Isihlungi se-harmonic esisebenzayoiwuhlobo lwedivayisi ye-elekthronikhi esetshenziselwa ukuqeda ukuhlanekezelwa kwe-harmonic ezinhlelweni zamandla kagesi.Ukuhlanekezelwa kwe-Harmonic kusho ukuba khona kwegagasi elingafuneki lemvamisa ohlelweni lwamandla okungaholela ekukhishweni kokwanda kokushisisa okokusebenza, ukunciphisa ukusebenza kahle kwesistimu, ngisho nokwenza ukungasebenzi kwemishini emsebenzini.
Isihlungi se-harmonic esisebenzayo sisebenza ngokuthola amandla e-harmonic kusistimu futhi sikhiqize i-counter-current yobukhulu obufanayo isigaba esiphambene.Le counter-current ikhansela i-harmonic current futhi ivimbele ukuthi ibuyiselwe kusistimu yamandla.Izihlungi ze-harmonic ezisebenzayo zenzelwe ukuthi zisheshe futhi zinembile ekuphenduleni kwazo ekushintsheni isimo se-harmonic ohlelweni lwamandla.
Umthwalo wamanje utholwa yi-transformer yamanje futhi ubalwa yi-DSP yangaphakathi ukuze kukhishwe izingxenye ze-harmonic zomthwalo wamanje, bese ithunyelwa ku-IGBT yangaphakathi ngesignali ye-PWM ukulawula inverter ukukhiqiza isigaba ngosayizi wamanje we-harmonic womthwalo, futhi i-harmonic current ibheke kolunye uhlangothi ijovwa kugridi yamandla ukuze kufezwe injongo yokuhlunga.
Umsebenzi womyalo wesifunda sokuthola wamanje ngokuyinhloko ukuhlukanisa ingxenye yamanje ye-harmonic kanye nesisekelo samanje esisebenzayo kusukela kumthwalo wamanje, bese kuba umphumela wokuhlehla we-polarity wamanje wesinxephezelo ngemva kwesignali yomyalo.Umsebenzi wesekethe yamanje yokulawula ukulandelela ukubala i-trigger pulse yedivayisi ngayinye yokushintsha kusekethe eyinhloko ngokuya ngesilinganiso samanje sesinxephezelo esikhiqizwe isifunda esikhulu.I-pulse yenziwa kusekethe enkulu ngemuva kwesekethe yokushayela.Ngale ndlela, amandla amanje aqukethe kuphela ingxenye esebenzayo yegagasi eliyisisekelo, ukuze kuzuzwe injongo yokuqedwa kwe-harmonic kanye nesinxephezelo samandla asebenzayo.
I-Xi'an Noker Electric ingumkhiqizi womkhiqizo wekhwalithi yamandla ochwepheshe, ehlinzekayoisihlungi samandla asebenzayonezinye izixazululo.Uma unenkinga yekhwalithi yamandla, sicela ukhululeke ukuxhumana nathi.
