Domin gane saurin aiki na injin, ana amfani da fasahar inverter sosai a cikin injin da ke hana fashewa.A matsayin na'ura, mai jujjuyawar na iya canza wutar lantarki ta mitar wutar lantarki (50Hz ko 60Hz) zuwa nau'in wutar lantarki na AC iri-iri, ta yadda za a cimma matsayar saurin aiki na injin.Na'urar ta haɗa da da'irar sarrafawa don sarrafa babban kewayawa;Da'irar gyara don jujjuya canjin halin yanzu zuwa halin yanzu kai tsaye;Ana amfani da tsaka-tsakin tsaka-tsakin DC don santsi da tace abubuwan da aka fitar na da'irar gyarawa;Inverter circuit, ana amfani da shi don canza halin yanzu kai tsaye zuwa madaidaicin halin yanzu.A wasu na'urori masu sauya mitar da ke buƙatar aiwatar da ayyuka da yawa, kuma ya zama dole a samar da na'urar CPU don lissafin juzu'i da kuma da'irar da ta dace.Ta hanyar canza mitar samar da wutar lantarki na iskar stator na motar, ƙa'idar saurin mitar mai canzawa na iya gane manufar daidaita saurin.
Inverter Dangane da hanyoyin rarrabuwa daban-daban, ana iya raba shi zuwa nau'in inverter irin ƙarfin lantarki da nau'in inverter na yanzu, PAM control inverter, PWM iko inverter da babban mai ɗaukar hoto PWM iko inverter, V / f iko inverter, zamewa mitar iko inverter da vector iko inverter, Janar. inverter, babban aiki na musamman inverter, babban mitar inverter, juzu'i mai jujjuyawa da inverter lokaci uku, da sauransu.
A cikin mai sauya mitar, VVVF tana nufin canza wutar lantarki da mitar, yayin da CVCF ke nufin wutar lantarki akai-akai da akai-akai.A cikin wutar lantarki ta AC da ake amfani da ita a cikin ƙasashe na duniya, a cikin gidaje ko masana'antu, ƙarfin lantarki da mita yawanci 400V/50Hz ko 200V/60Hz(50Hz).Na'urar da ke canza irin wannan wutar lantarki zuwa wutar lantarki ko mitar wutar lantarki AC ana kiranta "frequency Converter".Domin samar da madaidaicin ƙarfin lantarki da mitoci, na'urar tana buƙatar farko ta canza canjin halin yanzu zuwa kai tsaye (DC).
Ana amfani da mai sauya mitar don sarrafa motar kuma yana iya canza duka ƙarfin lantarki da mita.Dangane da yanayin saurin motsin AC, gudun n yana daidai da mitar f, kuma ana iya daidaita saurin motar muddin aka canza mitar f.Sabili da haka, mai sauya mitar yana gane ƙa'idodin saurin gudu ta hanyar canza mitar wutar lantarki ta motar, wanda shine babban inganci da ƙa'idar saurin aiki yana nufin.
A cikin haɓaka masu sauya mitoci, hanyoyin sarrafawa iri-iri sun samo asali, gami da:
Sinusoidal pulse width modulation (SPWM) yanayin sarrafawa, inda 1U/f=C;
Yanayin sarrafa wutar lantarki na sararin samaniya (SVPWM);
Yanayin sarrafa Vector (VC);
Yanayin sarrafa karfin kai tsaye (DTC);
Matrix intersection - yanayin kula da tsaka-tsaki, da dai sauransu.
A sama, an bayyana sabon aikace-aikacen inverter a cikin motar da ba ta iya fashewa.Ta hanyar fasahar inverter, za'a iya daidaita saurin motar a hankali, yana kawo babban inganci da babban ƙarfin ikon aiki a fagen masana'antu.
