A cikin inverter da Converter na gargajiya, na'urorin bas capacitors sune masu ƙarfin lantarki, amma a cikin sababbi, ana zabar capacitors na fim, menene fa'idodin capacitors na fim idan aka kwatanta da masu ƙarfin lantarki?

A halin yanzu, ƙari da ƙari masu karkatar da igiyoyi suna zabar capacitors na fim saboda dalilai masu zuwa:

(1) Fim capacitors iya cimma mafi girma ƙarfin lantarki jure fiye da electrolytic capacitors.Ƙimar wutar lantarki na aluminum electrolytic capacitors yana da ƙananan, har zuwa 450 V. Don samun ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin ƙarfin, yawanci suna buƙatar yin amfani da su a cikin jerin, kuma dole ne a yi la'akari da matsalar daidaitawar wutar lantarki a cikin tsarin haɗin layi.Sabanin haka, fim ɗin capacitors na iya isa har zuwa 20KV, don haka babu buƙatar yin la'akari da jerin haɗin kai a cikin aikace-aikacen matsakaici da matsakaicin ƙarfin lantarki, kuma ba shakka, babu buƙatar la'akari da matsalolin haɗin gwiwa kamar daidaitawar wutar lantarki da ƙimar da ta dace ma'aikata.

(2) Fim capacitors suna da mafi girman juriya na zafin jiki fiye da masu ƙarfin lantarki.

(3) Lokacin rayuwar capacitor na fim ya fi ƙarfin ƙarfin lantarki.Gabaɗaya, tsawon rayuwar capacitor na lantarki shine 2,000H, amma tsawon rayuwar capacitor na fim ɗin CRE shine 100,000H.

(4) ESR ya fi karami.ESR na capacitor na fim yawanci yana da ƙasa sosai, gabaɗaya ƙasa da 1mΩ, kuma inductance na parasitic shima yayi ƙasa sosai, kaɗan ne kawai na nH, wanda ba ya misaltuwa da masu ƙarfin lantarki na aluminum.Matsakaicin ƙarancin ESR yana rage ƙarfin ƙarfin lantarki akan bututun sauyawa, wanda ke da amfani ga aminci da kwanciyar hankali na bututun sauyawa.

(5) Stronger ripple halin yanzu juriya.The ripple halin yanzu juriya na metalized film capacitors iya zama goma zuwa da yawa dozin sau na rated ripple halin yanzu na aluminum electrolytic capacitors na guda iya aiki.Domin cimma mafi girma na juriya na yanzu, aluminum electrolytic capacitors yawanci suna amfani da ƙarfin da ya fi girma don saduwa da buƙatun, yayin da mafi girma ƙarfin shine sharar da ba dole ba na farashi da sararin shigarwa.
