Imowudi yokutsala eqhelekileyo , ekwabizwa ngokuba kukutshixwa kwemowudi eqhelekileyo, zihlala zisetyenziselwa ukuhambisa iiguquli kwiikhompyuter zekhompyuter ukugqitha imiqondiso yokuphazanyiswa kwendlela eqhelekileyo Kuyilo lwepaneli yolawulo, imo eqhelekileyo yiminxa yekhoyili ikwanomsebenzi wokucoca i-EMI, onokuthi thintela umbane wombane obangelwe sisantya esiphezulu samandla ombane ekuthumeleni kwimathiriyeli engaphandle enemitha.
Kutheni imo eqhelekileyo yokutshixeka kwe-EMI?
Ukukuqonda ngcono oku, kubalulekile ukuba uqale uhlalutye ukwakhiwa kweendlela eziqhelekileyo zokutshixwa.
Iifilitha zokupasa eziphantsi zendlela yokutshixwa yimo yesiqhelo ye-USB, iLa kunye neLb ziindlela eziqhelekileyo zokutshixwa Ikhoyili ezimbini zinenxeba kwikhoyili enye yenguqu nenani elifanayo lokujika kunye nee-engile zesigaba (ukubuyela umva kwe-coil inductor), ke, xa yonke imisinga yesiqhelo in Ukuhamba kwesekethe ngendlela eqhelekileyo yokutshixwa, imisinga enjalo yenza imagnethi kumacala ohlukileyo kwi-coil ye-inductor enesigaba esifanayo i-Angle kunye nokuchasana okwangoku.Kule ndawo, yonke imijelo yesiqhelo yedatha yesiqhelo ihlupheka ngokuxhathisa iikhoyili (kunye nenani elincinci Ukutshatyalaliswa kokutshatyalaliswa ngenxa yokuhamba kwe-inductance); Xa imo eqhelekileyo yangoku ihamba ngekhoyili, kuba imo eqhelekileyo yangoku ikwicala elinye, ikhoyili iya kwenza umazibuthe kwicala elinye, kunye nokuphendula okungahambisiyo kwekhoyili iya kwandisa, isenze i-coil iziphathe njenge-impedance ephezulu, nto leyo eya kukhokelela kulindelo olomeleleyo olulindelekileyo lokungeniswa.
Ke ngoko, imeko yangoku yokubonisa ebonakalayo iya kuncitshiswa kukungalingani ukufezekisa injongo yecebo lokucoca ulwelo.Ngokwenyani, ukuba isiphelo esinye sefilitha yokupasa esezantsi iqhagamshele kumqondiso wongenelelo kwaye elinye icala lixhume isixhobo esichaphazelekayo Kwaye umatshini, uLa no-C1, uLb kunye no-C2 baya kuvelisa iiseti ezimbini zeefilitha zokupasa ezisezantsi ezikwaziyo ukusebenzisa imowudi eqhelekileyo yokungenisa umbane kwindlela eya kwiimpawu eziphantsi kakhulu zokwahlulahlula.
Isekethe ayinakucinezela kuphela ukuhanjiswa kwembonakalo yangaphandle ye-electromagnetic induction, kodwa ikwacutha uphawu lwe-electromagnetic induction olubangelwa ngumgca wokucacisa ngokwawo ekusebenzeni komlingani, ngaloo ndlela kuncitshiswa ngokufanelekileyo ukwenzakala komqondiso wokuphazamiseka ngokuchasene namandla aqine.
Okwangoku, imo eqhelekileyo ekrwitshiweyo coil eyenziwe yinkampani inezibonelelo zokucinezelwa kwengxolo ephezulu kunye namanyathelo othintelo, ulwakhiwo oluqhelekileyo lwendlela yokuchwetheza, ukungahambelani kakuhle komqondiso, ubungakanani obuncinci, kulula ukuyisebenzisa, uzinzo oluhle, kulula ukuyisebenzisa kunye nomgangatho ophezulu Ukusetyenziswa ngokubanzi kwizixhobo zokulinganisela izandi zokulinganisela, i-multi-frequency transformer, i-impedance transformer, i-transformer ne-unbalanced transformer, njl.
Kukho i-usb ene-ferrite engundoqo yendlela eqhelekileyo yokuxinana kwe-coil / i-EMI ye-filter inductance, inezinto ezininzi ezinokuthambeka, ukuthintela ingxolo elungileyo kunye namanyathelo othintelo, uxinzelelo oluphezulu lwengxolo kunye nophawu lwedatha yendlela eyahlukileyo, ukunqanda isiginali yokuphazamiseka uphawu lwedatha yengxolo, isantya esiphezulu sedatha yesiphene hayi ukusilela, ubungakanani obuncinci, uzinzo olulungileyo, ukusebenziseka lula, izibonelelo ezikumgangatho ophezulu.
Iintambo ze-USB zeekhompyuter zobuqu kunye neepheripherali, IEEE1394 iintambo ze-DVC kunye neebhokisi ezisetiweyo zeTV, kunye nemiqondiso yeaudiyo yeepaneli zokusebenza zeLCD kunye nokusebenza kweevolthi ezantsi.
Oko kukwaziswa kwefilitha yokupasa esezantsi kwimowudi yokutswina eqhelekileyo. Ndiyathemba ukuba uyayithanda! Singumenzi , ukuba ufuna ukuthenga okanye ukwenza ngokwezifiso, wamkelekile ukubonisana ~
