1. Kukula kwa msika
Ma capacitor a mafilimu amatchula ma capacitor okhala ndi mafilimu amagetsi amagetsi ngati ma dielectric. Malinga ndi njira zosiyanasiyana zopangira ma electrode, amatha kugawidwa m'magulu awiri: capacitor wa filimu ya foil ndi capacitor wa filimu yachitsulo. Malinga ndi kapangidwe kake ndi njira yogwiritsira ntchito, amagawidwa m'magulu awiri: mtundu wozungulira, mtundu wopaka, mtundu wopangira ndi mtundu wosapangira. Malinga ndi mtundu wa mphamvu yamagetsi, amatha kugawidwa m'magulu awiri: ma capacitor a filimu ya DC ndi AC.
Pakadali pano, makampani opanga mafilimu akulowa munthawi ya chitukuko chokhazikika kuyambira
nthawi ya kukula mofulumira, ndipo mphamvu yatsopano ndi yakale ya kinetic yamakampaniyi ili mu
gawo losinthira.

2. Kugwiritsa ntchito pansi pa madzi
Ma capacitor a mafilimu, omwe amagwira ntchito bwino kwambiri, amagwiritsidwa ntchito kwambiri m'mafakitale ambiri monga zida zapakhomo, kulumikizana, ma gridi amagetsi, kusintha kwa njanji, kuwongolera mafakitale, kuunikira ndi mphamvu zatsopano (photovoltaic, mphamvu ya mphepo, magalimoto). Ndi gawo loyambira lamagetsi, lomwe limagwiritsidwa ntchito pafupifupi m'mabwalo onse amagetsi.
●Gawo latsopano la magalimoto amphamvu
M'zaka zaposachedwapa, mfundo zomwe zilipo panopa m'magalimoto atsopano amphamvu zabuka motsatizana, ndipo mizinda yambiri yasonkhanitsa ndikulengeza mfundo zoyenera kuti ipange mwamphamvu kugwiritsa ntchito magalimoto atsopano amphamvu, zomwe pamapeto pake zidzalimbikitsa kufunikira kwakukulu kwa ma capacitor amafilimu. Malinga ndi deta yochokera ku China Association of Automobile Manufacturers, mu 2020, kupanga magalimoto atsopano amphamvu ku China kudzakhala mayunitsi 1.366 miliyoni, ndipo kuchuluka kwa malonda kudzakhala mayunitsi 1.367 miliyoni. Mu theka loyamba la 2021, kupanga magalimoto atsopano amphamvu ku China kunali mayunitsi 1.215 miliyoni, ndipo malonda anali mayunitsi 1.206 miliyoni.

Ma capacitor a mafilimu ndi ma capacitor omwe amagwiritsidwa ntchito posefera DC. Chifukwa chakuti ali ndi ubwino wokhala ndi moyo wautali komanso kukhazikika kwa kutentha bwino poyerekeza ndi ma capacitor achikhalidwe, ndi oyenera kusefera DC mu inverter m'magalimoto atsopano amphamvu. Popeza kugwiritsa ntchito ma capacitor a mafilimu m'magalimoto osakanikirana kwadziwika ndi msika, ma capacitor a mafilimu agwiritsidwanso ntchito kwambiri m'misika yamagalimoto atsopano amphamvu monga magalimoto amagetsi enieni.
Kuwonjezeka kosalekeza kwa malonda a magalimoto atsopano amphamvu kwabweretsa malo akuluakulu pamsika wa ma capacitor opanga mafilimu. Ngati kufunikira kwa ma capacitor opanga mafilimu atsopano amphamvu ndi zidutswa 1.5 pa unit ndipo mtengo wa unit ndi 450 yuan pa chidutswa chilichonse, kukula kwa msika wa ma capacitor opanga mafilimu m'munda watsopano wa magalimoto amagetsi ku China mu 2020 kudzakhala pafupifupi 922 miliyoni yuan.

●Mphamvu ya mphepo
Ma capacitor a mafilimu amagwiritsidwa ntchito mu ma converter a mphamvu ya mphepo ndi ma inverter a photovoltaic chifukwa cha mtengo wake wotsika, mphamvu yamagetsi yapamwamba, komanso moyo wautali.
Monga njira imodzi yofunika kwambiri yopangira magetsi obwezerezedwanso m'dziko langa, kupanga magetsi amphepo ndi njira yodziwika bwino kwambiri yopangira magetsi muukadaulo watsopano wamagetsi mdziko langa, kotero yakhala ikugwiritsidwa ntchito kwambiri m'dziko langa.
Mphamvu ya mphepo ndi ukadaulo wina wopanga mphamvu zongowonjezwdwanso ukupitilizabe kusintha, ndalama zikupitirirabe kuchepa, magwiridwe antchito azachuma akukwera kwambiri, ndipo pali malo ambiri oti pakhale chitukuko chamtsogolo. Mu 2020, mphamvu yatsopano ya mphamvu ya mphepo ku China idzawonjezeka ndi 178.4% pachaka, ndipo mphamvu yatsopanoyo idzafika pa ma kilowatts 71.67 miliyoni. Mu theka loyamba la chaka cha 2021, mphamvu yatsopano ya mphamvu ya mphepo ku China idzakhala ma kilowatts 10.84 miliyoni.

Malinga ndi "2021-2027 China Film Capacitor Industry Market Development Research and Investment Prospect Analysis Report" yomwe idatulutsidwa ndi Zhiyan Consulting, ngati mtengo wa ma capacitor a filimu m'munda wamagetsi amphepo ndi 25,000-27,000 yuan/MW, kukula kwa msika wa ma capacitor a mafilimu m'munda wamagetsi amphepo mu 2019 kudzakhala 669 miliyoni yuan, ndipo kukula kwa msika wa ma capacitor a mafilimu m'munda wamagetsi amphepo ku China mu 2020 ndi pafupifupi 1.792 biliyoni yuan.

●Mphamvu ya photovoltaic
Monga mtundu wa mphamvu yatsopano, mphamvu ya photovoltaic yakopa chidwi cha mayiko ambiri. Mphamvu zambiri za dzuwa ndi miyala ya silicon zomwe zili m'malo mwake zimapangitsa kuti makampani opanga mphamvu za dzuwa m'dziko langa azichita bwino kwambiri.
Ubwino wapadera monga kuchepetsa ndalama ndi kusinthasintha kwathandiza ma photovoltaic kukhala chisankho chofunikira kwambiri pakupanga magetsi atsopano pansi pa kukakamizidwa ndi zolinga zotulutsa mpweya wa carbon. Mu 2020, mphamvu ya photovoltaic yatsopano ku China inali ma kilowatts 48.2 miliyoni, ndipo mu theka loyamba la 2021, mphamvu yatsopano ya photovoltaic ku China inali ma kilowatts 13.01 miliyoni.
