Abahlinzeki bempahla yokonga ikheshi bakukhumbuza ukuthi ukusetshenziswa okungokoqobo kwempendulo yempendulo yamandla ubuchwepheshe bokonga amandla endaweni yokonga amandla kuhilela ikakhulukazi ukukhiqiza nokusebenzisa amadivaysi empendulo yamandla asekelwe kulobu buchwepheshe bempendulo. Idivayisi yempendulo yamandla yamukela iyunithi yokucubungula emaphakathi ye-DSP, enejubane eliphezulu, ukunemba okuphezulu, ukuzinza okuhle, ama-harmonics aphansi, nekhono eliqinile lokulwa nokuphazamiseka; Ukwamukela ubuchwepheshe bokuguquguquka kobubanzi be-PWM, isigaba sokuphumayo sinembile, sicindezela ngempumelelo ama-harmonics we-oda eliphezulu; Ubuchwepheshe bokuzibonela kanye nokulandelela i-voltage okuzenzakalelayo kwe-bidirectional kuqinisekisa i-voltage enembile yokuphumayo, kuvimbela ukugeleza kwamanje, nokuqinisekisa ukuthi ilifti alithinteki nganoma iyiphi indlela; Ukuhlanekezelwa kwamandla kagesi<5%, ngokuhambisana nezidingo ze-IEC6100-3-2 kanye ne-GB/T14549 yama-harmonics egridi yamandla; Ngokusebenzisa ubuchwepheshe bokuzihlonza kwegridi kanye nokusebenzisa ama-reactor nezihlungi, ingaxhunywa ngokuqondile kugridi engu-220V/380V ukuze isetshenziswe, okuholela ekongeni kwamandla okubaluleke kakhulu ezimeni zokubhuleka njalo.
Uma ilifti yefrikhwensi eguquguqukayo ingasebenzisa idivayisi yempendulo yamandla ekheshi, ingaguqula kahle amandla e-DC agcinwe ku-capacitor ibe amandla e-AC futhi iwabuyisele kugridi, ngenani lokonga amandla elingu-25% -50%. Ngaphezu kwalokho, ngenxa yokungabikho kwezinto zokushisa eziphikisanayo, izinga lokushisa elizungezile ekamelweni lomshini liye lancishiswa, futhi izinga lokushisa lokusebenza lesistimu yokulawula i-elevator liye lathuthukiswa, ukuvimbela uhlelo lokulawula ukuthi lungaphahlazeka futhi lwandise impilo yesevisi ye-elevator. Igumbi lekhompiyutha alisakwazi ukusebenzisa isiphephetha-moya nezinye izinto zokupholisa, ezingasindisa ukusetshenziswa kwamandla kwegumbi lekhompiyutha okokupholisa umoya kanye nemishini yokupholisa, yonge amandla nokuvikelwa kwemvelo, futhi yenze ikheshi liwonge kakhudlwana amandla.
Idivayisi yempendulo ingaziba umthombo wokushisa wokumelana ngoba ayisebenzisi izinto ezivimbela ukusetshenziswa okuphezulu. Ngaphezu kwalokho, ngenxa yokuthi akukho resistor, izinga lokushisa ekamelweni lomshini we-elevator ngeke libe phezulu kakhulu, okunciphisa kakhulu amathuba okuhluleka kwe-elevator, kwandisa impilo yesevisi ye-elevator, futhi kunciphisa ngokuphumelelayo ukusetshenziswa kwamandla kwemishini yokupholisa ekamelweni lomshini. Ngale ndlela, ukusebenza kahle okonga amandla kukhuphuka kakhulu. Yiqiniso, umphumela wokonga amandla uzobonakala kakhulu ngaphansi kwamandla aphezulu, izakhiwo eziphakeme, nokusetshenziswa njalo.
Idivayisi yempendulo yamandla inesici esivelele kakhulu, okuwumsebenzi wempendulo yokulawula okuguquguqukayo kagesi. Ekusetshenzisweni okungokoqobo, lo msebenzi ubaluleke kakhulu ngoba lapho i-voltage yegridi ishintshashintsha kakhulu, ilifti lisazosebenza njengokujwayelekile. Ngaphezu kwalokho, kuphela lapho amandla omshini we-elevator eguqulwa abe amandla kagesi futhi athunyelwe ku-DC circuit capacitor, idivayisi entsha yempendulo yamandla kagesi ingabuyisela ngesikhathi esifanele amandla agciniwe ku-capacitor kugridi, ixazulule ngokuphumelelayo ukushiyeka kwempendulo yamandla okuqala. Inganciphisa ukuphazamiseka kwe-harmonic kwesiguquli semvamisa ukushayela ilifthi kugridi yamandla futhi ihlanze indawo yegridi yamandla. Idivayisi yempendulo yamandla kagesi ingcono kakhulu kuneyunithi yeyunithi yeyunithi ye-resissive resistive braking esebenzisa amandla, ithuthukisa indawo yegumbi lomshini, inciphisa imiphumela emibi yokushisa okuphezulu ezingxenyeni zesistimu yokulawula, nokwelula impilo yesevisi yemishini ye-elevator.
