Muchinyakare che inverter ne converter, ma capacitor ebhazi i electrolytic capacitors, asi mune matsva, ma capacitor efirimu anosarudzwa, ndeapi mabhenefiti ema capacitors efirimu kana tichienzanisa nema capacitors e electrolytic?

Parizvino, ma inverter akawanda ari pakati nepakati uye ari kushandisa tambo ari kusarudza ma capacitor efirimu nekuda kwezvikonzero zvinotevera:

(1) Macapacitor efirimu anogona kuwana voltage yakakwira kupfuura macapacitor emagetsi. Voltage yakayerwa yemacapacitor ealuminium electrolytic yakaderera, kusvika ku450 V. Kuti uwane voltage yakakwira, anowanzo fanirwa kushandiswa mu series, uye dambudziko re equalization yevoltage rinofanira kutariswa mu series connection. Kusiyana neizvi, macapacitor efirimu anogona kusvika ku20KV, saka hapana chikonzero chekufunga nezve series connection muma application e medium ne high voltage inverter, uye zvechokwadi, hapana chikonzero chekufunga nezve connection ematambudziko akadai se voltage equalization uye mutengo unoenderana uye vashandi.

(2) Ma capacitor emafirimu ane simba rekudzivirira kupisa kupfuura ma capacitor emagetsi.

(3) Nguva yehupenyu hwecapacitor yefirimu yakareba kupfuura electrolytic capacitor. Kazhinji, nguva yehupenyu hwecapacitor yemagetsi i2,000H, asi nguva yehupenyu hwecapacitor yefirimu yeCRE i100,000H.

(4) ESR idiki zvikuru. ESR yecapacitor yefirimu inowanzova yakaderera zvikuru, kazhinji iri pasi pe1mΩ, uye parasitic inductance yakadererawo zvikuru, makumi mashoma e nH, iyo isingaenzaniswi nearuminiyamu electrolytic capacitors. ESR yakaderera zvikuru inoderedza kushushikana kwevoltage pa switching tube, izvo zvinobatsira pakuvimbika uye kugadzikana kweswitching tube.

(5) Kuramba kwakasimba kweripple current. Kuramba kwakasimba kweripple current yemacapacitor efirimu ane metalized kunogona kuva kagumi kusvika kagumi nekaviri kupfuura ripple current yakayerwa yemacapacitor ealuminium electrolytic ane simba rakafanana. Kuti vawane resistance yakakwira ye current, macapacitor ealuminium electrolytic anowanzo shandisa simba rakakura kuti asvike pazvinodiwa, nepo simba guru richiparadza mari nenzvimbo yekuisa.
