Polarity Reversing Rectifier (PRR) ni igikoresho gitanga amashanyarazi cya DC gishobora guhindura polarity y'umusaruro wacyo. Ibi bituma kigira akamaro cyane mu bikorwa nko gukoresha electroplating, electrolysis, feri ya electromagnetic, na DC moteri control, aho guhindura icyerekezo cy'amashanyarazi ari ngombwa.
1. Uko Bikora
Imashini zisanzwe zihindura AC muri DC zifite polarity idahinduka. PRRs zubaka ibi zikoresha ibikoresho by'amashanyarazi bishobora kugenzurwa—nk'ibinyabiziga bya thyristors, IGBTs, cyangwa MOSFETs—kugira ngo zihindure inzira y'amashanyarazi. Mu guhindura inguni yo kurasa cyangwa urukurikirane rw'ihindagurika ry'amashanyarazi, igikoresho gishobora guhindura neza cyangwa vuba umusaruro uva kuri positive ujya kuri negative.
2. Imiterere y'uruziga
Ubusanzwe, PRR ikoresha icyuma gikosora ibiraro gicungwa neza:
Injira rya AC → Ikiraro cyo Gusubiza Amajwi Gicungwa → Akayunguruzo → Gushyiramo
Ikiraro gifite ibintu bine bishobora kugenzurwa. Mu gucunga ibikoresho bikoresha n'igihe bikorera, umusaruro ushobora guhinduka hagati ya:
▪ Polarité nziza: umuyoboro w'amashanyarazi uva kuri terminal nziza ujya ku mutwaro.
▪ Polarite mbi: umugezi unyura mu cyerekezo gitandukanye.
Urugero rw'amashanyarazi rushobora kandi guhindurwa hakoreshejwe guhindura inguni y'imashini (α), bigatuma habaho kugenzura neza polarity n'ubunini bw'amashanyarazi.
3. Porogaramu
(1) Gutunganya amashanyarazi n'amashanyarazi
Hari inzira zimwe na zimwe zikenera ko umuriro usubira inyuma buri gihe kugira ngo wongere ireme ry'imvange. PRRs zitanga DC ishobora kugenzurwa kandi igana impande zombi kugira ngo ihuze n'ibi bisabwa.
(2) Igenzura rya moteri ya DC
Ikoreshwa mu gukora imbere/inyuma no kugabanya feri, igasubiza ingufu muri sisitemu.
(3) Gufunga amashanyarazi
Gusubiza inyuma umuriro bituma sisitemu za mekanike zirekurwa vuba cyangwa zigacungwa.
(4) Laboratwari n'ibizamini
PRRs zitanga umusaruro wa bipolar DC ushobora gutegurwa, ukaba mwiza cyane mu bushakashatsi, ibizamini, n'igerageza risaba polarity yoroshye.
Imashini zihindura imiterere y’amashanyarazi zigenda zirushaho kuba ingenzi mu nganda no mu bushakashatsi. Zihuza uburyo bwo kugenzura imiterere y’amashanyarazi buhindagurika hamwe no guhindura ingufu neza, bigatuma ziba ingenzi mu bikorwa byinshi bigezweho by’ikoranabuhanga. Uko ikoranabuhanga ry’ibikoresho n’igenzura rigenda ritera imbere, byitezwe ko PRR zikoreshwa cyane.
