Isihlungi se-Harmonic Esisebenzayo (AHF)—Isigaba Esisodwa
Isifinyezo Somkhiqizo:
Izihlungi ezisebenzayo ze-harmonic (AHF) ziyimpendulo ephelele ezinkingeni zekhwalithi yamandla ezibangelwa ukuphambuka kwesimo samagagasi, amandla aphansi, ukushintshashintsha kwamandla kagesi, ukushintshashintsha kwamandla kagesi kanye nokungalingani komthwalo kwezingxenye eziningi kanye nezinhlelo zokusebenza. Ziwuhlobo lwezihlungi zamandla ezisebenzayo (i-APF) ezisebenza kahle kakhulu, ezincane, eziguquguqukayo, eziguquguqukayo futhi ezingabizi kakhulu ezinikeza impendulo esheshayo nephumelelayo ezinkingeni zekhwalithi yamandla ezinhlelweni zamandla kagesi eziphansi noma eziphezulu. Zivumela isikhathi eside semishini, ukuthembeka okuphezulu kwenqubo, amandla ohlelo lwamandla oluthuthukisiwe kanye nokuzinza, kanye nokulahlekelwa kwamandla okuncishisiwe, okuhambisana nezindinganiso zekhwalithi yamandla ezifunwa kakhulu kanye namakhodi egridi.
Ama-AHF asusa ukuphambuka kwesimo samagagasi emithwalweni efana nama-harmonics, ama-harmonics aphakathi kanye nama-notching, kanye nama-voltage e-harmonic abangelwa yi-harmonic currents, ngokufaka ngesikhathi sangempela i-current ephambukile yobukhulu obufanayo kodwa ephambene nesigaba ohlelweni lwamandla kagesi. Ngaphezu kwalokho, ama-AHF angabhekana nezinye izinkinga eziningana zekhwalithi yamandla ngokuhlanganisa imisebenzi ehlukene kudivayisi eyodwa.
Isimiso Sokusebenza:
I-CT yangaphandle ithola amandla omthwalo, i-DSP njengoba i-CPU inezibalo zokulawula okunengqondo ezithuthukisiwe, ingalandelela ngokushesha amandla omyalelo, ihlukanise amandla omthwalo abe amandla asebenzayo kanye namandla asebenzayo ngokusebenzisa i-FFT ehlakaniphile, futhi ibale okuqukethwe kwe-harmonic ngokushesha nangokunembile. Bese ithumela isignali ye-PWM ebhodini lomshayeli le-IGBT langaphakathi ukuze lilawule ukuvula nokuvala i-IGBT ngemvamisa engu-20KHZ. Ekugcineni ikhiqiza amandla okubuyisela isigaba aphambene ekufakweni kwe-inverter, ngesikhathi esifanayo i-CT ithola futhi amandla okukhipha kanye nempendulo engemihle iya ku-DSP. Bese i-DSP iqhubeka nokulawula okulandelayo okunengqondo ukuze ifinyelele uhlelo olunembile noluzinzile.
