I-LV AHF Yokunciphisa I-Harmonics Kunethiwekhi Yogesi

Ibhekene nenkinga enzima yokungcoliswa kwe-harmonic yamandla, i-AHF iyithuluzi elisebenza kahle kakhulu lokuthuthukisa ikhwalithi yamandla. I-AHF iyisisetshenziswa esisha esikhethekile sokulawula i-harmonic yamandla esakhiwe kusetshenziswa ubuchwepheshe besimanje bamandla kagesi kanye nobuchwepheshe bokucubungula amasignali edijithali okusekelwe kumadivayisi okucubungula e-DSP anesivinini esikhulu. I-AHF ilingana nejeneretha yamanje ye-harmonic, elandelela izingxenye ze-harmonic ku-harmonic current futhi ikhiqize ama-harmonic currents nge-amplitude elinganayo nesigaba esiphambene.I-AHF iqukethe izingxenye ezimbili: umjikelezo wokusebenza kwamanje kanye nesifunda sesinxephezelo sesizukulwane samanje. Umjikelezo wokusebenza kwamanje weziyalezo uhlonza i-current in circuit ngesikhathi sangempela, uguqule isignali yamanje ye-analog ibe isignali yedijithali, futhi iyithumele kuphrosesa yedijithali enesivinini esikhulu (i-DSP) ukuze kucutshungulwe isignali. Ama-harmonic kanye nama-basic currents ahlukaniswa ukuze kutholwe isifundiso samanje, esibe sesithunyelwa kumjikelezo wesizukulwane samanje sesinxephezelo ngendlela yesignali ye-pulse wide modulation (PWM) ngokusebenzisa isifunda sokulawula ukulandelwa kwamanje kanye nesekethe yedrayivu. Amamojula wamandla e-IGBT kanye ne-IPM aqhutshwa ukuze akhiqize amandla amanje esinxephezelo ane-amplitude efanayo ne-polarity ephambene ne-harmonic current, efakwa kugridi yamandla ukuze kunxeshezelwe noma kukhanselwe i-harmonic yamanje, ukuqeda ngenkuthalo ukuhambisana kwamandla, futhi kuzuzwe ukucubungula okuguquguqukayo, okusheshayo, nokuphelele kokuvumelana kwamandla.

imininingwane yomkhiqizo

I-AHF ifanele imithwalo yezinga eliphezulu yezimboni, enjengama-rectifiers, ama-frequency converters, i-UPS enkulu, ama-arc furnaces, amafrikhwensi aphakathi nendawo, amashaja ezigaba ezintathu, nezinye izimo zomthwalo wezigaba ezintathu. Ifanele imithwalo yesigaba esisodwa engaqondile ezakhiweni zezentengiselwano, njengezibani ezonga amandla, amakhompyutha, i-UPS, ama-elevator, ama-air conditioner ashintshashintshayo, njll., akhiqiza i-harmonic yesithathu futhi ashise umugqa we-N.
