Ho kenella ha motlakase
Ho kenella ha motlakase ke bokhoni ba karolo ea motlakase, joalo ka khoele ea terata kapa solenoid, ba ho boloka matla tšimong ea makenete ha motlakase o phalla ka har'a eona. Yuniti ea SI ea ho lekanya ho kenella ha motlakase ke Henry (H). Ho kenella ha motlakase hangata ho bontšoa ka letšoao la 'L' 'me ho ka baloa ho sebelisoa equation:
\[ L = \frac{N\Phi}{I} \]
Moo \(N\) e leng palo ea lipotoloho, \(\Phi\) ke phallo ea makenete, 'me \(I\) ke hona joale.
Ha e le hantle, inductor e na le khoele ea terata, hangata e entsoeng ka koporo, e kopantsoeng ka sebopeho se itseng, joalo ka solenoid kapa toroid. Ha motlakase o feta khoeleng ena, matla a makenete aa etsoa ho potoloha terata. Liphetoho motlakaseng ona li baka liphetoho tšimong ena ea makenete, ho latela Molao oa Faraday oa Induction ea Electromagnetic. Sena se baka induction ea electromagnetic, e hlahisang matla a electromotive (EMF) a hanyetsang phetoho ea motlakase.
Molao-motheo ona o bonahala haholo tšebelisong ea li-inductor lipotolohong tsa elektroniki. Li-inductor li ka sebelisoa ho sefa maqhubu a itseng, ho laola ho sisinyeha lipotolohong tsa LC, kapa e le likarolo tsa polokelo ea matla ho li-converter tsa motlakase. Tšebeliso e 'ngoe ea konkreite ke choke, e sebelisetsoang ho thibela AC ha e ntse e lumella DC ho feta.
Leha ho le jwalo, ha di-inductor tse ngata di bewa haufiufi, taba e le nngwe ya bohlokwa eo ho lokelang ho nahanelwa ka yona ke kgokelo ya makenete pakeng tsa tsona, e ka bakang tshusumetso e tshekaletseng. Mona ke moo di-transformer di bang tsa bohlokwa haholo.
transformer
Transformer ke sesebelisoa se fetolang motlakase ho tloha boemong bo bong ho ea ho bo bong se sebelisa molao-motheo oa induction ea motlakase. Transformer e na le likhoele tse peli kapa ho feta tse kobehileng ho potoloha motheo oa tšepe kapa thepa e 'ngoe ea ferromagnetic. Khoele ea mantlha e hokahantsoe le mohloli oa motlakase, 'me khoele ea bobeli e hokahantsoe le mojaro. Li-transformer li ka eketsa (ho phahamisa) kapa ho fokotsa (ho theola) motlakase ha ho hlokahala.
Molao-motheo oa ts'ebetso oa transformer o thehiloe ho Molao oa Faraday oa Induction ea Electromagnetic le Molao oa Lenz. Ha motlakase oa AC o phalla ka har'a coil ea mantlha, matla a makenete a fetohang a hlahisoa ho potoloha eona. Matla ana a makenete a fetohang a feta ka har'a ferromagnetic core ho ea coil ea bobeli. Ho ea ka Molao oa Faraday, matla a makenete a fetohang a tla baka EMF coil ea bobeli. Boholo ba motlakase ona o bakoang bo itšetlehile ka palo ea lipotoloho coil ea bobeli ha e bapisoa le coil ea mantlha, ho latela equation e latelang:
\[ V_s = \frac{N_s}{N_p} \times V_p \]
Moo:
– \(V_s\) ke motlakase o fetang khoeleng ya bobedi.
– \(V_p\) ke motlakase o fetang khoeleng ya mantlha.
– \(N_s\) ke palo ea lipotoloho khoeleng ea bobeli.
– \(N_p\) ke palo ea lipotoloho khoeleng ea mantlha.
Karolo ea Li-Transformer Mekhoeng ea Matla a Motlakase
Li-transformer li bapala karolo ea bohlokoa tsamaisong ea motlakase ea lefats'e ka bophara. E 'ngoe ea melemo e meholo ea ho sebelisa AC ke hore motlakase o ka fetoloa habonolo ho sebelisoa transformer. Mohlala, motlakase o hlahisoang ke lifeme tsa motlakase hangata o maemong a motlakase a tlase, empa o fetoloa ho ba motlakase o phahameng haholo bakeng sa phetiso ea sebaka se selelele. Ts'ebetso ena e fokotsa tahlehelo ea motlakase e bakoang ke khanyetso ea likhoele.
