Ho inverter le converter ea setso, li-capacitor tsa bese ke li-capacitor tsa electrolytic, empa ho tse ncha, ho khethoa li-capacitor tsa filimi, melemo ea li-capacitor tsa filimi ke efe ha e bapisoa le li-capacitor tsa electrolytic?

Hona joale, li-inverter tse bohareng le tsa likhoele tse ntseng li eketseha li khetha li-capacitor tsa lifilimi ka mabaka a latelang:

(1) Li-capacitor tsa filimi li ka finyella ho mamella ha motlakase ho feta li-capacitor tsa electrolytic. Motlakase o lekantsoeng oa li-capacitor tsa aluminium electrolytic o tlase, ho fihlela ho 450 V. Ho fumana boemo bo phahameng ba ho mamella ha motlakase, hangata li hloka ho sebelisoa letotong, 'me bothata ba ho lekana ha motlakase bo tlameha ho nahanoa ts'ebetsong ea khokahano ea letoto. Ka lehlakoreng le leng, li-capacitor tsa filimi li ka fihla ho 20KV, kahoo ha ho hlokahale ho nahana ka khokahano ea letoto lits'ebetsong tsa inverter ea motlakase o mahareng le o phahameng, 'me ehlile, ha ho hlokahale ho nahana ka mathata a khokahano a kang ho lekana ha motlakase le litšenyehelo tse tsamaellanang le basebetsi.

(2) Li-capacitor tsa filimi li na le khanyetso e phahameng ea mocheso ho feta li-capacitor tsa electrolytic.

(3) Nako ea bophelo ba capacitor ea filimi e telele ho feta capacitor ea electrolytic. Ka kakaretso, nako ea bophelo ea capacitor ea electrolytic ke 2,000H, empa nako ea bophelo ea capacitor ea filimi ea CRE ke 100,000H.

(4) ESR e nyane haholo. ESR ea capacitor ea filimi hangata e tlase haholo, ka kakaretso e ka tlase ho 1mΩ, 'me ho kenella ha likokoana-hloko le hona ho tlase haholo, ke mashome a' maloa feela a nH, e leng se ke keng sa bapisoa le li-capacitor tsa aluminium electrolytic. ESR e tlase haholo e fokotsa khatello ea motlakase holim'a tube ea switching, e leng molemo bakeng sa ts'epo le botsitso ba tube ea switching.

(5) Khanyetso e matla ea hona joale ea ripple. Khanyetso ea hona joale ea ripple ea li-capacitor tsa filimi tse entsoeng ka tšepe e ka ba makhetlo a leshome ho isa ho a 'maloa a mashome a mabeli a ripple current e lekantsoeng ea li-capacitor tsa aluminium electrolytic tse nang le bokhoni bo tšoanang. E le ho fihlela khanyetso e phahameng ea hona joale, li-capacitor tsa aluminium electrolytic hangata li sebelisa bokhoni bo boholo ho fihlela litlhoko, ha bokhoni bo boholo e le tšenyo e sa hlokahaleng ea litšenyehelo le sebaka sa ho kenya.
