Capacitors vs Supercapacitors
Capacitors yog cov khoom siv tau zoo heev thiab tau siv dav hauv cov khoom siv hluav taws xob thiab hluav taws xob. Capacitor yog ib qho khoom siv uas muaj peev xwm khaws cov nqi thiab yog li lub zog. Lub super-capacitor yog ib qho khoom siv uas muaj peev xwm khaws tau cov nqi ntau dua li ib txwm siv lub capacitor. Ob qho tib si ntawm cov khoom no muaj kev siv dav thiab muaj txiaj ntsig zoo hauv kev tsim cov circuits nyuaj. Capacitors yog siv nyob rau hauv kev lag luam xws li hluav taws xob engineering, hluav taws xob engineering, computer tsim, lub zog cia thiab ntau yam hauj lwm. Nws yog ib qho tseem ceeb heev kom muaj kev paub zoo hauv cov kev xav tom qab capacitors thiab super-capacitors thiaj li ua tau zoo hauv cov haujlwm no. Hauv tsab xov xwm no, peb yuav tham txog dab tsi capacitors thiab super-capacitors yog, lawv cov kev siv, yuav ua li cas capacitors thiab super-capacitors raug tsim, ntau hom capacitors thiab super-capacitors, lawv qhov zoo sib xws thiab thaum kawg qhov sib txawv ntawm capacitors thiab super-capacitors.
Capacitors
Capacitors yog cov khoom siv los khaws cov nqi. Capacitors tseem hu ua condenser. Commercially siv capacitors yog ua los ntawm ob hlau foils dov rau hauv lub tog raj kheej nrog ib tug dielectric nruab nrab ntawm lawv. Lub capacitance yog cov cuab yeej tseem ceeb ntawm lub capacitor. Lub capacitance ntawm ib yam khoom yog ib qho kev ntsuas ntawm tus nqi ntawm cov khoom uas tuaj yeem tuav tsis tau tawm. Capacitance yog ib qho khoom tseem ceeb hauv ob qho tib si hauv hluav taws xob thiab electromagnetism. Capacitance kuj txhais tau tias yog lub peev xwm khaws lub zog hauv qhov hluav taws xob. Rau lub capacitor, uas muaj V voltage sib txawv nyob rau hauv cov nodes thiab qhov siab tshaj plaws tus nqi uas yuav muab khaws cia rau hauv lub system yog Q, lub capacitance yog Q / V, thaum tag nrho cov ntsuas nyob rau hauv SI units. Chav tsev ntawm lub capacitance yog farad (F). Txawm li cas los xij, nws tsis yooj yim siv xws li chav tsev loj. Yog li, feem ntau ntawm cov nqi capacitance yog ntsuas hauv nF, pF, µF thiab mF ntau. Lub zog khaws cia hauv lub capacitor yog sib npaug (QV2)/2. Lub zog no yog sib npaug rau kev ua haujlwm ntawm txhua tus nqi los ntawm qhov system summed. Lub capacitance ntawm lub kaw lus nyob ntawm thaj tsam ntawm daim phiaj capacitor, qhov kev ncua deb ntawm cov phaj capacitor, thiab qhov nruab nrab ntawm cov phaj capacitor. Lub peev xwm ntawm lub kaw lus tuaj yeem nce los ntawm kev ua kom thaj chaw, txo qhov sib txawv lossis muaj qhov nruab nrab nrog ntau dua dielectric permittivity.
Super-capacitors
Hluav taws xob ob txheej capacitors lossis EDLCs feem ntau hu ua super-capacitors. Super-capacitors feem ntau muaj lub peev xwm siab heev piv rau cov capacitors li qub. Lub capacitance ntawm lub super-capacitor feem ntau yog ob lossis peb qhov kev txiav txim ntawm ib txwm capacitor. Cov cuab yeej tseem ceeb uas tseem ceeb hauv lub capacitor yog lub peev xwm ceev lossis lub zog ceev. Qhov no yog hais txog tus nqi ntawm cov nqi uas tuaj yeem khaws cia rau ib chav tsev loj.
Qhov txawv ntawm Capacitors thiab Super-capacitors yog dab tsi?
• Super-capacitors muaj lub zog ceev heev dua li cov capacitors ib txwm.
• Super-capacitors siv ob txheej ntawm cov khoom siv dielectric sib cais los ntawm ib qho yooj yim insulator nto raws li dielectric nruab nrab, whereas ib txwm capacitors tsuas yog ib txheej ntawm cov khoom siv dielectric.
• Cov capacitors ib txwm pheej yig dua li super-capacitors feem ntau.
