Waa maxay farqiga u dhexeeya inductor iyo kuul magnetic | hel

Waxaa laga arki karaa qalooca sifada impedance ee kuul magnetic in inta jeer ee barta kala guurka ka hooseeya inductance, iyo inta jeer ee barta kala guurka ka sarreeyaa caabbinta. Shaqada inductance waa in ay muujiso buuqa, halka iska caabintu ay nuugtaa buuqa oo ay u beddesho kulayl. Maxay wadaagaan inductors iyo kuul birlabeedka? Maxay ku kala duwan yihiin? Aan raacno soosaarayaasha indha indheeyaha si aan u fahanno!

Farqiga u dhexeeya inductor iyo kuul magnetic

1. Dareemayaashu waa qaybaha kaydinta tamarta, iyo birta birlabku waa aaladaha beddelka tamarta (consumption). Shaandheeyayaashu waxay isticmaali karaan inductors iyo kuul, laakiin waxay isticmaalaan habab kala duwan. Shaandhaynta Inductor-ku waxay tamarta korantada u beddeshaa tamar birlab ah, taasoo u saamaysa wareegga laba siyaabood: iyadoo tamarta korantada dib ugu beddelaysa tamar koronto, iyo iyadoo dibadda u soo ifaysa-sida EMI(EMI). Intaa waxaa dheer, tamarta korantada ayaa loo beddelaa tamarta kulaylka iyada oo aan la faragelinin wareegga labaad.

2. Waxqabadka shaandhada inductor- ku aad ayuu ugu fiican yahay bandowga soo noqnoqda ee hooseeya, laakiin marka waxqabadka filtarku dhaafo 50Mhz, kuul birlabku wuxuu isticmaalaa qaybtiisa impedance si uu dhawaaqa soo noqnoqda sare ugu beddelo tamarta kulaylka, wuxuuna gaadhay hadafkii baabi'inta sare -dhawaaqa soo noqnoqda gabi ahaanba.

3. Marka laga eego dhinaca EMC (EMC), boodhadhka magnetic waxay u beddeli karaan qaylada soo noqnoqda ee tamarta kulaylka, si ay u yeeshaan caabbinta shucaaca wanaagsan. Inta badan waxaa loo isticmaalaa aaladaha ka-hortagga EMI-ga waxaana inta badan loo adeegsadaa in lagu shaandheeyo calaamadaha is-dhexgalka isticmaalaha. Shaandheeyaha tamarta ee qalabka saacada xawaaraha sare leh ee korkiisa.

4. Marka inductor iyo capacitor ay sameeyaan filtar hoose oo hooseeya, isku darka labadan qaybood ayaa soo saari kara is-xakameyn sababtoo ah labaduba waa qaybaha kaydinta tamarta; Kuulaha magnetic waa aaladaha kala daadiya tamarta mana abuuraan dareen-celin marka la shaqaynayo capacitors.

5. Guud ahaan, hadda la qiimeeyay ee inductor loo isticmaalo sahayda korontada waa mid aad u sarreeya, sidaas darteed wareegga korontada ee u baahan hadda sare, sida loo isticmaalo shaandhaynta moduleka korontada; Kuul magnetic waxaa guud ahaan loo isticmaalaa kaliya filtarrada awoodda heerka-chip (si kastaba ha ahaatee, waxaa jira qiimeyno waaweyn oo hadda suuqa ah).

6. Kuul magnetic iyo inductors labaduba waxay leeyihiin iska caabin DC ah, halka iska caabbinta dc ee kuul magnetic ay wax yar ka yar tahay waxqabadka shaandhaynta, markaa cadaadiska kala duwan ee kuul magnetic waa yar yahay marka loo isticmaalo shaandhaynta awoodda.

7. Marka loo isticmaalo shaandhaynta, hadda shaqaynaya ee inductor waa ka yar yahay kan hadda la qiimeeyay, haddii kale inductor-ku ma dhaawacmi karo, laakiin qiimaha inductance wuxuu noqonayaa mid eex.

Dhulka caadiga ah ee inductor iyo birlab magnetic

1. Hadda la qiimeeyay. Haddii wakhtiga hadda ee inductor-ku uu dhaafo wakhtiga la qiimeeyay, inductance-ku si degdeg ah ayuu u yaraan doonaa, laakiin inductor-ku qasab maaha in uu dhaawacmo, iyo kuul magnetic ee hadda shaqaynayaa uu ka badan yahay kan hadda la qiimeeyay, waxa uu sababi doonaa burburka birta birlabeedka.

2. Dc caabbinta. Marka loo isticmaalo khadka korontada, waxaa jira wakhti gaar ah oo khadka ah, haddii adkeysiga dc ee inductor ama birta magnetic lafteedu ay aad u weyn tahay, waxay soo saari doontaa hoos u dhac gaar ah. Sidaa darteed, dooro qalabka leh caabbinta DC hooseeya.

3. Qalooca sifada soo noqnoqda. Xogta wax soo saarka ee kubbadda induction iyo kubbadda magnetic waxay ku lifaaqan yihiin qalooca sifada soo noqnoqda aaladda. Si aad u dooratid qalabka saxda ah waxaad u baahan tahay inaad si taxadar leh u tixraacdo qaloocyadan si aad u doorato qalabka saxda ah. Marka la codsado, u fiirso inta jeer ee resonant.

Kor waxaa ku yaal hordhaca inductors iyo kuul magnetic, haddii aad u baahan tahay macluumaad dheeraad ah oo ku saabsan inductors, fadlan la xiriir alaab-qeybiyeyaasha xirfadleyda ah.
