Ungakhetha kanjani i-inductor yemodi evamile?
Ungakhetha kanjani umongo we-inductor wemodi evamile?,
,
Ulayini wamandla we-CM chokes ufinyelela ukucindezelwa okuphezulu kokuphazamiseka kwe-asymmetric, ngisho nasezindaweni eziphansi zamafrikhwensi. Ungayibukeli phansi imiphumela ye-parasitic uma usebenzisa ukuminya kwemodi evamile. Leli bekuyiphuzu elibaluleke kakhulu lokunciphisa lezi zinkokhelo lapho kwakhiwa uchungechunge lwe-WE-CMB. I-core / winding-ratio ephelele inika amandla amaza aphezulu kakhulu ezindaweni eziqhathanisekayo, noma kanjani i-inductance yanele. I-wire gauge elungisiwe ibona ukushisa okuphansi.
Izinzuzo:
1. Umklamo ohlangene kakhulu
2.Umkhiqizo wenze ngezifiso ngokusho kolwazi oluyisisekelo oluvela konjiniyela bakho. Isikhathi sokuhola esisheshayo sesampula.
3.Amazinga aphezulu okuphepha nokuthembeka
4. Ukuhlunga amasignali okugxambukela we-electromagnetic mode evamile
5.Kuwusizo kuhlelo lokusebenza oludinga ukuthi inductance ihluke ngezinguquko zamanje zomthwalo.
6.Self electromagnetic shielding. Isicelo esilula sokuguqula ibhodi le-PC.
7.Yakha ku-ROHS ukuthobelana.
Empeleni i-inductor yemodi evamile iyisihlungi esinezinhlangothi ezimbili: ngakolunye uhlangothi, kufanele ihlunge ukuphazanyiswa kwemodi evamile kagesi emugqeni wesignali, futhi ngakolunye uhlangothi, kufanele izicindezele ekukhipheni ukuphazamiseka kazibuthe ukugwema ukuthikameza okujwayelekile. ukusebenza kwezinye izinto zikagesi endaweni efanayo ye-electromagnetic.
Ama-inductors emodi evamile anokufinyeleleka okuphezulu kakhulu kwasekuqaleni, i-impedance enkulu kanye nokulahlekelwa kokufaka ngaphansi kwamandla kazibuthe womhlaba, futhi anomthelela omuhle kakhulu wokucindezela ekuphazamiseni, futhi abonisa izici zokulahlekelwa kokufaka okungenayo i-resonance ebangeni elibanzi lefrikhwensi. I-permeability yokuqala ephezulu: izikhathi ezingu-5-20 ze-ferrite, ngakho-ke inokulahlekelwa okukhulu kokufaka, futhi umphumela wayo wokucindezela ekuphazamisekeni kwe-conduction mkhulu kakhulu kune-ferrite.
Usayizi nobukhulu:
| Into | A | B | C | D | E | F | G |
| Usayizi(mm) | 14 Max | 10.5Ubukhulu | 16Ubukhulu | 3.5±0.5 | 4.5±0.3 | 10±0.3 | 0.7±0.2 |
Izakhiwo zikagesi:
| Into yokuhlola | Okujwayelekile | |
| I-inductance | WL W2 | 1.95111H Min@10KHz 0.05V SER @25°C |
| Amatheminali anamachashazi | 1.4 | |
| Isilinganiso sokuphenduka | Wl, W2 | 1:1 |
| Hi-Pot | Wl. W2 | Akukho ukuhlukaniswa kwe-1000XAC 2mA 2S |
Isicelo:
1.Amandla kagesi.
2.Umugqa wamandla ngaphakathi nesihlungi esiphumayo, ukushintsha ukunikezwa kwamandla.
3.Okufakwayo kolayini wamandla kanye nesihlungi esiphumayo
4. Ukucindezelwa kweziphazamiso zomsakazo ezimotweni
I-5.TV nezinto ezilalelwayo, ama-buzzers namasistimu we-alamu.
6. Kwenzelwe amasignali aqhumayo
7.Ukucindezelwa kokuphazanyiswa komsakazo kumamothoLapho kukhethwa indikimba kazibuthe yesixhumi semodi evamile, umumo, usayizi, ibhendi yefrikhwensi esebenzayo, ukukhuphuka kwezinga lokushisa kanye nentengo kufanele kucatshangelwe. Ama-cores kazibuthe asetshenziswa kakhulu amise okwe-U, amise okwe-E kanye ne-toroidal. Uma sikhuluma nje, ama-toroidal cores ashibhile ngoba i-toroid eyodwa kuphela engenziwa. Ezinye izimo zama-magnetic cores kumele zibe nokupheya okuzosetshenziselwa ama-inductors emodi evamile, futhi lapho akha, kucatshangelwa ukubhanqa kwama-cores amabili kazibuthe, kuyadingeka ukwandisa inqubo yokugaya ukuze kutholwe ukufinyeleleka okuphezulu kazibuthe. Ngakho; uma kuqhathaniswa nezinye izimo ze-magnetic cores, ama-toroidal cores anokufinyeleleka okuphezulu okusebenzayo kazibuthe, ngoba lapho amapheya amabili ezimongo kazibuthe ehlanganiswa, umcimbi wegebe lomoya awukwazi ukuqedwa kungakhathaliseki ukuthi umsebenzi wenziwa kanjani, ngakho-ke amandla kazibuthe asebenzayo aphakeme lokho kwengqikithi eyodwa kazibuthe emise okuvaliwe. Ingqikithi kufanele ibe phansi.
