Ma'auni na ƙarfin lantarki, ko yawan ƙarfin lantarki ne, saboda idan lokacin shigar da bayanai, ko yanayin juyawa, da rashin daidaituwar ƙarfin lantarki ko yawan ƙarfin wutar lantarki yana da sauƙi ya sa na'urar ta ƙone.Ko kuma sashin wutar lantarki ya lalace, ko kuma motar ta juyo.

2.1.4 Kariyar Transformer.Thehigh ƙarfin lantarki inverter kawai kunshi uku sassa: Transformer hukuma, ikon naúrar hukuma, iko hukuma abun da ke ciki, transformer ne da yin amfani da tangential bushe irin gidan wuta don maida high-voltage alternating halin yanzu a cikin jerin daban-daban kusurwoyi na low irin ƙarfin lantarki samar da wutar lantarki naúrar, Ana iya sanyaya na'urar ta hanyar sanyaya iska ne kawai, don haka kariyar na'urar ta fi dacewa ta hanyar kariyar yanayin zafi, don hana zafin wutar lantarki ya yi yawa, kuma ya sa na'urar wutar lantarki ta kone.Ana sanya gwajin zafin jiki a cikin coil mai hawa uku na mai canzawa, kuma ɗayan ƙarshen binciken zafin jiki yana haɗa da na'urar sarrafa zafin jiki.Na'urar sarrafa zafin jiki na iya saita zafin farawa ta atomatik na fan a kasan na'ura mai canzawa, zazzabin ƙararrawa, da zafin tafiya.A lokaci guda, zazzabi na kowane nada lokaci yana nuna sau da yawa.Za a nuna bayanin ƙararrawa a cikin mahallin mai amfani, kuma PLC za ta ƙararrawa ko kariyar tafiya.

2.2 High ƙarfin lantarki inverter kanti kariya gefe

Kariyar layin fitarwa nahigh ƙarfin lantarki inverter shi ne kariyar gefen fitarwa na inverter da kaya, gami da kariyar overvoltage na fitarwa, kariyar wuce gona da iri, kariyar gajeriyar da'ira, kariya ta zafin jiki da sauransu.

2.2.1 Kariyar Ƙarfin Wutar Lantarki.Kariyar overvoltage na fitarwa yana tattara ƙarfin fitarwa ta hanyar allon samfurin ƙarfin lantarki a gefen fitarwa.Idan ƙarfin wutar lantarki ya yi yawa, tsarin zai yi ƙararrawa ta atomatik.

2.2.2 Fitowar Kariya ta wuce gona da iri.Kariyar wuce gona da iri tana gano fitarwar halin yanzu da Hall ya tattara kuma ya kwatanta shi don tantance ko yana haifar da wuce gona da iri.
