Ezinhlotsheni ze-inverter kanye nokwehluka

Ngokuya ngezidingo zakho ezithile kanye nezidingo, ungakhetha ezinhlotsheni ezahlukahlukene zama-inverter.Lokhu kufaka phakathi igagasi lesikwele, igagasi lesikwele elilungisiwe, kanye ne-inverter ye-sine wave ehlanzekile.Wonke aguqula amandla kagesi asuka emthonjeni we-DC abe wamanje oshintshanayo, osetshenziswa izinto zikagesi.I-inverter nayo ingashintshwa ukuze ikhiqize i-voltage oyidingayo.

Uma ungathanda ukuthenga i-inverter entsha, kufanele ubale isamba samandla asetshenziswayo ezinsizeni zakho.Isilinganiso samandla sisonke se-inverter sichaza ukuthi angakanani amandla idivayisi engawanikeza ekulayisheni.Lokhu kuvame ukuvezwa ngama-watts noma ama-kilowatt.Ungathola futhi i-inverter enesilinganiso esiphezulu samandla aphezulu, kodwa lokhu kuvame ukubiza kakhulu.

Enye yezinhlobo eziyisisekelo kakhulu zama-inverter, i-square wave inverter, iguqula umthombo we-DC ube okukhiphayo kwe-AC yamagagasi ayisikwele.Le wave ine-voltage ephansi futhi yamanje, okuyenza ilungele izinhlelo zokusebenza ezizwela kancane.Futhi kuwuhlobo olushibhile lwe-inverter.Kodwa-ke, le fomu yegagasi ingakha umsindo "ohumming" uma ixhunywe kumishini yomsindo.Ayizifanelekeli kahle izinto zikagesi ezibucayi nezinye izisetshenziswa.

Uhlobo lwesibili lwe-inverter, igagasi lesikwele elilungisiwe, liguqula umthombo we-DC ube wamanje oshintshanayo.Isebenza kakhulu kunegagasi lesikwele, kodwa ayibushelelezi kangako.Lolu hlobo lwe-inverter lungathatha amaminithi ambalwa ukukhahlela. Akuyona inketho enhle ezinsizeni ezidinga ukuqaliswa okusheshayo.Ngaphezu kwalokho, isici se-THD (ingqikithi yokuhlanekezelwa kwe-harmonic) yegagasi ingaba phezulu, okwenza kube nzima kwezinye izinhlelo zokusebenza.Igagasi lingabuye lilungiswe ukuze likhiqize igagasi le-sine elicindezelweyo noma eliguquliwe.

Ama-inverters angaklanywa ngama-topology ahlukene wesekethe yamandla, ngayinye ekhuluma ngezinkinga ezahlukahlukene.Ama-inverters angasetshenziswa futhi ukukhiqiza amagagasi e-sine aguquliwe, amagagasi ayisikwele ashayekile noma ashintshiwe, noma amagagasi e-sine ahlanzekile.Ungaphinda ukhethe i-inverter ene-voltage, enezici ze-buck-converter.Lezi zinhlobo zama-inverter ngokuvamile zincane, zilula, futhi zibiza kancane kunama-inverter asekelwe ku-transformer.

Ama-inverters nawo anenketho yokusebenzisa isekethe ye-thyristor.Isifunda se-thyristor silawulwa yi-capacitor yokushintsha, elawula ukugeleza kwamanje.Lokhu kuvumela ama-thyristors ukuthi anikeze amandla amakhulu okubamba amandla.Kukhona namasekhethi okushintsha aphoqelelwe angangezwa kuma-SCR.

Uhlobo lwesithathu lwe-inverter, i-inverter ye-multilevel, ingakhiqiza i-voltage ye-AC ephezulu kumadivayisi anesilinganiso esiphansi.Lolu hlobo lwe-inverter lusebenzisa izinhlobonhlobo zama-topology wesekethe ukuze kuthuthukiswe ukulahleka kokushintsha.Ingenziwa njengochungechunge noma isifunda esihambisanayo.Ingasetshenziswa futhi ekunikezeni amandla okubekwe eceleni ukuze kuqedwe ukushintshwa kwesikhashana.

Ngaphandle kwezinhlobo zama-inverter okukhulunywe ngazo ngenhla, ungasebenzisa futhi i-inverter eguquguqukayo yokulawula imvamisa ukwenza ngcono i-waveform nokukuvumela ukuthi ulungise i-voltage ephumayo.Lolu hlobo lwesiguquli lungaphinda lusebenzise amasu ahlukene okulawula ukuze kuthuthukiswe ukusebenza kahle kwe-inverter.de.
