Bakeng sa ho hlokomela ts'ebetso e fapaneng ea lebelo la enjene, theknoloji ea inverter e sebelisoa haholo ho enjene e sa phatloheng.Joalo ka sesebelisoa, inverter e ka fetola phepelo ea matla a maqhubu a matla (50Hz kapa 60Hz) hore e be phepelo e fapaneng ea maqhubu a AC, e le ho fihlela ts'ebetso ea lebelo le fapaneng la enjene.Sesebelisoa se kenyelletsa potoloho ea taolo bakeng sa ho laola potoloho e kholo;Rectifier circuit bakeng sa ho fetola alternating current ho ea ho ea hona joale;Potoloho ea bohareng ea DC e sebelisetsoa ho boreleli le ho sefa tlhahiso ea potoloho ea rectifier;Potoloho ea inverter, e sebelisetsoang ho fetolela motlakase o otlolohileng hore e be oa hona joale o fapanyetsanang.Li-converter tse ling tse hlokang ho etsa ts'ebetso e ngata, ho boetse hoa hlokahala ho hlomelloa ka CPU bakeng sa lipalo tsa torque le potoloho e tsamaellanang.Ka ho fetola maqhubu a phepelo ea matla a stator winding ea enjene, taolo ea lebelo le fapaneng e ka lemoha sepheo sa taolo ea lebelo.
Inverter Ho latela mekhoa e fapaneng ea ho arola, e ka aroloa ka inverter ea mofuta oa voltage le mofuta oa hona joale oa mofuta, PAM control inverter, PWM control inverter le high carrier frequency control PWM inverter, V / f control inverter, slip frequency control inverter le vector control inverter, Kakaretso. inverter, inverter e khethehileng ea ts'ebetso e phahameng, inverter e phahameng ea maqhubu, inverter ea mohato o le mong le inverter ea mekhahlelo e meraro, joalo-joalo.
Ho converter frequency, VVVF e bua ka ho fetoha ha voltage le frequency, ha CVCF e bua ka voltage e sa fetoheng le maqhubu a sa feleng.Ho phepelo ea motlakase ea AC e sebelisoang linaheng ho pota lefatše, ebang ke malapeng kapa lifekthering, motlakase le maqhubu hangata ke 400V/50Hz kapa 200V/60Hz(50Hz).Sesebelisoa se fetolang phepelo e joalo ea motlakase hore e be motlakase oa motlakase oa AC kapa maqhubu a motlakase se bitsoa "frequency converter".Bakeng sa ho hlahisa li-voltage le maqhubu a fapaneng, sesebelisoa se hloka ho fetolela alternating current ho direct current (DC).
Frequency converter e sebelisoa ho laola enjene mme e ka fetola motlakase le maqhubu.Ho latela polelo ea lebelo la enjene ea AC, lebelo la n le lekana le frequency f, 'me lebelo la enjene le ka fetoloa hafeela frequency f e fetoha.Ka hona, converter ea frequency e hlokomela taolo ea lebelo ka ho fetola maqhubu a phepelo ea motlakase, e leng mokhoa o sebetsang hantle haholo le taolo ea lebelo le phahameng la ts'ebetso.
Nts'etsopele ea li-converter tsa frequency, mekhoa e fapaneng ea taolo e bile teng, ho kenyelletsa:
Sinusoidal pulse width modulation (SPWM) mokhoa oa ho laola, moo 1U/f=C;
Mokhoa oa ho laola sebaka sa motlakase (SVPWM);
Mokhoa oa ho laola Vector (VC);
Mokhoa o otlolohileng oa taolo ea torque (DTC);
Matrix intersection - mokhoa oa ho laola mateano, joalo-joalo.
Ka holimo, ho hlalositsoe ts'ebeliso e ncha ea inverter mochining o thibelang ho phatloha.Ka theknoloji ea inverter, lebelo la enjene le ka fetoloa habonolo, la tlisa ts'ebetso e phahameng le tharollo ea matla a ts'ebetso e phahameng lebaleng la indasteri.
