Abahlinzeki bemishini esekela i-frequency converter bakukhumbuza ukuthi ngokuthuthukiswa kwe-automation yezimboni, i-automation kagesi nayo ithathwe njengenkomba yokulinganisa ebalulekile. Ukusebenza okuphephile nokuzinzile kwesistimu yamandla nakho kuyingxenye ebalulekile yenqubo ye-automation yezimboni. Ubuchwepheshe bokulawula isivinini esishintshashintshayo bubhekisela ekulungiseni isivinini semoto ngokufanele ngokushintsha imvamisa yamandla okusebenza ngokususelwe ebudlelwaneni obuphakathi kwejubane lemoto kanye nemvamisa yokufaka yamandla okusebenza.
Njengamanje, kube nezindlela eziningi zokulawula isivinini sokuguqulwa kwemvamisa, njengokulawula i-torque eqondile, ukulawulwa kwe-vector, njalonjalo. Ukuthuthukiswa kobuchwepheshe bokulawula idijithali kanye nokusetshenziswa kabanzi kobuchwepheshe be-semiconductor kuye kwaholela ekusetshenzisweni kabanzi kokulawulwa kwe-vector hhayi kuphela ebangeni lokusebenza okuphezulu, kodwa nasezindimeni zokushayela nezikhethekile zokushayela. Ukulawula ama-Vector nakho sekusetshenziswe kabanzi ezintweni zikagesi zasendlini njengama-air conditioner ashintshashintshayo kanye neziqandisi ezimpilweni zabantu zansuku zonke. Ngaphezu kwalokho, abashayeli be-AC baye basetshenziswa nakweminye imikhakha, njengemishini yezimboni, izimoto zikagesi, njalonjalo.
Ukusetshenziswa okunengqondo kobuchwepheshe bokulawula isivinini sokuguqula imvamisa:
Esokuqala umsebenzi wesimiso sesinxephezelo samandla asebenzayo: inhloso yokufaka imishini yesinxephezelo samandla asebenzayo ukuthuthukisa ukusebenza kahle kokunikezwa kwamandla kanye nemvelo yokuphakelwa kukagesi. Isebenzisa ngokugcwele isimiso sokushintshisana kwamandla phakathi kwezinhlobo ezimbili zemithwalo ukuze kunxeshezelwe ukulahlekelwa phakathi kweziguquli zamandla kanye nemigqa yokudlulisela. Ohlelweni lokuphakelwa kwamandla, izisetshenziswa zokunxephezela amandla asebenzayo ziyingxenye ebalulekile; Kuphela ngokukhetha izisetshenziswa zesinxephezelo ngokunengqondo nokuzisebenzisa kusistimu yamandla lapho isici samandla segridi yamandla singathuthukiswa ngempumelelo, ukulahlekelwa kwenethiwekhi kuncishiswe ngokwezinga eliphezulu, futhi ikhwalithi yegridi yamandla ingathuthukiswa ngempumelelo.
Uma ukhetha amadivaysi esinxephezelo samandla asebenzayo, ama-capacitor nama-reactors aqoqwe futhi ashintshwayo ngokuvamile ayasetshenziswa. Kwezinye izimo ezikhethekile, amakhamera ashintsha isigaba kanye namadivayisi esinxephezelo samandla asebenzayo aqinile nakho kuyisinqumo esihle; Ukuze kuhlangatshezwane nezidingo zebhalansi yamandla asebenzayo nokukhuthaza ukufezeka kwamazinga ekhwalithi kagesi, kuyadingeka ukusebenzisa imishini elawula amandla kagesi. Ukuze kusetshenziswe izimiso zokuhlukaniswa okulandelanayo nokulinganisa endaweni esinxephezelweni samandla asebenzayo kugridi yamandla, kuyadingeka futhi ukucabangela ngokugcwele amandla okulawula amandla asebenzayo eziteshi ezingaphansi, futhi kukhuthazwe ngamandla ukuthuthukiswa kwamandla kagesi kanye nesici samandla. Ubuchwepheshe obuthuthukile obufana nesofthiwe yesistimu yokulawula amandla asebenzayo egridi yamandla kufanele isetshenziswe ngokukhuthele ukuze kuthuthukiswe ikhwalithi yegridi yamandla nokuqinisekisa ukusebenza kwayo okuphephile nokuthembekile.
Okwesibili yizinga lomthwalo we-frequency converters: uma kuqhathaniswa nesikhathi sokushisa sama-transformers nama-motor, isikhathi sokushisa samadivayisi we-semiconductor ngokuvamile sincane, ngokuvamile sibalwa ngamaminithi. Uma kunenkinga yokulayisha ngokweqile noma yokushisa ngokweqile, kuzodala izinkinga ezinkulu. Ngakho-ke, kuyadingeka ukulawula ngokuqinile izimo zomthwalo. Kuyadingeka ukuhlukanisa izinhlobo zokusebenza ze-inverter. Okukhiphayo okukalwe ileveli yokuqala kuwumphumela wamanje ogcwele, futhi izimo zokugcwala ngokweqile ngeke zenzeke; Izinga lesibili lingakhipha ngokuqhubekayo umthwalo oyisisekelo wamanje, futhi ukusebenza kokugcwala ngokweqile kwesikhathi esifushane kungafinyelela ku-50%; Ukulayisha ngokweqile ukusuka kuleveli yesithathu kuya kwelesithupha kudinga isikhathi eside. Njengamanje, emakethe, ukuthengiswa ngokuvamile kwenziwa kuphela ezingeni lesibili nelokuqala. Ngaphezu kwalokho, kuyadingeka ukuhlanganisa izidingo zokusebenza komthwalo wemishini yokukhiqiza kanye nebanga lejubane ukuze wenze ukukhetha okunengqondo kweziguquli zemvamisa.
