugridi yamandla.Lokhu kuqeda ama-harmonics angafuneki, kuthuthukisa kakhulu ikhwalithi yamandla.
Inhliziyo yesihlungi esisebenzayo esifakwe kwikhabhinethi iyiyunithi yokusebenza yamanje yomyalo, edlala indima ebalulekile ekuxhumaniseni imisebenzi yayo eguquguqukayo.Ubuchwepheshe bokuguqula isignali yokushintshashintsha kwe-pulse ebanzi busetshenziselwa ukushayela imojuli ephansi ye-IGBT nokufaka okwamanje okukhiqiziwe kugridi yamandla.Ngakho-ke, ama-harmonics ahlukaniswa ngokuphumelelayo, okuqinisekisa ukuthi amandla anikezwe kumthwalo oxhunyiwe awahlanekezelwe futhi aguquguquke.Lokhu kunemba nokuphendula kwenza izihlungi ezisebenzayo ezifakwe ekhabetheni zibe ithuluzi elibalulekile ekugcineni ikhwalithi yamandla esezingeni eliphezulu ezinhlelweni zokusebenza ezihlukahlukene.
Njengoba abantu benaka kakhulu ukuvikelwa kwemvelo kanye nezinqubo ezisimeme, indima yezihlungi ezisebenzayo zohlobo lwekhabhinethi ekwehliseni ukusetshenziswa kwamandla kanye nokwenza ngcono ukusebenza kahle akukwazi ukubukelwa phansi.Ngokususa ama-harmonics namandla asebenzayo, lezi zihlungi azithuthukisi ikhwalithi yamandla kuphela kodwa futhi zisiza ukwehlisa ukulahleka kwamandla kanye nezindleko zokusebenza zizonke.Lokhu kubenza babe utshalomali olukhangayo kumabhizinisi abheke ukuthuthukisa ukusebenza kwesistimu yokusabalalisa kuyilapho ethobela izindinganiso nemithetho yemvelo.
Kafushane, izihlungi ezisebenzayo ezifakwe ekhabetheni zimelela intuthuko ebalulekile emkhakheni wokuphathwa kwekhwalithi yamandla.Ikhono labo lokunciphisa ama-harmonics, ukuthuthukisa isici samandla kanye nokuqinisekisa ukunikezwa kukagesi ozinzile futhi ohlanzekile kubenza babaluleke kakhulu ezinhlotsheni eziningi zezinhlelo zokusebenza zezimboni, ezentengiselwano nezisetshenziswayo.Njengoba amabhizinisi nezinsiza ziqhubeka nokubeka phambili ukwethembeka nokusebenza kahle kwezinhlelo zabo zokusabalalisa, ukwamukelwa kwezihlungi ezisebenzayo ezifakwe kwikhabhinethi kuzoba yisu elibalulekile elibalulekile ukuze kuzuzwe futhi kugcinwe izinga eliphezulu lamandla.
