Kwizithuthi zombane zamandla amatsha, ii-capacitors zizinto eziphambili zokumisela ubomi be-variable frequency drive kulawulo lwamandla, ulawulo lwamandla, inverter yamandla kunye ne-DC-AC yokuguqula iinkqubo.II-DC-LINK capacitoridityaniswe nebhetri yokugcina amandla kunye neyunithi ye-inverter ukufunxa i-pulse yangoku ye-inverter ukusuka kwi-DC-Link ekupheleni, enokuthintela umbane ophezulu we-pulse ukuveliswa kwi-impedance ye-DC-Link, ukuze umbane. ukuguquguquka kwisiphelo se-inverter kuluhlu olwamkelekileyo;Kwangaxeshanye, inokuthintela i-inverter ukuba ingachatshazelwa yi-voltage overshoot kunye ne-transient over-voltage kwi-terminal ye-DC-Link.

Iimpawu eziphambili zobugcisa ze-DC-Link capacitors zi-capacitance, ukumelana nombane kunye nomgangatho wokushisa osebenzayo.Ukongeza kwezi zikhombisi zithathu eziphambili, esinye isalathisi esibalulekileyo sobuchwephesha kukuxhathisa uchungechunge olulinganayo (ESR) ye-capacitor.Kwi-DC-Link capacitor, i-ESR imele ukulahlekelwa kwe-capacitor ngokwayo.I-ESR ephantsi, ilahleko encinci, inkulu imveliso yangoku, iyancipha ukushisa kwe-capacitor, kunye nokusebenza ngcono.

I-CRE high-performance film capacitors isetyenziswa ngokubanzi kwizithuthi zamandla amatsha, ukuveliswa kwamandla omoya, ukuhamba ngololiwe kunye namanye amashishini.Phakathi kwabo,I-DKMJ-AP ii-capacitors zisetyenziswa ngokukodwa kwinkqubo entsha yombane yombane eguquguqukayo, enokumelana nombane ophezulu, umthamo omkhulu, uluhlu olubanzi lokusebenza kunye ne-ultra-low ESR.
