Maqhubu converter bakeng dilenaneo tshielano: bolokong bo-thalo le dikarolo tse khōlō

Dirisega maqhubu converter bakeng tshielano dilenaneo ka Maemong a seng makae. Pele, ho fetola male rotor chenchana lebelo. Tabeng ya bobedi, bakeng sa ho kenya tshebetsong Litlhophiso tse kang nako ea matsapa le deceleration, liphetoho tse ka tekanyo e sa tšireletso. Ea boraro, ho fetola e le 'ngoe-mohato gagamalo tharo-mohato. Ha kamehla le monyetla oa ho hlokomela le matla a ya enjene induction ho tswa ho marangrang a mararo-mohato. E leng, ho joalo khokahano e hlokehang bakeng sa tshebetso e nepahetseng le tshebetso Optimum. Ka bomalimabe, ho etsa tharo-mohato gagamalo ke ho le thata ka ho lekaneng ka malapeng. A inverter maqhubu a lumella matla a tšoanetseng engine.

sethaleng rectifier

converter efe kapa efe, esita le rarahaneng ka ho fetisisa ka sebopeho, e entsoe ka ho na le masakana a 'maloa. Pele - le sethaleng rectifying eo sebeletsa ho sokolla lenaihana ho DC. Ho itšetlehile ka ya netweke le e leng matla a hlahisoang, ho ke ho hlokahala hore ho sebelisa lipotoloho fapaneng rectifier. Kahoo, ha kenyelletsoa e le 'ngoe-mohato fapanyetsana marangrang jwale ho lekane ho sebelisa halofo-e tsokoang rectifier. Re lokela ho hlokomela hore e male rotor tsa dilenaneo induction e shorted chenchana, kahoo le matla a ke keng a hlokahala.

Ho ka etsahala hore ba hlokomele le e le 'ngoe semiconductor diode. Empa e na le litšobotsi tse molemo rectifier borokho: tlase gagamalo tahlehelo. Ka semiconductor silicon e sebediswa. Haeba u etsa qeto ea ho etsa maqhubu a bona converter bakeng sa dilenaneo induction, ho rectifier likarolo ho hlokahala hore ho phetha tlhopho ya boholo ba khutlisetsang conduction jwale. Sena se tla ntlafatsa litšobotsi tsa sesebediswa.

Mora sethaleng rectifier lokela sefa unit trust. Ka mothofatso bonolo ke bottom (bipetsa) kenyelelitsoe lekhalo mmoho. Pakeng tsa mmoho le ho tloswa lithuto electrolytic capacitor. Le eona e neng e tšoaretsoe ho tlosa dikarolo tsohle polygonal tse setseng ka gagamalo phosollwa. Ka lebaka leo, ho ripple tsohle tlosoa. Ha o amahanya khumo ea filtara ho oscilloscope le sheba ho hlokomela e, u ka bona hore mela li otlolohile, ntle le liphetoho tse sa hlokahaleng.

Empa sekemeng tsa dilenaneo induction ke hore e ka feela ho tsamaisoa ke fapanyetsana jwale. A ile a etsa hore ka ea kamehla filtara khumo. Ka hona, ho hlokahala ho khutlela lesakaneng tsohle feletseng, ho etsa lenaihana tloha DC. Ho feta moo, molemo oa oona e lokela ho ba 220 volts (lekanya pakeng mohato le ho se nke lehlakore). tse ngata tsa mekhahlelo e - tse tharo. Feela tlas'a boemo ena e tla fana ka induction dilenaneo mosebetsi tsela e tloaelehileng.

mothating ona o sebeletsa ho sokolla DC ho lenaihana. Ho ka le literata ena, o ka lokisa le fetola litlhophiso tsa morao-rao tsa khumo le. Inverter Base - matla a ena transistors. Leha e le efe ea kajeno maqhubu converter bakeng tshielano dilenaneo ka sethaleng sena kenyelletsa ditokiseletso kopano tse tsheletseng IGBT-transistors. Kakaretso ea tshebediso ya semiconductors tse peli bakeng sa e mong le e mohato. Di khona motheong oa kenyelletsoa ha lintlha tsa pn-junctions hlahiswang ka tsela e tšoanang. A le makhatheng a mabapi bona mohato tharo tlosoa. Sena se totobatsoa ke le litšoantšo mehaho ka holimo.

