Muchinyakare inverter uye converter, bhazi capacitors ari electrolytic capacitors, asi mune itsva, firimu capacitors anosarudzwa, ndezvipi zvakanakira mafirimu capacitors zvichienzaniswa ne electrolytic capacitors?

Parizvino, yakawanda uye yakawanda yepakati uye tambo inverters vari kusarudza mafirimu capacitors nekuda kwezvikonzero zvinotevera:

(1) Mafirimu capacitors anogona kuwana yakakwira voltage inomira kupfuura electrolytic capacitors.Iyo yakatemerwa voltage yealuminium electrolytic capacitors yakaderera, inosvika 450 V. Kuti uwane yakakwirira voltage inomira pamwero, ivo vanowanzoda kushandiswa munhevedzano, uye dambudziko rekuenzana kwevoltage rinofanira kutariswa mukuita kwekuteedzera kubatana.Kusiyana neizvi, mafirimu capacitors anogona kusvika ku20KV, saka hapana chikonzero chekufunga nezve kubatanidza kubatanidza mune yepakati uye yakakwira voltage inverter application, uye chokwadi, hapana chikonzero chekufunga nezve matambudziko ekubatanidza akadai sekuenzana kwevoltage uye mutengo unoenderana. manpower.

(2) Firimu capacitors ane yakakwirira tembiricha kuramba kupfuura electrolytic capacitors.

(3) Nguva yehupenyu yefirimu capacitor yakareba kudarika electrolytic capacitor.Kazhinji, hupenyu hwe electrolytic capacitor i2,000H, asi hupenyu hweCRE film capacitor i100,000H.

(4) ESR idiki zvakanyanya.Iyo ESR yefirimu capacitor inowanzove yakaderera zvakanyanya, kazhinji pazasi 1mΩ, uye iyo parasitic inductance zvakare yakaderera kwazvo, mashoma makumi mashoma nH, iyo isingaenzaniswi nealuminium electrolytic capacitors.Iyo yakanyanya kuderera ESR inoderedza kushushikana kwemagetsi pane switching chubhu, iyo inobatsira kuvimbika uye kugadzikana kweiyo switching chubhu.

(5) Yakasimba ripple current resistance.The ripple current resistance ye metalized film capacitors inogona kuva gumi kusvika kune gumi nembiri nguva dze rated ripple current yealuminium electrolytic capacitors of the same capacity.Kuti uwane yakakwira yazvino kuramba, aluminium electrolytic capacitor inowanzo shandisa yakakura kugona kuzadzisa zvinodiwa, nepo yakakura kurira kuri kutambisa kusingakoshi kwemutengo uye nzvimbo yekuisa.
