Muri inverter na converter bisanzwe, capacitors za bisi ni capacitors za electrolytic, ariko mu nshya, capacitors za filime ziratoranywa, ni izihe nyungu za capacitors za filime ugereranyije na capacitors za electrolytic?

Muri iki gihe, inverters nyinshi zikoresha ibyuma binini kandi bikoresha imigozi zihitamo capacitors za filime kubera impamvu zikurikira:

(1) Capacitors za filime zishobora kugira imbaraga zo kwihanganira amashanyarazi menshi kurusha capacitors za electrolytic. Voltage ihanitse ya capacitors za aluminium electrolytic ni ntoya, kugeza kuri 450 V. Kugira ngo zibone imbaraga zo kwihanganira amashanyarazi menshi, akenshi zigomba gukoreshwa mu buryo bukurikiranye, kandi ikibazo cyo kuringaniza amashanyarazi kigomba gusuzumwa mu gihe cyo guhuza amashanyarazi. Mu buryo bunyuranye, capacitors za filime zishobora kugera kuri 20KV, bityo nta mpamvu yo gusuzuma uburyo bwo guhuza amashanyarazi mu buryo buciriritse n'ubunini bw'amashanyarazi, kandi birumvikana ko nta mpamvu yo gusuzuma ibibazo byo guhuza amashanyarazi nko kuringaniza amashanyarazi n'igiciro gihuye n'icyo hamwe n'abakozi.

(2) Capacitors za firime zifite ubushyuhe bwinshi kurusha capacitors za electrolytic.

(3) Igihe cy'ubuzima bwa capacitor ya filime ni kirekire kurusha capacitor ya electrolytic. Muri rusange, igihe cy'ubuzima bwa capacitor ya electrolytic ni 2.000H, ariko igihe cy'ubuzima bwa capacitor ya filime ya CRE ni 100.000H.

(4) ESR ni nto cyane. ESR ya capacitor ya filime ubusanzwe iba iri hasi cyane, muri rusange iri munsi ya 1mΩ, kandi inductance ya parasite nayo iba iri hasi cyane, ni mirongo mike ya nH, ikaba idashobora kugereranywa na capacitors za electrolytic za aluminiyumu. ESR iri hasi cyane igabanya imbaraga z'amashanyarazi kuri tube ihinduranya, ibi bikaba ingirakamaro ku kwizerwa no kudahungabana k'umuyoboro uhinduranya.

(5) Ubudahangarwa bukomeye bw'umuyoboro w'amashanyarazi. Ubudahangarwa bw'umuyoboro w'amashanyarazi wa capacitors za filime zikozwe mu byuma bushobora kuba inshuro icumi kugeza kuri mirongo ibiri z'umuyoboro w'amashanyarazi wa capacitors za aluminium electrolytic zifite ubushobozi bumwe. Kugira ngo zigere ku budahangarwa bwinshi bw'umuyoboro w'amashanyarazi, capacitors za aluminium electrolytic zikoresha ubushobozi bwinshi kugira ngo zihuze n'ibikenewe, mu gihe ubushobozi bwinshi ari ugupfusha ubusa ikiguzi n'umwanya wo gushyiraho.
