Izinhlobo ze-inverter kanye nomehluko

Kuye ngezidingo zakho ezithile kanye nezidingo zakho, ungakhetha ezinhlobonhlobo zezinhlobo ezahlukene zama-inverter. Lokhu kufaka phakathi i-square wave, i-modified square wave, kanye ne-pure sine wave inverter. Konke kuguqula amandla kagesi avela kumthombo we-DC abe yi-alternating current, esetshenziswa yizinto zikagesi. I-inverter ingalungiswa futhi ukuze ikhiqize i-voltage oyidingayo.

Uma unesifiso sokuthenga i-inverter entsha, kufanele ubale ukusetshenziswa kwamandla okuphelele kwezinto zakho zikagesi. Isilinganiso samandla esiphelele se-inverter sichaza ukuthi idivayisi inganikeza amandla angakanani emthwalweni. Lokhu kuvame ukuvezwa ngama-watts noma ama-kilowatts. Ungathola futhi i-inverter enesilinganiso esiphezulu samandla aphezulu, kodwa lokhu kuvame ukubiza kakhulu.

Enye yezinhlobo eziyisisekelo zama-inverter, i-square wave inverter, iguqula umthombo we-DC ube yi-AC output yamaza ayisikwele. Leli wave liphansi kakhulu ku-voltage kanye nogesi, okwenza libe lihle kakhulu ekusetshenzisweni okuphansi kokuzwela. Futhi liwuhlobo lwe-inverter olushibhile kakhulu. Kodwa-ke, leli waveform lingadala umsindo "wokuhumzela" uma lixhunywe kumishini yomsindo. Alifaneleki kahle kuma-electronics azwelayo kanye neminye imishini.

Uhlobo lwesibili lwe-inverter, i-wave yesikwele eguquliwe, iguqula umthombo we-DC ube yi-alternating current. Isebenza kahle kakhulu kune-wave yesikwele, kodwa ayisheleli kangako. Lolu hlobo lwe-inverter lungathatha imizuzu eminingana ukuqala. Akuyona inketho enhle yemishini edinga ukuqaliswa okusheshayo. Ngaphezu kwalokho, i-THD factor (ukuhlanekezelwa okuphelele kwe-harmonic) yegagasi ingaba phezulu, okwenza kube nzima kwezinye izinhlelo zokusebenza. Igagasi lingaguqulwa futhi ukuze likhiqize i-pulsed noma i-modified sine wave.

Ama-inverter angaklanywa ngezinhlobo ezahlukene ze-topology zamandla, ngayinye ebhekana nezinkinga ezahlukene. Ama-inverter angasetshenziswa futhi ukukhiqiza amagagasi e-sine aguquliwe, amagagasi esikwele ashukunyiswayo noma aguquliwe, noma amagagasi e-sine amsulwa. Ungakhetha futhi i-inverter ephekwe ngamandla kagesi, enezici ze-buck-converter. Lezi zinhlobo zama-inverter ngokuvamile zincane, zilula, futhi zishibhile kune-inverter esekelwe ku-transformer.

Ama-inverter nawo anenketho yokusebenzisa isekethe ye-thyristor. Isekethe ye-thyristor ilawulwa yi-commutation capacitor, elawula ukugeleza kwamandla kagesi. Lokhu kuvumela ama-thyristors ukuthi anikeze amandla amakhulu okuphatha amandla. Kukhona namasekethe okushintsha amandla aphoqelelwe angangezwa kuma-SCR.

Uhlobo lwesithathu lwe-inverter, i-inverter enamazinga amaningi, ingakhiqiza i-voltage ephezulu ye-AC kusuka kumadivayisi anesilinganiso esiphansi. Lolu hlobo lwe-inverter lusebenzisa izinhlobo ezahlukene ze-topology zesekethe ukuze luthuthukise ukulahlekelwa kokushintsha. Lungenziwa njengesekethe yochungechunge noma ehambisanayo. Lungasetshenziswa futhi ekuhlinzekweni kwamandla okulinda ukuze kuqedwe i-transient switchover.

Ngaphandle kwezinhlobo zama-inverter okukhulunywe ngawo ngenhla, ungasebenzisa futhi i-inverter yokulawula i-variable frequency motor ukuthuthukisa i-waveform nokukuvumela ukuthi ulungise i-voltage yokuphuma. Lolu hlobo lwe-inverter lungasebenzisa futhi amasu ahlukahlukene okulawula ukuze kuthuthukiswe ukusebenza kahle kwe-inverter.de.
