Injin canza wutar lantarki na OTIS OVF20 yana taka muhimmiyar rawa a tsarin lif na zamani, yana tabbatar da aiki mai santsi da aminci. Babban aikinsa shine canza wutar AC da aka bayar ga lif zuwa fitarwa mai canzawa, mai canzawa-mita AC wanda ke tuƙa motar yadda ya kamata.
Tsarin yana farawa da wutar AC mai shigowa, ko dai 380V ko 220V, wanda aka fara mayar da shi zuwa wutar DC ta hanyar tsarin gyarawa a cikin inverter. Wannan wutar DC ana daidaita ta ta hanyar capacitors a cikin da'irar DC don samar da wadata mai dorewa. Sannan inverter yana amfani da tsarin daidaitawa mai faɗi na bugun jini (PWM) don canza wannan DC da aka gyara zuwa wutar AC tare da mita mai daidaitawa, yana kammala aikin inverter.
A cikin OVF20, abu na farko da ake iya gani bayan buɗe murfin gaba shine Motion Control Board II (MCBII). Kamar yadda sunansa ya nuna, wannan allon yana da alhakin sarrafa tsarin motsi na lif. Yana aiki a matsayin hanyar haɗin gwiwa ga duk siginar shigarwa da fitarwa na OVF20 kuma yana sarrafa waɗannan siginar don tabbatar da aiki daidai.
Tsarin sarrafa lif - kamar LBII, LCBII, ko wasu allunan sarrafawa - yana aika umarnin gudu zuwa MCBII. MCBII yana sarrafa waɗannan umarni tare da ƙarin siginar hawa, gami da da'irorin aminci. Sannan yana aika siginar sarrafawa zuwa Allon Mashin Wuta (PDB), wanda ke sarrafa manyan transistor a cikin inverter don yin ainihin canjin AC. Ainihin, PDB yana aiwatar da sauya wutar lantarki na inverter a ƙarƙashin jagorancin MCBII.
Don yin aiki daidai, MCBII kuma yana karɓar ra'ayi daga na'urar firikwensin gudu ta PVT. Ta hanyar kwatanta ainihin saurin lif ɗin da saurin da aka umarta, MCBII yana daidaita fitowar motar don kiyaye motsi mai santsi da aminci. Layuka biyu daga inverter suna ba da ra'ayi na yanzu ga MCBII a matsayin wani ɓangare na tsarin kariyar wutar lantarki ta ciki. Idan wutar lantarki ta wuce ƙimar da aka kimanta, inverter zai haifar da rufewa mai kariya.
A ƙarshe, OVF20 ya haɗa da tsarin resistor na birki. Ana amfani da wannan resistor don rage ƙarfin lif ɗin lafiya, yana mayar da makamashin da ya wuce kima zuwa zafi don tabbatar da tsayawa mai kyau da aminci.
Gabaɗaya, na'urar canza wutar lantarki ta OTIS OVF20 tana haɗa daidaitaccen sarrafa motsi, amsawar lokaci-lokaci, da hanyoyin aminci don samar da ingantaccen aiki ga lif na zamani.
