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

Hajoale, li-inverters tse ntseng li eketseha le tse bohareng li ntse li khetha li-capacitor tsa lifilimi ka mabaka a latelang:

(1) Li-capacitor tsa lifilimi li ka khona ho mamella matla a phahameng ho feta li-electrolytic capacitors.The gagamalo rated ea aluminium electrolytic capacitors e tlaase, ho fihlela ho 450 V. Ho fumana phahameng gagamalo mamella boemo ba, hangata ba lokela ho sebelisoa ka letoto la lihlooho tse, 'me bothata ba gagamalo equalization lokela ho nkoa ka tshebetso ya letoto kgokelo ya.Ka lehlakoreng le leng, li-capacitor tsa filimi li ka fihla ho 20KV, kahoo ha ho hlokahale hore u nahane ka letoto la khokahanyo ho lisebelisoa tsa motlakase oa motlakase o mahareng le o phahameng, 'me ha e le hantle, ha ho hlokahale hore u nahane ka mathata a khokahano a kang ho lekanngoa ha motlakase le litšenyehelo tse lumellanang le tsona. basebetsi.

(2) Li-capacitor tsa lifilimi li na le mocheso o phahameng ho feta li-electrolytic capacitors.

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

(4) ESR e nyane haholo.ESR ea filimi ea capacitor hangata e tlase haholo, ka kakaretso e ka tlase ho 1mΩ, 'me inductance ea parasitic e boetse e tlaase haholo, ke mashome a seng makae feela a nH, e ke keng ea bapisoa le aluminium electrolytic capacitors.ESR e tlase haholo e fokotsa khatello ea motlakase ho switching tube, e leng molemo ho ts'epahalo le botsitso ba tube ea switching.

5E le ho finyella khanyetso e phahameng ea hona joale, aluminium electrolytic capacitors hangata e sebelisa matla a maholo ho finyella litlhoko, athe matla a maholo ke tšenyo e sa hlokahaleng ea litšenyehelo le sebaka sa ho kenya.
