Mai samar da na'ura mai jujjuya birki na mitar yana tunatar da ku cewa mai sauya mitar na'urar sarrafa wutar lantarki ce da ke amfani da fasahar sauya mitar da fasahar microelectronics don sarrafa injinan AC ta hanyar canza mitar wutar lantarki da injin ke aiki. Mai sauya mitar ya ƙunshi gyara (AC zuwa DC), tacewa, jujjuyawa (DC zuwa AC), naúrar birki, naúrar tuƙi, sashin ganowa, naúrar microprocessor, da sauransu.
1. Ajiye makamashi ta hanyar daidaita saurin
Don tabbatar da amincin kayan aikin samarwa, masana'antun masana'antu suna barin wani tazara tsakanin ƙarfin tuƙi da ƙirar ƙira. Saboda haka, yawancin motoci ba za su yi aiki da cikakken kaya ba, wanda ke haifar da wuce gona da iri da ƙara yawan ƙarfin aiki, wanda ke haifar da ɓarnawar makamashin lantarki. Don wannan yanayin, aikin sarrafa saurin mai sauya mitar na iya rage saurin aiki na motar, ta yadda zai rage yawan amfani da makamashin lantarki yayin da yake riƙe da wutar lantarki akai-akai.
Idan gudun motar ya ragu daga N1 zuwa N2, ikon shaft ɗinsa P zai zama:
P2/P1 = (N2/N1)3
Ana iya ganin cewa rage saurin motar zai iya cimma tasirin ceton makamashi mai siffar cubic.
2. Energy ceto ta hanyar tsauri daidaita yadda ya dace
Ma'aunin da aka daidaita da kansa da aikin fitarwa mai sarrafa mitar mai canzawa yana ci gaba da lura da canje-canjen kaya kuma da sauri yana yin gyare-gyare don daidaitawa ga canje-canjen lodi, ta haka yana riƙe babban ingancin fitowar motar a kowane lokaci.
3. Ajiye makamashi ta hanyar aikin V / F
A ƙarƙashin yanayin tabbatar da ƙarfin fitarwa na motar, mai sauya mitar na iya daidaita madaidaicin V / F ta atomatik, rage ƙarfin fitarwa na motar da rage yawan shigar da halin yanzu, don haka cimma burin kiyaye makamashi.
4. Ajiye makamashi ta hanyar aikin farawa mai laushi
Kamar yadda aka sani, lokacin da motar ta fara da cikakken ƙarfin lantarki, halin yanzu da ake sha daga grid ɗin wutar lantarki bisa ga buƙatun farawa na injin yana kusan sau 7 ƙimar halin yanzu na motar. Duk da haka, idan farkon halin yanzu yana da girma, ba wai kawai yana lalata wutar lantarki ba, amma kuma yana haifar da gagarumin canje-canje a cikin wutar lantarki. Ci gaba da jujjuyawar grid ɗin wutar lantarki kuma zai ƙara hasarar layi da asarar transfoma. Ta hanyar aikin farawa mai laushi na mai sauya mitar, farkon halin yanzu na motar zai iya karuwa a hankali daga 0 zuwa ƙimar halin yanzu na motar, yadda ya kamata ya rage tasirin farawa a kan grid na wutar lantarki. Wannan ba wai kawai yana rage ɓatar da babban ƙarfin lantarki na yanzu ba, amma kuma yana rage tasirin farawa akan kayan aiki, rage asarar rayuwar kayan aiki.
5. Ajiye makamashi ta hanyar inganta wutar lantarki
Yawancin injunan asynchronous masu hawa uku suna cikin nau'ikan inductive, kuma saboda yawan adadin kuzarin da injin ke ɗauka yayin aiki, yanayin wutar lantarki ya yi ƙasa kaɗan. Bayan ɗaukar mai sauya mitar, halayensa sun zama AC-DC-AC. Ta hanyar gyaran gyare-gyare da tacewa na mai sauya mitar, halayen impedance na grid na wutar lantarki sun zama masu tsayayya, wanda ke inganta yanayin wutar lantarki kuma yana rage asarar wutar lantarki.
Gabaɗaya, masu juyawa na mitar suna da wasu tasirin ceton kuzari a yanayi da yawa, har ma suna da tasiri sosai a wasu yanayi. Don haka, a matsayin ingantacciyar ƙirƙira ta fasaha, masu sauya mitar suna da mahimmancin haɓaka haɓakawa da ƙarfi.
