Mu modoka nshya zikoresha ingufu, capacitors ni zo ngingo z'ingenzi zigena igihe cyo gukoresha frequency ihindagurika mu kugenzura ingufu, gucunga ingufu, inverter y'amashanyarazi na sisitemu zo guhindura DC-AC.Capacitor ya DC-LINKIhujwe na bateri yo kubika ingufu hamwe n'icyuma gihindura inverter kugira ngo gikurure umuvuduko mwinshi w'amashanyarazi uva ku mpera ya DC-Link, bishobora kubuza ingufu nyinshi z'amashanyarazi gukorwa kuri impedance ya DC-Link, bityo ihindagurika ry'amashanyarazi ku mpera ya inverter rikaba riri mu rugero rukwiye; Muri icyo gihe, ishobora kubuza inverter kugira ingaruka ku kwiyongera kwa voltage no kwiyongera kwa voltage ku gice cya DC-Link.

Ibisobanuro by'ingenzi bya tekiniki bya capacitors za DC-Link ni ubushobozi bwo gukora, imbaraga zo kwihanganira voltage n'ubushyuhe bw'imikorere. Uretse ibi bimenyetso bitatu by'ingenzi, ikindi kimenyetso cy'ingenzi cya tekiniki ni ubushobozi bwo guhangana n'uruhererekane rw'ibikoresho (ESR) bya capacitors. Muri capacitors za DC-Link, ESR igaragaza igihombo cya capacitors ubwayo. Uko ESR iba nto, igihombo kiba gito, umuvuduko w'amashanyarazi uba munini, ubushyuhe bwa capacitors buba buke, kandi imikorere iba myiza.

Capacitors za filime zikora neza za CRE zikoreshwa cyane mu modoka nshya zikoresha ingufu, ingufu zikomoka ku muyaga, ubwikorezi bwa gari ya moshi n'izindi nganda. Muri zo,DKMJ-AP Capacitors zikoreshwa by'umwihariko muri sisitemu nshya y'amashanyarazi ikoresha frequency ihindagurika, ifite imbaraga nyinshi zo kurwanya voltage, ubushobozi bunini, urwego rugari rw'akazi na ESR iri hasi cyane.
