Kipengele
1. Mfuko wa kesi ya chuma, Imefungwa na resin;
2. Maombi ya mfumo wa nguvu ya juu ya voltage;
3. Mzunguko wa nguvu ya juu;
4. Upinzani wa voltage ya juu, na uponyaji binafsi;
5. Mtiririko wa juu wa sasa, dv ya juu / dt kuhimili uwezo.
Kazi
Katika kichujio cha pato cha usambazaji wa umeme wa DC, kazi ya capacitor ni kudumisha thamani ya DC isiyobadilika kwa kuondoa ripple ya nguvu nyingi iwezekanavyo.
Vigeuzi vyote vya AC-DC, iwe ni vifaa vya mstari au vina aina fulani ya kipengee cha kubadilisha kwao, vinahitaji utaratibu wa kuchukua nguvu tofauti kwenye upande wa AC na kutoa nguvu ya mara kwa mara kwenye upande wa DC.
