Kodi kusiyana pakati pa ma capacitor a aluminiyamu electrolytic ndi ma capacitor a polymer electrolytic ndi kotani?

Ponena za kusankha mtundu woyenera wa capacitor pa ntchito zamagetsi, zosankha nthawi zambiri zimakhala zochititsa manyazi. Mtundu umodzi wodziwika bwino wa ma capacitor omwe amagwiritsidwa ntchito m'mabwalo amagetsi ndi electrolytic capacitor. M'gululi, pali mitundu iwiri ikuluikulu: ma capacitor a aluminiyamu electrolytic ndi ma capacitor a polymer electrolytic. Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ya ma capacitor ndikofunikira kwambiri posankha capacitor yoyenera pa ntchito inayake.

Ma capacitor a electrolytic a aluminiyamuNdi ma capacitor a electrolytic omwe amagwiritsidwa ntchito kwambiri komanso odziwika bwino. Amadziwika kuti ali ndi mphamvu zambiri komanso amatha kuthana ndi mphamvu zamagetsi zambiri. Ma capacitor amenewa amapangidwa pogwiritsa ntchito pepala lodzazidwa ndi electrolyte ngati dielectric ndi aluminiyamu ngati ma electrode. Electrolyte nthawi zambiri imakhala chinthu chamadzimadzi kapena gel, ndipo ndi momwe electrolyte ndi aluminiyamu zimagwirira ntchito zomwe zimathandiza ma capacitor awa kusunga ndikutulutsa mphamvu zamagetsi.

Koma ma capacitor a polymer electrolytic, ndi mtundu watsopano komanso wapamwamba kwambiri wa electrolytic capacitor. M'malo mogwiritsa ntchito electrolyte yamadzimadzi kapena ya gel, ma capacitor a polymer amagwiritsa ntchito polymer yoyendetsa bwino ngati electrolyte, zomwe zimapangitsa kuti ikhale yokhazikika komanso yotsika mphamvu mkati. Kugwiritsa ntchito ukadaulo wa solid-state mu ma capacitor a polymer kungapangitse kuti pakhale kudalirika, kukulitsa nthawi yogwira ntchito, komanso kupereka magwiridwe antchito abwino mu ntchito zama frequency apamwamba komanso kutentha kwambiri.

Chimodzi mwa kusiyana kwakukulu pakati pama capacitor a electrolytic a aluminiyamundipo ma capacitor a polymer electrolytic ndi nthawi yawo yogwirira ntchito. Ma capacitor a aluminiyamu electrolytic nthawi zambiri amakhala ndi moyo waufupi kuposa ma capacitor a polymer ndipo amatha kulephera chifukwa cha zinthu monga kutentha kwambiri, kupsinjika kwa magetsi, ndi ripple current. Koma ma capacitor a polymer amakhala ndi nthawi yayitali yogwirira ntchito ndipo adapangidwa kuti azitha kupirira mikhalidwe yovuta yogwirira ntchito, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito pazinthu zovuta.

Kusiyana kwina kofunikira ndi ESR (kukana kofanana ndi mndandanda) kwa ma capacitor awiriwa. Ma capacitor a aluminiyamu electrolytic ali ndi ESR yokwera poyerekeza ndi ma capacitor a polymer. Izi zikutanthauza kuti ma capacitor a polymer ali ndi kukana kochepa kwamkati, zomwe zimapangitsa kuti ntchito ikhale yabwino pankhani yogwiritsira ntchito ripple current, kupanga kutentha komanso kutulutsa mphamvu.

Ponena za kukula ndi kulemera, ma capacitor a polymer nthawi zambiri amakhala ang'onoang'ono komanso opepuka kuposa ma capacitor a aluminiyamu omwe ali ndi mphamvu zofanana komanso mphamvu zofanana. Izi zimapangitsa kuti akhale oyenera kwambiri pazida zamagetsi zazing'ono komanso zopepuka, komwe malo ndi kulemera ndizofunikira kwambiri.

Mwachidule, ngakhale kuti ma capacitor a aluminium electrolytic akhala chisankho chokondedwa kwa zaka zambiri chifukwa cha kuchuluka kwa mphamvu zawo komanso kuchuluka kwa mphamvu zamagetsi, ma capacitor a polymer electrolytic amapereka zabwino zingapo pankhani ya moyo wautali, magwiridwe antchito, ndi kukula. Kusankha pakati pa mitundu iwiri ya ma capacitor kumadalira zofunikira zenizeni za ntchitoyo, monga momwe zimagwirira ntchito, malire a malo, ndi zofunikira pakugwira ntchito.

Mwachidule, ma capacitor a aluminium electrolytic ndi ma capacitor a polymer electrolytic ali ndi zabwino ndi zovuta zawo. Kuti musankhe mtundu woyenera kwambiri wa capacitor pa ntchito, ndikofunikira kuganizira mosamala zofunikira zenizeni ndi momwe ntchito yamagetsi imagwirira ntchito. Pamene ukadaulo ukupitilira, ma capacitor a polymer electrolytic akuchulukirachulukira chifukwa cha magwiridwe antchito awo abwino komanso kudalirika, zomwe zimapangitsa kuti akhale njira ina yabwino m'malo mwa ma capacitor a aluminium electrolytic achikhalidwe m'magwiritsidwe ambiri amagetsi.
