Abahlinzeki bemishini esekela i-frequency converter bayakukhumbuza: iyunithi yempendulo yokulungisa iyingxenye ebalulekile yesiguquli semvamisa, indima eyinhloko ukubuyisela amandla avuselelekayo akhiqizwe injini kugridi yamandla, ukuze kuzuzwe ukusetshenziswa kahle kwamandla.
Umgomo weyunithi yempendulo ye-inverter rectifier ukuthi lapho injini yehlisa ijubane noma ibhuleki, kukhiqizwa amandla avuselelekayo, okuthi uma engelashwa abangele ukuthi injini ishise noma ilimale. Iyunithi yempendulo yolungisa kabusha igwema ukumoshwa kwamandla kanye nokulimala kwezisetshenziswa ngokuguqula la mandla avuselelekayo abe yi-DC futhi iwabuyisele kugridi.
Ezinhlelweni ezingokoqobo, iyunithi yempendulo yokulungisa isetshenziswa kakhulu kumasistimu ezimoto ahlukahlukene adinga ukuqaliswa njalo, ukubhuleka nokulungiswa kwesivinini, njengamakheshi, amafeni, amaphampu amanzi, njll. Isibonelo, ezinhlelweni zamakheshi, lapho ilifti iphakama noma iwa, injini idinga ukulungiswa njalo kwejubane ukuze igcine ukusebenza kahle.
Idizayini nokwenza kahle kweyunithi yempendulo yokulungiswa kubalulekile ekuthuthukiseni ukusebenza nokuzinza kwe-inverter. Ngokuklama kwesifunda esiphusile kanye namasu okulawula, impendulo yamandla esebenza kahle, ukulahleka kwemishini ephansi kanye nempilo ende yesevisi ingafinyelelwa. Ngesikhathi esifanayo, iyunithi yempendulo yokulungisa nayo idinga ukucabangela ukuhambisana nokuphepha kwegridi ukuze kuqinisekiswe ukuthi impendulo yamanje ayibangeli ukuphazamiseka noma ilimaze igridi.
Ngamafuphi, iyunithi yempendulo yokulungisa iyingxenye ebalulekile yesiguquli sefrikhwensi. Ingaphakela amandla avuselelekayo akhiqizwa injini ibuyele kugridi, ithuthukise ukusebenza kahle kokusetshenziswa kwamandla, futhi ivikele okokusebenza emonakalweni. Ngokuklama okunengqondo nokwenza kahle, iyunithi yempendulo yokulungisa inganikeza isiqinisekiso sokusebenza esizinzile, esisebenza kahle nesinokwethenjelwa kumasistimu ezimoto ahlukahlukene.
