Ethintwa yiRussia ne-Ukraine, ama-inverters athandwa kakhulu

Ama-inverters ahlukaniswe ikakhulukazi izigaba ezimbili ngokuya nge-waveform:

1. Isiguquli se-sine wave esihlanzekile 2. Isiguquli segagasi esilungisiwe 3. Isiguquli segagasi esiyisikwele.

Ama-inverters e-square-wave akhipha amandla ashintshashintshayo ekhwalithi empofu yezinga eliyisikwele, futhi ukuphakama kwawo okuhle nokubi akhiqizwa cishe ngasikhathi sinye, okuzolimaza umthwalo kanye ne-inverter.Ngaphezu kwalokho, umthamo womthwalo we-square wave inverter umpofu, cishe uhhafu wamandla alinganisiwe, futhi awukwazi ukuthwala umthwalo we-inductive.

Uma kuqhathaniswa ne-square wave inverter, i-voltage waveform ye-modified sine wave inverter ithuthukiswa kakhulu, futhi okuqukethwe okuphezulu kwe-harmonic nakho kuyancishiswa.Isiguquli esiguquliwe se-sine wave sikhiqizwa ngokuphakama kancane kancane kwamagagasi aphambene.Ngale ndlela, isifunda sokulawula siyinkimbinkimbi, kukhona amashubhu okushintsha amandla emigqa ephezulu, futhi umthamo nesisindo se-inverter kukhulu.Eminyakeni yamuva nje, ngokuthuthuka okusheshayo kobuchwepheshe bamandla kagesi, ukuguquguquka kobubanzi be-PWM sekusetshenziswe kabanzi ukukhiqiza ukuphuma kwegagasi lokulungisa.Njengamanje, i-inverter ye-wave ethuthukisiwe isetshenziswe kabanzi ezinhlelweni zabasebenzisi ezindaweni ezikude, ngoba lezi zinhlelo zabasebenzisi azinazo izidingo eziphakeme ngekhwalithi yokusetshenziswa kwamandla, futhi i-inverter ethuthukisiwe ifanele ukuthwala ukumelana.

I-pure sine wave inverter ikhipha amandla aphezulu e-AC, angashayela imithwalo ehlukahlukene, futhi empeleni ayinawo umonakalo emthwalweni kanyei-inverter.Yize ama-inverter e-sine wave ahlanzekile ebiza ngaphezu kwe-square wave kanye nama-inverter e-sine aguquliwe, sisancoma ukukhetha ama-inverter e-sine wave noma nini lapho kungenzeka.

Umphumela we-voltage waveform ye-inverter ehlanzekile ye-sine wavekuhle, ukuhlanekezela kuphansi kakhulu, futhi i-waveform yokuphuma kwayo ihambisana ngokuyisisekelo ne-AC waveform yegridi yamandla.Eqinisweni, i-sine wave inverter enhle kakhulu inganikeza amandla aphezulu e-AC kunegridi.I-sine wave inverter inokuphazamiseka okuphansi kwemishini yomsakazo nezokuxhumana kanye nemishini enembayo, umsindo ophansi, nokuguquguquka okuqinile komthwalo, okungahlangabezana nazo zonke izinhlelo zokusebenza zomthwalo we-AC, ukusebenza kahle okuphelele kuphezulu.Ububi bayo ukuthi isifunda kanye ne-transformer yokuguqula i-wave correction iyinkimbinkimbi, idinga ama-chips okulawula athuthukile kanye nobuchwepheshe bokulungisa, futhi kubiza kakhulu.Endabeni yezinhlelo zokusebenza ezixhunywe kwigridi yelanga, isiguquli se-sine wave kufanele futhi sisetshenziswe ukugwema ukungcoliswa kukagesi kugridi yomphakathi.
