Amandla AbunjiweyoAbaqalisi, kunye nedatha yamva nje yetekhnoloji yoshishino kunye neendawo zokulawula umgangatho, esi sikhokelo sigubungela uluhlu olubanzi lomxholo ukusuka kwimigaqo esisiseko, iinkqubo zezinto ezibonakalayo ukuya ekukhetheni ngokwenene kunye nokuphepha imigibe, ukwenza ukhetho olungcono kuyilo lombane. Masiqhubeke nengxoxo evela kwinqaku elidlulileyo (okokugqibela sixoxa ngemibuzo emi-6)
7. Yintoni "ukungaphumeleli kokumelana noxinzelelo"? (Ingxaki enkulu ekukhetheni!)
Le "yingxaki efihlakeleyo" ekulula ukuyihoya. Kukho umaleko wokukhusela phakathi kweentsimbi zomgubo wentsimbi ngaphakathi kwesixhobo esibunjiweyo esidibeneyo.i-inductor.
* Ingxaki: Kwiindawo zokusebenza ezisebenza ngamandla aphezulu, ezisebenza rhoqo, ukuba amandla okukhusela awanelanga, umaleko wokukhusela phakathi kweentsimbi zomgubo wentsimbi unokugqobhoka.
* Isiphumo: Kufana nokudibanisa i-resistor ngaxeshanye ngaphesheyai-inductor, nto leyo ebangela ukwanda okukhulu kwelahleko ezingundoqo, ubushushu obukhulu, kwanokutsha kweetships.
*Ziphephe iingxaki: Kwizicelo apho i-voltage yokufaka idlula i-50V, soloko uqinisekisa umlinganiselo we-voltage ye-i-inductorkunye nomenzi, kungekuphela nje ixabiso lokungenisa.
8. Zithini ii-Isat kunye nee-Irms? Zeziphi ekufuneka ziqwalaselwe xa kukhethwa?
Ezi ziiparameter ezimbini eziphambili zangoku:
* Isat (Umsinga Wokugcwala): Umsinga xa i-inductance yehla iye kwinani elithile (umz., 30%). Ukudlula kweli xabiso kubangela ukwehla ngequbuliso kwamandla okugcina amandla e-inductor, okunokukhokelela ekungazinzini kwi-power loop.
* I-Irms (umbane we-RMS): Umbane apho ukunyuka kobushushu bomphezulu we-inductor kufikelela kwixabiso elithile (umz., 40°C), ngokuyintloko kumiselwa kukulahleka kobhedu (DCR).
* Umgaqo: Xa ukhetha, zombini iiparameter kufuneka zihlangabezane neemfuno zesekethe.
9. Ingaba i-DCR ephantsi (i-DC resistance) isoloko ingcono?
Ewe. Okukhona i-DCR iphantsi, kokukhona ilahleko yobhedu incinci, kokukhona i-power conversion efficiency iphezulu, kwaye i-temperature effect iphantsi. Nangona kunjalo, kwi-volume efanayo, ukulandela i-DCR ephantsi kakhulu kuthetha ukunciphisa i-inductance, efuna i-trade-off ngokusekelwe kwimeko ethile yesicelo (nokuba kubekwe phambili ukusebenza okuphezulu okanye ukugcinwa kwamandla amakhulu).
10. Indlela yokugweba umgangatho we-i-inductor ?
Isigwebo sokuqala singenziwa ngala manqaku alandelayo:
*Inkangeleko: Umphezulu kufuneka ube tyaba kwaye uthambe, ungabi naziqhushumbisi okanye imifantu, kwaye uqweqwe lwephini lufanele lukhazimle.
*Ukuqina kwephini: Iitheminali ezifakwe i-solder kufuneka ziqine kwaye zingaqhekeki lula.
*Ukumelana ne-solder: Emva kokunyibilika kwakhona kwe-solder, umzimba akufuneki ube nombala ocacileyo okanye imifantu.
11. Kutheni inokuba idityanisiweii-inductorsyenziwe ibe ncinci kwaye ibe ncinci?
A: Ngenxa yetekhnoloji yokunyibilikisa isinyithi ngomgubo, ayifuni zikhewu zendibano yemagnethi ezigciniweyo njengee-inductors zemveli, kwaye ulwakhiwo lwayo luncinci ngakumbi. Okwangoku, itekhnoloji inokufezekisa iimveliso ezincinci kakhulu ezinobukhulu obungaphantsi kwe-0.5mm, ezifanelekileyo kakhulu kwiifowuni eziphathwayo kunye nezixhobo ezinxitywayo.
12. Yintoni inkqubo ye-“T-Core”?
Le yiteknoloji yolwakhiwo ephucukileyo ephucula ukusasazwa kwesekethe yemagnethi ngokusebenzisa iindlela ezikhethekileyo zokubumba kunye neendlela zokujika, nto leyo enciphisa ngakumbi ilahleko kwaye iphucula ukusebenza kwamaza aphezulu kunye nokusebenza kakuhle kokusasazwa kobushushu.
13. Ngaba i-inductor edibeneyo iya kugqwala?
Izinto ezisetyenziswa ngokwemvelo ikakhulu ziipowder zesinyithi. Ukuba i-insulation coating (efana ne-epoxy resin) kumphezulu wemveliso itshiziwe ngokungalinganiyo okanye yonakele, kukho umngcipheko we-oxidation kunye nokugqwala kwiindawo ezinomswakama ophezulu kunye ne-salt spray. Itekhnoloji yokutshiza ezenzekelayo esemgangathweni ophezulu inokuthintela ngempumelelo le ngxaki.
