Umhlinzeki weyunithi yamabhuleki: Ekusebenzeni kwemishini yezimboni, ukubhuleka ngokushesha kuyadingeka. Amandla emishini (amandla e-kinetic namandla angaba khona) ku-motor shaft aguqulwa abe amandla kagesi avuselelayo ngenjini. Ama-capacitor aphakathi nendawo yesiguquli sefrikhwensi awakwazi ukusigcina phakathi kwebanga le-voltage elishiwo, noma ukumelana nokubhuleka kwangaphakathi akukwazi ukusetshenziswa ngesikhathi, okubuyisela kutheminali yebhasi ye-DC yesiguquli sefrikhwensi, okuholela ekukhuphukeni ngokweqile engxenyeni ye-DC yesiguquli sefrikhwensi.
Ngalesi sikhathi, iyunithi ethile yokubhuleka ye-frequency yangaphandle (noma eyakhelwe ngaphakathi) kanye ne-frequency converter ethize ye-braking resistor iyadingeka ukuze kusheshiswe ukusetshenziswa kwamandla avuselelwayo, kuqinisekiswe ukufezeka kwezidingo zamabhuleki asheshayo emishini esebenzayo, nokuvikela isiguquli sefrikhwensi ekuphazamisekeni kwala mandla okuvuselela kanye nezimo zokugcwala ngokweqile.
Umgomo weyunithi yokubhuleka: Iyunithi yokubhuleka yakhiwe i-transistor yamandla aphezulu i-GTR kanye nesekethe yayo yokushayela. Umsebenzi wayo ukuhlinzeka ngendlela yokuthi i-IB yamanje yokukhipha igeleze. Lapho umshini osebenzayo udinga ukubhuleka ngokushesha, futhi phakathi nesikhathi esidingekayo, amandla okuvuselela kabusha esiguquli semvamisa awakwazi ukugcinwa ku-capacitor emaphakathi phakathi kwebanga le-voltage elishiwo noma isixhasi sangaphakathi sokubhuleka asikwazi ukusisebenzisa ngesikhathi, okubangela ukugcwala ngokweqile engxenyeni ye-DC, ingxenye yangaphandle yokubhuleka idinga ukungezwa ukusheshisa ukusetshenziswa kwamandla okuvuselela.
Umgomo wokumelana namabhuleki: Ngesikhathi senqubo yokunciphisa imvamisa yokusebenza, injini kagesi izoba sesimweni sokubhuleka kabusha, futhi amandla e-kinetic wesistimu yokushayela azobuyiselwa kusekethe ye-DC, okubangele ukuthi i-DC voltage UD iqhubeke ikhuphuka futhi ifinyelele ngisho nezinga eliyingozi. Ngakho-ke, kuyadingeka ukusebenzisa amandla avuselelwe kusekethe ye-DC ukuze kugcinwe i-UD ngaphakathi kwebanga elivumelekile. I-resistor yokubhuleka isetshenziselwa ukudla la mandla.
Iyunithi ye-Braking+resistor: Ngesikhathi senqubo yokunciphisa imvamisa yokusebenza, injini izoba sesimweni sokubhuleka kabusha, futhi amandla e-kinetic ohlelo lokushayela azobuyiselwa kusekethe ye-DC, okubangele ukuthi i-DC voltage UD iqhubeke ikhuphuka futhi ize ifinyelele ezingeni eliyingozi. Ngakho-ke, kuyadingeka ukusebenzisa amandla avuselelwe kusekethe ye-DC ukuze kugcinwe i-UD ngaphakathi kwebanga elivumelekile. I-resistor yokubhuleka isetshenziselwa ukudla la mandla. Iyunithi yokubhuleka yakhiwe i-transistor enamandla amakhulu i-GTR kanye nomjikelezo wayo wokushayela. Umsebenzi wayo ukuhlinzeka ngendlela yokuthi i-IB yamanje yokukhipha igeleze ku-resistor braking.
