A Polarity Reversing Rectifier (PRR) waa qalab koronto oo DC ah kaas oo bedeli kara polarity-ka wax soo saarkiisa. Tani waxay si gaar ah faa'iido ugu leedahay hababka sida korantada, electrolysis, braking electromagnetic, iyo control motor DC, halkaasoo beddelka jihada hadda loo baahan yahay.
1.Sida ay u shaqeyso
Rectifiers joogta ah waxay u beddelaan AC una beddelaan DC oo leh daraf go'an. PRR-yadu waxay ku dhistaan tan iyagoo isticmaalaya aaladaha awoodda la kontarooli karo-sida thyristors, IGBTs, ama MOSFETs-si loo beddelo socodka hadda socda. Adiga oo hagaajinaya xagasha toogashada ama isku xigxiga beddelka, qalabku wuxuu si habsami leh ama degdeg ah uga rogi karaa wax soo saarka togan una rogi karaa taban.
2.Dhismaha Wareega
Caadi ahaan, PRR waxay isticmaashaa toosiye buundada si buuxda loo kontoroolo:
AC Gelida → Buundada toosiyaha ee la xakameeyey → Shaandheeye → Xamuul
Buundada waxay leedahay afar walxood oo la xakameyn karo. Marka la maareeyo aaladaha ay qabtaan iyo goorta, wax soo saarku wuxuu u kala wareegi karaa:
▪ Polarity togan: hadda waxa uu ka soo qulqulaa terminalka togan ilaa culayska.
▪ Polarity taban: socodka hadda ee jihada ka soo horjeeda.
Heerarka korantada waxa kale oo lagu hagaajin karaa iyada oo la beddelo xagasha kiciya (α), taas oo u oggolaanaysa in si sax ah loo xakameeyo darafnimada iyo baaxadda labadaba.
3.Codsiyada
(1)Electroplating & Electrolysis
Nidaamyada qaarkood waxay u baahan yihiin in hadda uu dib u noqdo xilliyo si loo hagaajiyo tayada dahaarka. PRR-yadu waxay bixiyaan sahayda DC ee la koontarooli karo, laba jiho si loo buuxiyo shuruudahan.
(2) Xakamaynta Baabuurta DC
Waxa loo isticmaalaa hawlgal hore/ka-noqosho iyo braking regeneration, soo celinta tamarta nidaamka.
(3) Braking Electromagnetic
Dib u noqoshada hadda waxa ay suurta gelisaa in si degdeg ah loo joojiyo ama la xakameeyo siidaynta nidaamyada makaanikada.
(4) Shaybaarka & Imtixaanka
PRRs waxay bixiyaan wax soo saarka laba-cirifoodka ee DC, ku habboon cilmi-baarista, tijaabinta, iyo tijaabooyinka u baahan polarity dabacsan.
Rectifiers-ka-noqoshada polarity ayaa si isa soo taraysa muhiim ugu ah warshadaha iyo cilmi-baarista. Waxay isku daraan xakamaynta polarity dabacsan iyo beddelaad tamar hufan, taasoo ka dhigaysa lama huraan codsiyo badan oo koronto oo casri ah. Sida qalabka iyo tignoolajiyada kontoroolka ay u soo hagaagayaan, PRR-yada waxaa laga filayaa inay helaan isticmaal ka sii ballaaran.