Ka proizvodnje ya maqhubu converter kapa mosebetsi oa ho lokisa e hlokahalang ho phetha go tlhophiwa oa liboka tsa matla a ho ea ka khumo jwale. Mohlomong ke khetho feela, e leng lokela ho ketekoa. O lokela ho boela re hlahlobe monyetla oa tsamaiso microprocessor taolo. Hase bohle ba ka phuthehong ea transistors dumella ho fetola litšobotsi tse itseng tsa sethaleng inverter. Ka hona, ha khetha transistors matla ele hloko le monyetla oa ho taolo.

E thehiloe ka microcontroller bonolo, eo e fana ka tsamaiso eohle. Ena ke ladica i tse nyenyane tseo ka 'na e le lithakhisa 16 le 32,' me 64, 'me e itšetlehile 128. All ka palo ea likoung input-khumo fumaneha. Ho laola maqhubu converter ke ho hlokahala hore ho ho laola entsprechen 'maloa. Pele, ho hlahisa HAEBA shutdown ha feteng mocheso oa 'mele. Tabeng ya bobedi, e kenyeletsa Fans ha itseng boleng mocheso. Boraro, teko e etsoa bakeng sa e mong le e mohato jwale ya sethaleng khumo. The maqhubu a ya enjene induction ho fetoloa, sena se etsoa sebedisa sete polygonal resistor.

Sireletsa maqhubu inverter

Ha taolo mocheso o entsoe ka e hlahlobang bonolo, ea ntan'o ba ho sireletsa le tlhokahalo jwale ho sebelisa baru khethehileng. Ba ba bitsoa - baru jwale. Sena kela nyenyane oa potoloho a khoheli, eo e ntse e feta ka mohato khumo. Ka lebaka leo, re ka feela etsa-tharabololo le bonolo, e leng tla tšohloa mona ka tlase. Mabapi le mesebetsi mananeo, bakeng sa morero ona ho ke ke ho hlokahala hore ho fana ka mabapi le microcontroller ya dikonopo tse seng kae le mabitso a batho bao ka tsela e tloaelehileng bulehileng.

Le ho etsa thepa ea ka koloi e tla lokela ho sebelisa e ngata tsebo, ho akarelletsa le mananeo. Mohlala, maqhubu converters bakeng Motors tlameha ho sireletsoa. Ka lebaka leo, ka ba lokisetsa ho ea e-tharabololo ba tsamaiso microcontroller taolo lokela ho laela entsprechen itseng eo sesebediswa tripping. Mohlala, boleng moedi e bontšoa ka sesebediswa mocheso oa 'mele,' me hona joale e phallang ka e mong le e mohato ka khumo ea.

Hape, ka kōpo hlokomela hore lefela boleng ba morao-rao oa chesa ka mohato o le mong feela (ho nka hore ba bang ba nako e telele) e lokela ho lithuto tsa theoha. Ka mabaka ana 'ohle, ho hlokahala hore ho etsa-tharabololo, e leng e bolokwa ka microcontroller ena. Ke ka morero ona 'me sesebediswa tla sebetsa.

Maqhubu converter bakeng sa dilenaneo tshielano lokela hape fetola male rotor chenchana lebelo. Polygonal resistor li amana ka tsela e divider gagamalo ho koung input-khumo. The-tharabololo lokela ho hlokomela hore ha phetoho ena ea ho hanyetsa ka input molaoli eo ke ho hlokahala hore ho eketsa kapa fokotseha male rotor lebelo.
