E inductor , eo hape e tsejoang e le choke, e khetholloa ke "inertia e kholo" ea hona joale e phallang ho eona. Ka mantsoe a mang, ka lebaka la ho tsoela pele ha phallo, hona joale ho inductor e tlameha ho tsoela pele, ho seng joalo e tla hlahisa sekhahla se seholo sa motlakase. Inductor ke karolo ea makenete, kahoo ka tlhaho e na le bothata ba ho tlala matla a khoheli. Lisebelisoa tse ling li lumella inductance saturation, lits'ebetso tse ling li lumella li-inductors hore li kene ka botlalo ho tsoa ho boleng bo itseng ba hajoale, 'me lits'ebetso tse ling ha li lumelle li-inductors ho tlala, tse hlokang phapang lipakeng tsa lipotoloho tse itseng.
Maemong a mangata, inductor e sebetsa "sebakeng sa linear", moo inductance e leng teng kamehla 'me ha e fetohe ka motlakase oa motlakase le oa hona joale. Leha ho le joalo, ho na le bothata bo ke keng ba hlokomolohuoa, ke hore, ho pota-pota ha inductor ho tla lebisa ho mekhahlelo e 'meli e ajoang (kapa parasitic parameters), e' ngoe ke e ke keng ea qojoa ea ho hanyetsa, e 'ngoe ke ho ajoa ho kheloha ha capacitance ho amanang le ho tsubella. tshebetso le thepa.
Matla a Stray ha a na phello e fokolang hangata, empa butle-butle e hlaha ka keketseho ea maqhubu. Ha maqhubu a le ka holim'a boleng bo itseng, inductor e ka fetoha tšobotsi ea capacitive. Haeba capacitance e khelohileng "e tsepamisitsoe" ho capacitor, litšobotsi tsa capacitance ka mor'a maqhubu a itseng a ka bonoa ho tloha potolohong e lekanang ea inductor.
Boemo ba ho sebetsa ba inductor potolohong
Joalo ka ha capacitor e na le tefiso le ho lahla hona joale, inductor e boetse e na le ts'ebetso ea ho tjhaja le ho ntša motlakase. Matla a motlakase ho capacitor a lekana le motsoako oa hona joale, 'me hona joale ho inductor e lekana le motsoako oa motlakase. Ha feela motlakase oa inductor o fetoha, sekhahla sa phetoho ea di/dt le sona se tla fetoha; motlakase o eang pele o etsa hore ho phahama ha hona joale ka mokhoa o tšoanang, 'me motlakase o ka morao o etsa hore motlakase o fokotsehe ka mokhoa o itekanetseng.
Ho bohlokoa haholo ho bala inductance e nepahetseng ho khetha inductor e nepahetseng le capacitor ea tlhahiso ho fumana bonyane ba motlakase oa ripple.
Khetho ea inductance ea ho fetoha ha maemo ho theoha Phepelo ea motlakase
Ha u khetha li-inductors bakeng sa phepelo ea motlakase oa buck, hoa hlokahala ho tseba hore na boholo ba motlakase o kenang, motlakase o hlahisoang, maqhubu a ho fetoha ha matla, lebelo le phahameng la ripple hajoale le potoloho ea mosebetsi.
Khetho ea inductance ea boost switching Phepelo ea motlakase
Bakeng sa lipalo tsa matla tsa phepelo ea motlakase ea boost switching, ntle le hore kamano pakeng tsa duty cycle le inductance voltage e fetohile, ts'ebetso e 'ngoe e ts'oana le ea ho theola phepelo ea motlakase.
Ka kopo elelloa hore ho fapana le phepelo ea motlakase ea buck, matla a hona joale a phepelo ea matla a matla ha a fanoe ka linako tsohle ke motlakase oa motlakase. Ha tube ea switjha e ntse e tsoela pele, motlakase oa motlakase o phalla fatše ka tube ea switjha, 'me moroalo oa hona joale o fanoa ke capacitor ea tlhahiso, kahoo capacitor ea tlhahiso e tlameha ho ba le matla a lekaneng a ho boloka matla ho fana ka hona joale ho hlokahalang ke mojaro. nakong ena. Leha ho le joalo, nakong ea ho tima ha sesebelisoa, hona joale ho phalla ka inductor ha ho fane feela ka mojaro, empa hape ho lefella capacitor ea tlhahiso.
Ka kakaretso, ha boleng ba inductance bo e-ba kholoanyane, ripple e hlahisoang e tla fokotseha, empa karabelo e matla ea phepelo ea motlakase le eona e tla mpefala, kahoo khetho ea boleng ba inductance e ka fetoloa ho latela litlhoko tse khethehileng tsa kopo ea potoloho ho fihlella. phello e ntle ka ho fetisisa.
Ho eketseha ha maqhubu a ho fetola ho ka etsa hore inductance e be nyenyane, e le hore boholo ba 'mele ba inductor bo be bonyenyane' me bo boloke sebaka sa boto ea potoloho, kahoo motlakase o fetohang hona joale o na le mokhoa oa ho ba le maqhubu a phahameng, e le ho finyella litlhoko tsa tse nyenyane le tse nyenyane. boleng ba lihlahisoa tsa elektroniki.
E ka holimo ke kenyelletso ea ho khetha inductor e nepahetseng bakeng sa phepelo ea matla a ho fetola. haeba u batla ho tseba haholoanyane ka inductor, ka kopo ikutloe u lokolohile ho ikopanya le rona.
