Ezimotweni ezintsha zikagesi zamandla, ama-capacitor ayizingxenye ezibalulekile zokunquma impilo ye-variable frequency drive ekulawuleni amandla, ukuphathwa kwamandla, i-inverter yamandla kanye nezinhlelo zokuguqula i-DC-AC.II-DC-LINK capacitorixhunywe nebhethri eligcina amandla kanye neyunithi ye-inverter ukuze imunce ukushaya kwe-pulse kwamanje kwe-inverter kusukela ekugcineni kwe-DC-Link, okungavimbela amandla kagesi aphezulu ukuthi akhiqizwe ekubambeni kwe-DC-Link, ukuze i-voltage ukushintshashintsha ekupheleni kwe-inverter kungaphakathi kwebanga elamukelekayo;Ngesikhathi esifanayo, ingakwazi ukuvimbela inverter ukuthi ingathinteki i-voltage overshoot kanye ne-over-voltage yesikhashana esikhumulweni se-DC-Link.

Ukucaciswa okuyinhloko kobuchwepheshe be-DC-Link capacitor yi-capacitance, ukumelana ne-voltage kanye nobubanzi bokushisa obusebenzayo.Ngaphezu kwalezi zinkomba ezintathu eziyinhloko, enye inkomba yezobuchwepheshe ebalulekile ukumelana nochungechunge olulinganayo (ESR) lwe-capacitor.Ku-DC-Link capacitor, i-ESR imelela ukulahlekelwa kwe-capacitor ngokwayo.I-ESR ephansi, ukulahlekelwa okuncane, ukukhishwa kwamanje okukhulu, ukushisa okuphansi kwe-capacitor, nokusebenza kangcono.

Ama-capacitor amafilimu e-CRE asebenza kakhulu asetshenziswa kakhulu ezimotweni zamandla amasha, ukukhiqiza amandla omoya, ezokuthutha ngojantshi nakwezinye izimboni.Phakathi kwazo,I-DKMJ-AP ama-capacitor asetshenziswa ngokukhethekile ohlelweni olusha lwemoto kagesi oluguquguqukayo oluguquguqukayo, olunamandla okumelana nomthamo omkhulu, umthamo omkhulu, ububanzi bokusebenza kanye ne-ultra-low ESR.
