Kukonza magwiridwe antchito a PCS converter - kukwaniritsa kusintha kwamphamvu bwino mumakina osungira mphamvu: YMIN film capacitors

Kusunga mphamvu kumatanthauza njira yozungulira yosungira mphamvu kudzera mu sing'anga kapena chipangizo ndikuchitulutsa pakafunika kutero mtsogolo. Machitidwe osungira mphamvu amachita gawo lofunika kwambiri m'makina atsopano amakono amagetsi. Ma inverter osungira mphamvu amachita gawo losintha mphamvu, kuwongolera ndi kulumikizana mumakina, komanso kuyitanitsa ndi kutulutsa mphamvu mbali zonse ziwiri kuti apititse patsogolo kugwiritsa ntchito mphamvu moyenera.

Zosinthira mphamvu nthawi zambiri zimakhala ndi ma input end, output end ndi control system. Pogwira ntchito ndi power grid, ma capacitor okhala ndi mphamvu zambiri, okana ma current shocks akuluakulu, ndi ESR yotsika amagwiritsidwa ntchito makamaka kuchita ntchito monga kukhazikika kwa voltage ndi kusefa, kusunga mphamvu ndikutulutsa kuti DC pulsations ikhale yosalala, motero kuwonjezera magwiridwe antchito a converter ndi kukhazikika kwa magwiridwe antchito a system yosungira mphamvu, komanso kuteteza converter ikakumana ndi zovuta zogwirira ntchito.

1. Kuchuluka kwa capacitance

Ma capacitor a filimu ya MDPali ndi makhalidwe a capacitance density yapamwamba, yomwe ndi yofunika kwambiri kuti PCS isunge mphamvu yotuluka yokhazikika panthawi yosintha mphamvu. Mu katundu monga ma mota, omwe akukumana ndi kufunikira kwa mphamvu, ma capacitor a filimu amapereka mphamvu yobwezera mphamvu, kukhazikika kwa mphamvu, ndikukweza magwiridwe antchito a ma mota, motero kukweza mphamvu zogwirira ntchito komanso kukhazikika kwa makina osungira mphamvu.

2. Kudalirika kwambiri komanso moyo wautali

Poyerekeza ndi ma capacitor a aluminiyamu achikhalidwe, ma capacitor a YMIN film amakhala ndi nthawi yayitali yogwira ntchito komanso kudalirika kwambiri. Sizosavuta kukalamba, ali ndi kukana kutentha kwambiri, ndipo amatha kugwira ntchito mokhazikika kwa nthawi yayitali m'malo ovuta. Izi ndizofunikira kwambiri pakugwira ntchito bwino kwa PCS m'malo osiyanasiyana ovuta.

3. Kukana kwa mphamvu ya ripple

Ma capacitor a filimu ya MDP angagwiritsidwe ntchito kusefa, kuchepetsa kuchuluka kwa ma signal kapena kuchepetsa phokoso la ma signal. Mu PCS, zimathandiza kuchepetsa phokoso la ma frequency ndi ripple zomwe zimapangidwa panthawi yosintha mphamvu, kukonza mphamvu, komanso zingagwiritsidwe ntchito ngati chipangizo cholumikizira kuti zitumize ma signal osiyanasiyana ku ma circuits ogwirizana, potero kuzindikira kuyanjana kwa deta ndi kutumiza ma signal. Kuphatikiza apo, ithanso kugwira ntchito ngati buffer circuit, kuyamwa ndikuletsa kusokoneza kwakanthawi ndi mphamvu yamagetsi mu circuit, kuteteza zigawo zina zamagetsi kuti zisawonongeke.

02 Kusankha kwa capacitor ya filimu komwe kumalimbikitsidwa

Zinthu za pini wamba, ESR yotsika, zinthu za 105℃ 100000H

Chidule cha 03
Ma capacitor a filimu ya YMIN MDPali ndi ubwino wokhala ndi mphamvu zambiri, kukana kwa ripple current, kudalirika kwambiri, komanso moyo wautali. Amathandiza ma PCS converters kusintha AC ndi DC ndikumaliza njira yoyendera mphamvu mbali zonse ziwiri. Nthawi yomweyo, amatha kuchepetsa nsonga ndikudzaza zigwa kuti akonze bwino kugwiritsa ntchito mphamvu, kupewa kupitirira muyeso ndikuwonetsetsa kuti dongosololi ndi lotetezeka. Ndi ofunikira kwambiri pakukweza chitetezo, kukhazikika komanso kugwira ntchito bwino kwa makina osungira mphamvu. Ndi chitukuko chachangu cha makina osungira mphamvu m'munda wa mphamvu zatsopano, mwayi wogwiritsa ntchito ma capacitor amafilimu udzakhala wokulirapo.
