Isihluzi se-harmonic esisebenzayoluhlobo lwesixhobo sombane esisetyenziselwa ukuphelisa ukuphazamiseka kwe-harmonic kwiinkqubo zamandla ombane.Ukugqwethwa kweHarmonic kubhekiselele kubukho bamaza amaza angafunekiyo kwinkqubo yamandla enokukhokelela kumbandela wokufudumeza okwandisiweyo kwesixhobo, ukunciphisa ukusebenza kakuhle kwenkqubo, kunye nokwenza isixhobo sokusilela emsebenzini.
Isihluzi esisebenzayo se-harmonic sisebenza ngokubona i-harmonic yangoku kwisistim kunye nokuvelisa i-counter-current yobukhulu obufanayo kwisigaba esichaseneyo.Le counter-current irhoxisa i-harmonic yangoku kwaye ithintele ekubeni iphinde ifakwe kwinkqubo yamandla.Izihluzi ezisebenzayo ze-harmonic zenzelwe ukuba zikhawuleze kwaye zichaneke ekuphenduleni kwazo ekutshintsheni imeko ye-harmonic kwinkqubo yamandla.
Umthwalo wangoku ufunyenwe yi-transformer yangoku kwaye ibalwa yi-DSP yangaphakathi ukukhupha amacandelo e-harmonic yomthwalo wangoku, kwaye emva koko ithunyelwe kwi-IGBT yangaphakathi ngesignali ye-PWM yokulawula i-inverter ukuvelisa isigaba kunye nomthwalo we-harmonic ubungakanani bangoku, kwaye i-harmonic current kwicala elichaseneyo ifakwe kwigridi yamandla ukufezekisa injongo yokucoca.
Umsebenzi womyalelo wesekethe yangoku yokufumanisa ubukhulu becala ukwahlula icandelo langoku le-harmonic kunye nesiseko esisebenzayo ngoku ukusuka kumthwalo wangoku, kwaye emva koko isiphumo se-polarity esibuyisela imbuyekezo yangoku emva komqondiso womyalelo.Umsebenzi wesiphaluka solawulo lokulandelela umkhondo kukubala i-trigger pulse yesixhobo ngasinye sokutshintsha kwisekethe ephambili ngokwembuyekezo yangoku eyenziwa yi-circuit engundoqo.I-pulse yenziwa kwisekethe ephambili emva kwesekethe yokuqhuba.Ngale ndlela, unikezelo lwamandla lwangoku luqulethe kuphela icandelo elisebenzayo lamaza asisiseko, ukuze kufezekiswe injongo yokupheliswa kwe-harmonic kunye nembuyekezo yamandla asebenzayo.
I-Xi'an Noker Electric ngumvelisi wemveliso esemgangathweni yamandla, ebonelelaisihluzo samandla asebenzayokunye nezinye izisombululo.Ukuba unengxaki yobulunga bamandla, nceda uzive ukhululekile ukuqhagamshelana nathi.
