1. Isikali semarike
Ii-capacitor zefilimu zibhekisa kwii-capacitor ezineefilimu ze-elektroniki zodidi lombane njengee-dielectrics. Ngokweendlela ezahlukeneyo zokwenziwa kwee-electrode, inokwahlulwa ibe yi-capacitor yefilimu ye-foil kunye ne-capacitor yefilimu yesinyithi. Ngokwesakhiwo esahlukileyo kunye nendlela yokucubungula, yahlulwe ngohlobo olujikelezayo, uhlobo olune-laminated, uhlobo lwe-inductive kunye nohlobo olungena-inductive. Ngokwehlobo lwamandla ombane, inokwahlulwa ibe ziintlobo ezimbini: ii-capacitor zefilimu ze-DC kunye ne-AC.
Okwangoku, imboni yee-capacitor zefilimu ingena kwixesha lophuhliso oluzinzileyo ukusuka kwi-
ixesha lokukhula ngokukhawuleza, kwaye amandla amatsha nadala e-kinetic oshishino akwi
isigaba sotshintsho.

2. Usetyenziso olusezantsi
Ii-capacitor zefilimu, ezisebenza kakuhle kakhulu, zisetyenziswa kakhulu kumashishini amaninzi afana nezixhobo zasekhaya, unxibelelwano, iigridi zamandla, utshintsho lwesitimela, ulawulo lwemizi-mveliso, ukukhanyisa kunye namandla amatsha (i-photovoltaic, amandla omoya, iimoto). Licandelo elisisiseko le-elektroniki, elisetyenziswa phantse kuzo zonke iisekethe ze-elektroniki.
●Intsimi yesithuthi esitsha samandla
Kwiminyaka yakutshanje, imigaqo-nkqubo yangoku kwicandelo lezithuthi zamandla amatsha iye yavela emva kwenye, kwaye izixeko ezininzi ziye zaqokelela zaza zapapasha imigaqo-nkqubo efanelekileyo yokuphuhlisa ngamandla ukusetyenziswa kwezithuthi zamandla amatsha, nto leyo eya kuthi ekugqibeleni ikhuthaze imfuno enkulu kwii-capacitors zefilimu. Ngokwedatha evela kwi-China Association of Automobile Manufacturers, ngo-2020, ukuveliswa kwezithuthi zamandla amatsha eTshayina kuya kuba ziiyunithi eziyi-1.366 yezigidi, kwaye umthamo wokuthengisa uya kuba ziiyunithi eziyi-1.367 yezigidi. Kwisiqingatha sokuqala sowama-2021, ukuveliswa kwezithuthi zamandla amatsha eTshayina bekuziiyunithi eziyi-1.215 yezigidi, kwaye ukuthengiswa bekuziiyunithi eziyi-1.206 yezigidi.

Ii-capacitor zefilimu zii-capacitor ezisetyenziswa kwizicelo zokucoca ze-DC. Ngenxa yokuba ineenzuzo zobomi obude kunye nokuzinza okuhle kobushushu xa kuthelekiswa nee-capacitor zemveli, ifanelekile ngakumbi kwi-inverter DC filtering kwizithuthi zamandla amatsha. Njengoko ukusetyenziswa kwee-capacitor zefilimu kwizithuthi ezixutyiweyo kuye kwaqatshelwa yimarike, ii-capacitor zefilimu zikwasetyenziswa kakhulu kwiimarike zezithuthi zamandla amatsha ezifana nezithuthi zombane ezicocekileyo.
Ukukhula okuqhubekayo kwentengiso yezithuthi ezintsha zamandla kuzise indawo ebanzi yokukhula kwemarike yee-capacitors zefilimu. Ukuba imfuno yee-capacitors zefilimu zezithuthi ezintsha zamandla yi-1.5 iziqwenga ngeyunithi nganye kwaye ixabiso leyunithi yi-450 yuan ngenxalenye nganye, ubungakanani bemarike yee-capacitors zefilimu kwicandelo lezithuthi ezintsha zamandla eTshayina ngo-2020 buya kuba malunga ne-922 yezigidi zeeyuan.

●Intsimi yamandla omoya
Ii-capacitor zefilimu zisetyenziswa kwii-converters zamandla omoya kunye nee-inverters ze-photovoltaic ngenxa yokuba zisebenza kakuhle, zisebenza kakuhle, kwaye zihlala ixesha elide.
Njengenye yezona ndlela zibalulekileyo zokuvelisa umbane ezivuselelekayo kwilizwe lam, ukuvelisa umbane ngomoya kukwayindlela evuthiweyo yokuvelisa umbane kubuchwepheshe obutsha bokuvelisa umbane kwilizwe lam, ngoko ke isetyenziswa kakhulu kwilizwe lam.
Amandla omoya kunye nezinye iindlela zokwenza amandla avuselelekayo ziyaqhubeka nokuphucuka, iindleko ziyaqhubeka nokuhla, ukusebenza kakuhle koqoqosho kuphuculwe kakhulu, kwaye kukho indawo enkulu yophuhliso lwexesha elizayo. Ngo-2020, amandla amatsha okufakelwa kwamandla omoya aseTshayina aya kwanda nge-178.4% unyaka nonyaka, kwaye amandla amatsha okufakelwa aya kufikelela kwi-71.67 yezigidi zee-kilowatts. Kwisiqingatha sokuqala sowama-2021, amandla amatsha omoya aseTshayina aya kuba yi-10.84 yezigidi zee-kilowatts.

●Intsimi yamandla e-Photovoltaic
Njengohlobo lwamandla amatsha, amandla e-photovoltaic atsale ingqalelo yamazwe amaninzi. Izixhobo ezininzi zamandla elanga kunye neendawo zokugcina i-silicon ore zibonelela ngemeko entle yophuhliso lweshishini lamandla elanga lelizwe lam.
Iingenelo ezikhethekileyo ezifana nokunciphisa iindleko kunye nokuguquguquka zincede ii-photovoltaics ukuba zibe lukhetho olubalulekileyo kuhlobo olutsha lokuvelisa umbane phantsi koxinzelelo lweethagethi zokukhupha ikhabhoni. Ngo-2020, amandla e-photovoltaic asandul’ ukufakwa eTshayina angama-48.2 ezigidi zee-kilowatts, kwaye kwisiqingatha sokuqala sowama-2021, amandla amatsha e-photovoltaic afakwe eTshayina angama-13.01 ezigidi zee-kilowatts.
