Tare da saurin haɓaka fasahar lantarki ta zamani da fasahar sarrafa kwamfuta, an haɓaka juyin fasaha na tuƙi na lantarki.Ikon saurin AC maimakon sarrafa saurin DC, sarrafa dijital na kwamfuta maimakon sarrafa analog ya zama yanayin ci gaba.Matsakaicin saurin jujjuya mitar mota babbar hanya ce don adana kuzari, haɓaka aikin samarwa, haɓaka ingancin samfur, da haɓaka yanayin aiki.Tsarin saurin mitoci masu canzawatare da babban ingancinsa, babban ƙarfin wutar lantarki, da ingantaccen tsarin saurin gudu da aikin birki da sauran fa'idodi da yawa ana ɗaukar mafi kyawun tsarin saurin gudu.
Wanda ya gabatahigh-voltage inverter, wanda ya ƙunshi thyristor rectifier, thyristor inverter da sauran na'urori, yana da kasawa da yawa, manyan jituwa, kuma yana da tasiri akan grid na wutar lantarki da motar.A cikin 'yan shekarun nan, an ƙirƙira wasu sabbin na'urori waɗanda za su canza wannan yanayin, kamar IGBT, IGCT, SGCT da sauransu.Babban inverter wanda ya ƙunshi su yana da kyakkyawan aiki kuma yana iya gane inverter PWM har ma da gyara PWM.Ba wai kawai masu jituwa ba ne ƙanana, amma har ma da ƙarfin wutar lantarki yana inganta sosai
Fasahar sarrafa saurin jujjuyawar mitar AC shine haɗuwa da ƙarfi da rauni na wutar lantarki, fasahar haɗin kai da injina, ba wai kawai don magance jujjuyawar babbar ƙarfi ba (gyara, inverter), har ma don magance tarin bayanai, canji da watsawa. , don haka dole ne a raba shi zuwa iko da sarrafa sassa biyu.Na farko ya kamata ya magance matsalolin fasaha da suka shafi babban ƙarfin lantarki da ƙarfin halin yanzu, kuma na karshen ya kamata ya magance matsalolin software da hardware.Don haka, fasahar daidaita saurin jujjuyawar mitar wutar lantarki a nan gaba kuma za a haɓaka ta cikin waɗannan bangarorin biyu, babban aikinta shine:
