Kwimeko yetekhnoloji yanamhlanje eguquka ngokukhawuleza, imfuno yombane ayizange ibe nkulu.Njengoko ukusetyenziswa kwezixhobo ze-elektroniki kuqhubeka ukwanda kunye nemisebenzi yemizi-mveliso isanda, umgangatho wamandla uye waba yinkxalabo ebalulekileyo kumashishini kunye nezinto eziluncedo.KulaphoIzihluzi ezisebenzayo ezifakwe kwikhabhathi ziyezaekudlalweni, ukubonelela ngesisombululo esithembekileyo, esisebenzayo sokunciphisa i-harmonics, ukuphucula umbane kunye nokuqinisekisa unikezelo lwamandla oluzinzileyo nolucocekileyo.
Izihluzi ezisebenzayo ezifakwe kwiKhabhinethi zizinto ezibalulekileyo kwiinkqubo zokusasazwa kwamandla kwaye ziyilelwe ukubonelela ngokusebenza okuphezulu ekupheliseni ukugqwetheka kwe-harmonic kunye nokuphucula umgangatho wamandla.Esi sixhobo esitsha sixhunyiwe kwigridi yamandla ngokuhambelana kwaye sibona i-voltage kunye ne-current yento yembuyekezo ngexesha langempela.Ngokusebenzisa itekhnoloji yekhompyuter kunye nolawulo oluphezulu, ivelisa ngokufanelekileyo i-reverse-phase, i-amplitude currents ezilinganayo ukuphelisa i-harmonic currents ezikhoyo kwigridi yamandla.Oku kuphelisa ii-harmonics ezingafunekiyo, ukuphucula kakhulu umgangatho wamandla.
Intliziyo yesihluzo esisebenzayo esifakwe kwikhabhinethi ngumyalelo weyunithi yokusebenza yangoku, edlala indima ebalulekileyo ekuququzeleleni imisebenzi yayo eguquguqukayo.Itekhnoloji yokuguqula i-wideband ye-pulse modulation signal isetyenziselwa ukuqhuba imodyuli ephantsi ye-IGBT kwaye ifake i-current eveliswayo kwigridi yamandla.Ngoko ke, i-harmonics ingathathi hlangothi ngokufanelekileyo, iqinisekisa ukuba amandla anikezelwe kumthwalo odibeneyo awuphazamiseki kwaye aguquguquke.Oku kuchaneka kunye nokuphendula kwenza izihluzi ezisebenzayo ezifakwe kwikhabhinethi zibe sisixhobo esiyimfuneko sokugcina umgangatho wamandla uphezulu kwiinkqubo ezahlukeneyo.
Njengoko abantu behlawula ingqalelo ngakumbi nangakumbi ekukhuselweni kwendalo kunye nezenzo ezizinzileyo, indima yohluzo lwekhabhinethi esebenzayo ekunciphiseni ukusetyenziswa kwamandla kunye nokuphucula ukusebenza kakuhle akunakuncitshiswa.Ngokususa i-harmonics kunye namandla asebenzayo, ezi zihluzo aziphuculi kuphela umgangatho wamandla kodwa zikwanceda ukunciphisa ilahleko yamandla kunye neendleko zokusebenza ngokubanzi.Oku kubenza babe lutyalo-mali olunomtsalane kumashishini ajonge ukuphucula ukusebenza kwenkqubo yokusasazwa ngelixa bethobela imigangatho nemimiselo yokusingqongileyo.
Isishwankathelo, izihluzi ezisebenzayo ezifakwe kwikhabhinethi zibonisa ukuqhubela phambili okubalulekileyo kwinkalo yolawulo lomgangatho wamandla.Ukukwazi kwabo ukunciphisa i-harmonics, ukuphucula umbane kunye nokuqinisekisa unikezelo lwamandla oluzinzileyo nolucocekileyo lubenza babe yimfuneko kuluhlu olubanzi lwezicelo zemizi-mveliso, urhwebo kunye nezinto eziluncedo.Njengoko amashishini kunye nezinto eziluncedo ziqhubeka nokubeka phambili ukuthembeka kunye nokusebenza kakuhle kweenkqubo zabo zokusasaza, ukwamkelwa kwezihluzo ezisebenzayo ezifakwe kwikhabhinethi kuya kuba yinto ephambili yeqhinga lokufezekisa nokugcina umgangatho wamandla uphezulu.
