Kwiintlobo ze-inverter kunye nokwahlukana

Ngokuxhomekeke kwiimfuno zakho kunye neemfuno, unokukhetha kwiindidi ezahlukeneyo ze-inverters.Ezi ziquka i-square wave, i-square wave elungisiweyo, kunye ne-inverter ecocekileyo ye-sine.Zonke ziguqula amandla ombane ukusuka kumthombo weDC ukuya kumbane otshintshanayo, osetyenziswa zizixhobo zombane.I-inverter inokulungiswa kwakhona ukuvelisa i-voltage oyifunayo.

Ukuba unomdla wokuthenga i-inverter entsha, kuya kufuneka ubale usetyenziso lwamandla lulonke lwezixhobo zakho zombane.Umlinganiselo wamandla ngokubanzi we-inverter uchaza ukuba angakanani amandla isixhobo esinokubonelela ngawo kumthwalo.Oku kudla ngokubonakaliswa ngeewatts okanye iikilowatts.Unokufumana kwakhona i-inverter enomlinganiselo ophezulu wamandla aphezulu, kodwa oku kuhlala kubiza kakhulu.

Enye yezona ntlobo zisisiseko ze-inverters, i-square wave inverter, iguqula umthombo we-DC ube yi-square wave wave AC output.Eli maza lisezantsi kumbane kwaye lisebenza ngoku, lisenza ukuba lilungele usetyenziso olunovakalelo oluphantsi.Ikwangoyena didi lwe-inverter lungabizi kakhulu.Nangona kunjalo, le fomu yamaza inokudala isandi esithi "humming" xa iqhagamshelwe kwisixhobo somsindo.Ayizifanelanga kakuhle izinto zombane ezibuthathaka kunye nezinye izixhobo.

Uhlobo lwesibini lwe-inverter, i-square wave elungisiweyo, iguqula umthombo we-DC ube ngumbane otshintshanayo.Isebenza ngakumbi kune-square wave, kodwa ayigudi kakhulu.Olu hlobo loguqulo-guqulo lunokuthatha imizuzu emininzi ukukhaba. Ayilokhetho lulungileyo kwizixhobo zombane ezifuna ukuqalisa ngokukhawuleza.Ukongeza, i-THD factor (i-harmonic distortion iyonke) ye-wave ingaba phezulu, yenza kube nzima kwizicelo ezithile.I-wave inokuguqulwa kwakhona ukuze ivelise i-pulsed okanye i-sine wave wave.

Ii-inverters zinokuyilwa ngeendlela ezahlukeneyo ze-topology zesekethe zamandla, nganye kuzo ijongana nemiba eyahlukeneyo.Iziguquli zingasetyenziselwa ukuvelisa amaza e-sine alungisiweyo, amaza agudileyo okanye aguquliweyo asisikwere, okanye amaza e-sine acocekileyo.Unokukhetha kwakhona i-inverter ene-voltage, eneempawu ze-buck-converter.Ezi ntlobo ze-inverters zincinci, zikhaphukhaphu, kwaye zingabizi kakhulu kuneziguquli ezisekwe kwi-transformer.

Abaguquli banakho ukhetho lokusebenzisa i-thyristor circuit.Isiphaluka se-thyristor silawulwa yi-capacitor ye-commutation, elawula ukuhamba kwangoku.Oku kuvumela i-thyristors ukunika amandla amakhulu okuphatha amandla.Kukho neesekethe zokutshintsha okunyanzeliswayo ezinokuthi zongezwe kwii-SCRs.

Uhlobo lwesithathu lwe-inverter, i-inverter ye-multilevel, inokuvelisa i-voltage ye-AC ephezulu kwizixhobo eziphantsi.Olu hlobo lwe-inverter lusebenzisa i-topology ezahlukeneyo zesekethe ukuze kuphuculwe ilahleko zokutshintsha.Ingenziwa njengoluhlu okanye isiphaluka esihambelanayo.Isenokusetyenziswa kwakhona kunikezelo lwamandla olulindileyo ukuphelisa utshintsho oludlulayo.

Ngaphandle kweentlobo zee-inverters ezikhankanywe ngasentla, unokusebenzisa i-inverter yokulawula iimoto eziguquguqukayo ukuphucula i-waveform kunye nokukuvumela ukuba ulungelelanise umbane wokuphuma.Olu hlobo lwe-inverter lunokusebenzisa iindlela ezahlukeneyo zokulawula iindlela zokuphucula ukusebenza kakuhle kwe-inverter.de.
