Ku- chip common mode inductor , imikhiqizo ehlukene ingakhethwa ngokuya ngezici kanye nezidingo zosayizi. I-Gv Electronics, ifekthri ye-chip inductor , yabelana nawe ukuthi ungayikhetha kanjani ikhoyili elungile yokuminyanisa yemodi ye-COMMon ngokombono wesici.
Ungase Udinge Lezi Ngaphambi Kwe-oda Lakho
1. Isetshenziswa kanjani ukudluliswa okuhlukile kanye nemodi evamile yokuklinya amakhoyili
Ngaphambi kokuchaza izici zamakhoyili okuminyanisa emodi evamile, ake siqale sethule umqondo wesignali yemodi evamile kanye nesignali yemodi yokuhlukanisa.
Ukudlulisa okuhlukile kuyindlela esetshenziselwa ukudluliswa kwedatha ngesivinini esikhulu. Isibonelo, i-MIPI? esetshenziswa kukhamera nesikrini sokubonisa sama-smartphones, i-HDMI?, i-DisplayPort, ne-USB yamakhompyutha zonke izindlela zokudlulisa ezihlukene.
Emigqeni emibili yokudlulisela okuhlukile, isigaba somunye nomunye (esibonisa ukuphambuka kwe-voltage waveform kanye ne-waveform yamanje) ukudluliswa kwesignali okubuyiselwe emuva.
Lesi siginali ibizwa ngokuthi isignali yemodi yokuhlukanisa, futhi ukudluliswa kwedatha kwenziwa ngesignali yemodi yokuhlukanisa. (Imodi ehlukile kwesinye isikhathi ibizwa ngemodi ejwayelekile). Uma kuqhathaniswa namasignali emodi yokuhlukanisa, kukhona futhi isignali ebizwa ngokuthi isignali yemodi evamile, edluliselwa esigabeni esifanayo emigqeni emi-2.
Kuma-inductors emodi evamile yemigqa yesignali, isignali yemodi evamile isignali engadingeki, okungukuthi, umsindo, obizwa ngokuthi umsindo wemodi evamile.
Izimpawu zemodi ehlukile zixutshwa nomsindo wemodi evamile. Uma isignali ehlukanisayo yamukelwe, amasignali emodi yokuhlukanisa ayaqinisana, futhi umsindo wemodi evamile uyakhansela. Izindlela zokudlulisa ezihlukile ezifana nalezi azingenwa kalula nomsindo wemodi evamile.
Amasignali emisebe adluliswa ngokuhlukana abonwa kude, futhi amasignali abekwe phezu komunye nomunye. Ngalesi sikhathi, izimpawu zemodi yokuhlukanisa ziyakhansela, futhi umsindo wemodi evamile uyaqinisana. Okusho ukuthi, isengozini yomsindo wemodi evamile ukude.
Uma izinkinga zomsindo ezifanayo zenzeka, ikhoyili yokuminyanisa yemodi evamile ixhunywa ngochungechunge entanjeni yokudlulisa ehlukanisayo ukuze kususwe ngempumelelo umsindo wemodi evamile.
2. Ukuqonda izici zemodi evamile yokuminyanisa amakhoyili
Eqinisweni, umsindo wemodi yokuhlukanisa unciphile ngenxa yekhoyili yemodi evamile yokuminyanisa. Ngaphezu kwalokho, amasignali emodi yokuhlukanisa kanye nemodi evamile athola ukuncipha okuhlukile ngenxa yamafrikhwensi ahlukene. Izici zekhoyili yokuminyanisa yemodi evamile imelwe izici zokuvama kokulahlekelwa kokufakwa kwemodi yokuhlukanisa i-Sdd21 kanye nesignali yokufaka yemodi evamile Scc21. (I-Sdd21 ne-Scc21 ziyingxenye yepharamitha ye-S-port ye-4-port exubile)
Izici zemvamisa zokulahleka kokufakwa kwemodi evamile Scc21. Ukujula kokulahlekelwa kokufaka, kukhulu ukulahlekelwa. Uma iphakeme imvamisa yesiginali yemodi yokuhlukanisa, ukulahlekelwa kukhulu. Ukulahleka kokufakwa kwemodi evamile i-Scc21 iyijika elinesiqongo, futhi umphumela wokukhipha umsindo wemodi evamile uyahlukahluka kuye ngokuthi imvamisa.
Imvamisa yesiginali ye-chip common mode inductor yolayini wesiginali iyahlukahluka kuye ngendlela yokusebenzelana, futhi imodi evamile yokuklinya ikhoyili nayo iyashintsha ngokufanele.
Ukuthi ikhoyili yokuminyanisa imodi evamile ifanelekile yini kungahluzwa ngokuya nge-waveform yesignali yokudlulisela. Ngokuvamile, imvamisa yokunqanyulwa kwekhoyili yokuminyanisa yemodi evamile iphindwe kathathu ifrikhwensi yesignali yokucaciswa kokudlulisela okuhlukile. Okubizwa ngokuthi i-cutoff frequency imvamisa lapho ukulahleka kokufakwa kwemodi yokuhlukanisa kuba ngu-3 dB.
Kodwa-ke, noma ngabe kungaphansi kwezikhathi ezi-3, kunezinkinga eziningi ku-waveform yesignali, futhi lokhu kuyinkomba engcono kakhulu. (Ngenxa yokuthi izinga lekhwalithi yesiginali elifana nemephu yokubhoboza libalulwe kusixhumi esibonakalayo ngasinye, ekugcineni kuyehlulelwa ukuthi kufanelekile noma cha ngokwaleli zinga)
Ngakolunye uhlangothi, umsindo wenkinga kanye nemvamisa yawo kuyahlukahluka ukusuka kutheminali kuye kutheminali, futhi ngokufanele izici zemvamisa yokulahlekelwa kokufakwa kwemodi evamile evamile ziyashintsha ngokufanele.
Isibonelo, uma kwenzeka umsindo oweqa inani elilinganiselwe elishiwo yizinga lokulawula ukukhishwa, kuphumelela kakhulu ukukhetha leyo enokulahlekelwa okukhulu kokufakwa kwemodi evamile kubhendi yefrikhwensi yalowo msindo.
Ngaphezu kwalokho, umsindo wemodi evamile oboniswa ukudluliswa okuhlukile ungase uthinte kabi imisebenzi yayo yokuxhumana okungenantambo njenge-LTE ne-Wi-Fi. Kungacatshangwa ukuthi umsindo wemodi evamile yefrikhwensi efanayo njengokuxhumana okungenantambo kwenzeka, futhi uthi ithola lo msindo. Lokhu kubizwa ngokuthi ukuzwela kokwamukela okucindezelwe. Ngalesi sikhathi, ngokufaka ikhoyili yemodi evamile, ukuphuma komsindo wemodi evamile kungacindezelwa futhi ukuzwela kokwamukela kungathuthukiswa.
Okungenhla yisingeniso sezimpawu zama-inductors emodi evamile ye-SMD. Uma ufuna ukwazi okwengeziwe ngama-inductors e-SMD, sicela usithinte.
okukhethekile ekukhiqizeni izinhlobo ezahlukene zama-inductors embala, ama-inductors anobuhlalu, ama-vertical inductors, ama-tripod inductors, ama-patch inductors, ama-bar inductors, amakhoyili emodi evamile, ama-high-frequency transformers nezinye izakhi kazibuthe.
