Ku-inverter kanye ne-converter yendabuko, ama-capacitor ebhasi angama-capacitor e-electrolytic, kodwa kwalawa amasha, kukhethwa ama-capacitor efilimu, yiziphi izinzuzo zama-capacitor efilimu uma kuqhathaniswa nama-capacitor e-electrolytic?

Njengamanje, ama-inverter amaningi aphakathi nendawo kanye nezintambo akhetha ama-capacitor efilimu ngezizathu ezilandelayo:

(1) Ama-capacitor efilimu angafinyelela ukumelana okuphezulu kwamandla kagesi kune-capacitor ye-electrolytic. I-voltage elinganisiwe yama-capacitor e-aluminium electrolytic iphansi, ifinyelela ku-450 V. Ukuze uthole izinga eliphakeme lokumelana namandla kagesi, ngokuvamile kudingeka asetshenziswe ochungechungeni, futhi inkinga yokulingana kwamandla kagesi kumele icatshangelwe enkambisweni yokuxhumeka kochungechunge. Ngokuphambene nalokho, ama-capacitor efilimu angafinyelela ku-20KV, ngakho-ke asikho isidingo sokucabangela ukuxhumana kochungechunge ezicelweni ze-inverter ze-voltage ephakathi nephezulu, futhi-ke, asikho isidingo sokucabangela izinkinga zokuxhumeka ezifana nokulingana kwamandla kagesi kanye nezindleko ezihambisanayo kanye namandla abasebenzi.

(2) Ama-capacitor efilimu anokumelana nokushisa okuphezulu kunama-capacitor e-electrolytic.

(3) Isikhathi sokuphila se-capacitor yefilimu side kune-capacitor ye-electrolytic. Ngokuvamile, isikhathi sokuphila se-capacitor ye-electrolytic singu-2,000H, kodwa isikhathi sokuphila se-capacitor yefilimu ye-CRE singu-100,000H.

(4) I-ESR incane kakhulu. I-ESR ye-capacitor yefilimu ivame ukuba phansi kakhulu, ngokuvamile ingaphansi kwe-1mΩ, kanti i-inductance ye-parasitic nayo iphansi kakhulu, ingamashumi ambalwa kuphela e-nH, okungenakuqhathaniswa nama-capacitor e-aluminium electrolytic. I-ESR ephansi kakhulu inciphisa ukucindezeleka kwe-voltage ku-switching tube, okuzuzisa ukuthembeka nokuzinza kwe-switching tube.

(5) Ukumelana okunamandla kwamanje we-ripple. Ukumelana kwamanje we-ripple kwama-capacitor efilimu ensimbi kungaba izikhathi eziyishumi kuya kweziningana zamanje we-ripple current olinganiselwe wama-capacitor e-aluminium electrolytic anamandla afanayo. Ukuze kufezwe ukumelana kwamanje okuphezulu, ama-capacitor e-aluminium electrolytic avame ukusebenzisa amandla amakhulu ukuhlangabezana nezidingo, kuyilapho amandla amakhulu kuwukuchitha izindleko kanye nendawo yokufaka okungadingekile.
