Masu ba da kayan tallafi na mitar mitar suna tunatar da ku cewa a cikin tsarin sarrafa mitar na al'ada wanda ya ƙunshi masu jujjuya mitoci na gabaɗaya, injina asynchronous, da lodin inji:
Lokacin da aka sauke yuwuwar nauyin da injin lantarki ke watsawa, injin ɗin na iya kasancewa cikin yanayin birki mai sabuntawa; Ko kuma lokacin da motar ta tsaya ko ta ragu daga babban gudu zuwa ƙananan gudu, mitar na iya raguwa ba zato ba tsammani, amma saboda inertia na injin, yana iya kasancewa cikin yanayin samar da wutar lantarki.
Ƙarfin injin da aka adana a cikin tsarin watsawa yana jujjuya zuwa makamashin lantarki ta injin lantarki kuma a mayar da shi zuwa da'irar DC na mai sauya mitar ta hanyar diodes masu motsi guda shida na inverter. A wannan lokacin, inverter yana cikin yanayin gyarawa. Idan ba a ɗauki matakan cinye makamashi a cikin inverter ba, wannan makamashin zai haifar da ƙarfin lantarki na capacitor na ajiyar makamashi a cikin tsaka-tsakin da'ira ya tashi.
Idan birki ya yi sauri sosai ko kuma nauyin injin yana da ƙarfi, wannan makamashi na iya haifar da lahani ga mai sauya mitar, don haka ya kamata mu yi la'akari da zubar da wannan makamashin.
A cikin masu sauya mitar gabaɗaya, akwai hanyoyin da aka fi amfani da su don sarrafa sabunta makamashi:
(1) Rushewar da aka saita ta wucin gadi "braking resistor" a layi daya tare da capacitor a cikin da'irar DC ana kiransa yanayin birki mai ƙarfi.
(2) Shigar da naúrar ra'ayi don mayar da martani ga grid wutar lantarki ana kiranta yanayin birki na martani (wanda kuma aka sani da yanayin sake fasalin birki).
Akwai wata hanyar birki, wato DC birki, wanda za'a iya amfani dashi a yanayin da ake buƙatar ingantaccen filin ajiye motoci ko lokacin da motar birki ke juyawa ba bisa ƙa'ida ba saboda abubuwan waje kafin farawa.
