Inductor yeMowudi eqhelekileyo okanye Choke
Ukuba iperi yeekhoyili kwicala elifanayo linxeba elijikeleze umsesane wemagnethi owenziwe ngento ethile yamagnetic, xa ukutshintshwa kwangoku kudlula, i-magnetic flux yenziwa kwikhoyili ngenxa yokungeniswa kwe-electromagnetic.Kwimiqondiso yemowudi yokwahlula, ukuqukuqela kwemagnethi eyenziweyo kuyafana kubukhulu kwaye kuchasene kwicala, kwaye ezi zimbini ziyarhoxisa enye kwenye, zikhokelela kwimowudi encinci kakhulu yokuthintela okwenziwa ngumsesane wemagnethi.Kwimiqondiso yemowudi eqhelekileyo, ubukhulu kunye nesalathiso semagnethi ephumayo eveliswayo iyafana, kwaye ukubekelwa phezulu kwezi zibini kuphumela kwimowudi enkulu yokuthintela umsesane wemagnethi.Olu phawu lunciphisa impembelelo yendlela eqhelekileyo yokuthomalalisa kwiimpawu zemowudi yokwahlula kwaye inokusebenza kakuhle kokucoca ngokuchasene nengxolo yemowudi eqhelekileyo.
I-inductor yemowudi eqhelekileyo ngokuyimfuneko sisihluzo se-bidirectional: kwelinye icala, idinga ukuhluza indlela eqhelekileyo yokuphazamiseka kombane kumgca wesignali, kwaye kwelinye icala, ikwafuna ukucinezela uphazamiseko lwe-electromagnetic ngokwayo ekuphumeni ngaphandle ukunqanda. echaphazela ukusebenza okuqhelekileyo kwezinye izixhobo zombane kwindawo efanayo ye-electromagnetic.
Iinzuzo ezineenkcukacha ziboniswe apha ngezantsi:
(1) I-annular magnetic core ine-electromagnetic coupling efanelekileyo, isakhiwo esilula kunye nokusebenza kakuhle kwemveliso;
(2) I-frequency ephezulu yokusebenza, ukuxinana kwamandla aphezulu, ukuphindaphinda phakathi kwe-50kHz ~ 300kHz.
(3) Iimpawu ezigqwesileyo zokutshatyalaliswa kobushushu, kunye nommandla ophezulu ukuya kumlinganiselo wevolumu, umjelo omfutshane kakhulu wokushisa, olungele ukutshatyalaliswa kobushushu.
(4) Ilahleko yokufakela ephantsi kakhulu;
(5) Uphawu oluphezulu lwe-impedance ye-high-frequency inductance;
(6) Umgangatho olungileyo kunye neendleko ezifanelekileyo;
(7) Isakhiwo esizinzileyo.
(1) Ukusebenzisa i-high frequency ferrite core, ukujika okuthe nkqo kocingo olusicaba;
(2) Iiparamitha zokusabalalisa okufanayo kunye nokuhambelana kakuhle kweeparamitha;
(3) Imveliso ngokuzenzekelayo kunye ne-inductance enkulu yangoku kunye nephezulu inokufezekiswa;
(4) Ngokusebenza okuphezulu kwangoku kunye nokugqwesileyo kwe-anti-EMI;
(5) Ukuthotyelwa kweeparamitha ezisasaziweyo;
(6) Uxinaniso oluphezulu lwangoku, i-frequency ephezulu, i-impedance ephezulu;
(7) Ubushushu obuphezulu beCurie;
(8) Ukunyuka kweqondo lokushisa eliphantsi, ilahleko ephantsi, njl.
Iqhele ukusetyenziswa kwikhompyuter yokutshintsha izixhobo zombane ukucoca imowudi eqhelekileyo yeempawu zokuphazamiseka kombane.Kuyilo lwebhodi, ii-inductors zemowudi eqhelekileyo zikwasebenza njengezihluzi ze-EMI ukucinezela i-radiation kunye nokukhutshwa kwamaza ombane we-electromagnetic oveliswa yimigca yemiqondiso enesantya esiphezulu.
Isetyenziswa kakhulu kwi-air conditioner yamandla, umbane weTV, umbane we-UPS, njl.
