Ubuharike buhindura ikosora

Polarity Reversing Rectifier (PRR) nigikoresho cya DC gitanga amashanyarazi gishobora guhindura polarite yibisohoka. Ibi bituma bigira akamaro cyane mubikorwa nka electroplating, electrolysis, feri ya electromagnetic feri, hamwe na moteri ya DC, aho guhindura icyerekezo kigezweho.

1.Uburyo Bikora
Ikosora risanzwe rihindura AC kuri DC hamwe na polarite ihamye. PRRs yubaka kuri ibi ukoresheje ibikoresho byingufu zishobora kugenzurwa-nka thyristors, IGBTs, cyangwa MOSFETs-kugirango uhindure imigendekere yubu. Muguhindura imirishyo cyangwa guhinduranya urukurikirane, igikoresho kirashobora gukora neza cyangwa byihuse gusohora ibisohoka bivuye mubyiza bikagenda nabi.

2.Umuzenguruko
Mubisanzwe, PRR ikoresha igenzura ryuzuye ryikiraro:
AC Iyinjiza → Igenzurwa Ikosora Ikiraro → Akayunguruzo → Umutwaro
Ikiraro gifite ibintu bine bigenzurwa. Mugucunga ibikoresho bitwara nigihe, ibisohoka birashobora guhinduka hagati:
Po polarite nziza: ikigezweho kiva kumurongo mwiza ujya kumuzigo.
Ar Polarite mbi: imigendekere yimbere muburyo bunyuranye.
Urwego rwa voltage narwo rushobora guhindurwa muguhindura inguni (α), bigatuma igenzura neza ryuburinganire nubunini.

3.Gusaba
(1) Amashanyarazi & Electrolysis
Inzira zimwe zikenera ikigezweho kugirango zihinduke mugihe kugirango tunoze ubuziranenge. PRRs itanga kugenzurwa, ibyerekezo byombi DC kugirango byuzuze iki gisabwa.
(2) Igenzura rya moteri ya DC
Byakoreshejwe imbere / gusubiza inyuma no gufata feri nshya, gusubiza ingufu muri sisitemu.
(3) Gufata amashanyarazi
Guhindura ibyubu bituma feri yihuta cyangwa igenzurwa kurekura sisitemu ya mashini.
(4) Laboratoire & Kwipimisha
PRRs itanga progaramu ya bipolar DC isohoka, nibyiza kubushakashatsi, kugerageza, nubushakashatsi busaba polarite yoroheje.

Ikosora rya polarite iragenda iba ingirakamaro mubikorwa n'inganda. Bahuza uburyo bworoshye bwo kugenzura no guhinduranya ingufu neza, bigatuma biba ngombwa kubintu byinshi bigezweho bya elegitoroniki. Mugihe ibikoresho no kugenzura ikoranabuhanga bigenda bitera imbere, PRRs ziteganijwe kubona nogukoresha byinshi.
