Amandla AbunjiweAma-Inductor, kuhlanganiswe nedatha yakamuva yobuchwepheshe bemboni kanye namaphuzu okulawula ikhwalithi, lo mhlahlandlela uhlanganisa uhla olubanzi lokuqukethwe kusukela ezimisweni eziyisisekelo, izinqubo zezinto ezibonakalayo kuya ekukhetheni kwangempela kanye nokugwema izingibe, ukwenza izinqumo ezingcono ekwakhiweni kokunikezwa kwamandla. Ake siqhubeke nengxoxo kusukela esihlokweni esedlule (ngesikhathi sokugcina sixoxa ngemibuzo eyi-6)
7. Kuyini "ukwehluleka ukumelana nokucindezela"? (Inkinga enkulu ekukhetheni!)
Lona "umgodi ofihliwe" ongabhekwa kalula. Kukhona ungqimba oluvikelayo phakathi kwezingxenye zempuphu yensimbi ngaphakathi kwe-integrated bundled.i-inductor.
* Inkinga: Ezindaweni zokusebenza ezisebenza ngamandla aphezulu, ezivame kakhulu, uma amandla okuvikela enganele, ungqimba lokuvikela phakathi kwe-iron powder cores lungabhobozwa.
* Umphumela: Kufana nokuxhuma i-resistor ngokuhambisana kuyo yonke indawoi-inductor, okuholela ekwandeni okukhulu kokulahlekelwa yinhliziyo, ukushisa okukhulu, ngisho nokushiswa yizicucu.
*Gwema izingibe: Ezinhlelweni lapho i-voltage yokufaka idlula i-50V, qinisekisa njalo isilinganiso se-voltage se-i-inductornomkhiqizi, hhayi nje inani le-inductance.
8. Kuyini i-Isat ne-Irms? Yikuphi okufanele kucatshangelwe ngesikhathi sokukhetha?
Lezi yizipharamitha ezimbili ezibalulekile zamanje:
* I-Isat (Ugesi Ogcwala): Ugesi lapho i-inductance yehla iye esilinganisweni esithile (isb., 30%). Ukudlula leli nani kubangela ukwehla okungazelelwe kwamandla okugcina amandla e-inductor, okungase kuholele ekungazinzini kwe-power loop.
* Ama-Irms (ugesi we-RMS): Ugesi lapho izinga lokushisa lobuso le-inductor lifinyelela khona inani elithile (isb., 40°C), okunqunywa kakhulu ukulahleka kwethusi (DCR).
* Isimiso: Uma ukhetha, womabili amapharamitha kumele ahlangabezane nezimfuneko zesekethe.
9. Ingabe ukumelana ne-DCR okuphansi (i-DC resistance) kungcono ngaso sonke isikhathi?
Yebo. Uma i-DCR iphansi, ukulahlekelwa kwethusi kuncane, ukusebenza kahle kokuguqulwa kwamandla kuyanda, futhi kuyanda nokwenyuka kwezinga lokushisa. Kodwa-ke, ngevolumu efanayo, ukuphishekela i-DCR ephansi kakhulu ngokuvamile kusho ukwehla kokufakwa kwamandla, okudinga ukuguquguquka okusekelwe esimweni esithile sokusetshenziswa (kungakhathaliseki ukuthi kubeka phambili ukusebenza kahle okuphezulu noma isitoreji esikhulu samandla).
10. Indlela yokwahlulela ikhwalithi ye-i-inductor ?
Isinqumo sokuqala singenziwa ngamaphuzu alandelayo:
*Ukubukeka: Ubuso kufanele bube bushelelezi futhi bube bushelelezi, bungenazo izimbobo noma imifantu, futhi uqweqwe lwephini kufanele lukhanye.
*Amandla ephini: Amatheminali ahlanganisiwe kufanele aqine futhi angaphuki kalula.
*Ukumelana ne-solder: Ngemva kokugoqa kabusha, umzimba akufanele ube nokushintsha kombala noma imifantu esobala.
11. Kungani kungahlanganiswaama-inductorkwenziwe kube kuncane futhi kube mncane?
A: Ngenxa yobuchwepheshe be-powder metallurgy, ayidingi izikhala zokuhlanganisa i-magnetic core ezigciniwe njenge-inductors zendabuko, futhi isakhiwo sayo sincane kakhulu. Njengamanje, ubuchwepheshe bungafinyelela imikhiqizo emincane kakhulu enobukhulu obungaphansi kuka-0.5mm, okufanele kakhulu omakhalekhukhwini namadivayisi agqokwayo.
12. Iyini inqubo ye-“T-Core”?
Lobu ubuchwepheshe obuthuthukisiwe besakhiwo obuthuthukisa ukusatshalaliswa kwesekethe kamagnetic ngokusebenzisa ama-mold akhethekile kanye namasu okugoqa, okunciphisa kakhulu ukulahlekelwa kanye nokuthuthukisa ukusebenza kwemvamisa ephezulu kanye nokusebenza kahle kokusatshalaliswa kokushisa.
13. Ingabe i-inductor ehlanganisiwe izogqwala?
Izinto zokusetshenziswa ikakhulukazi ziyimpuphu zensimbi. Uma isembozo sokushisa (njenge-epoxy resin) ebusweni bomkhiqizo sifafazwa ngokungalingani noma sonakele, empeleni kukhona ingozi yokushiswa kanye nokugqwala ezindaweni ezinomswakama ophezulu kanye nezifutho zikasawoti. Ubuchwepheshe bokufafaza obuzenzakalelayo obusezingeni eliphezulu bungavimbela ngempumelelo le nkinga.
