Farqiga Muhiimka ah iyo Codsiyada
Rectifiers waa qaybo lagama maarmaan ah oo ku jira wareegyada kala duwan ee elektiroonigga ah iyo nidaamyada korontada. Waxay beddelka hadda (AC) u beddelaan hadda toos ah (DC), iyagoo siinaya awoodda lagama maarmaanka u ah aalado iyo codsiyo badan. Waxaa ka mid ah noocyada kala duwan ee toosiyeyaasha, hagaajinta garaaca wadnaha iyo toosiyeyaasha polarity-ga ayaa caan ku ah sifooyinkooda iyo codsiyadooda gaarka ah. Maqaalkani waxa uu si qoto dheer u eegayaa farqiga u dhexeeya labadan nooc ee toosiyeyaasha, mabaadi'dooda shaqo, faa'iidooyinka, khasaarooyinka, iyo codsiyada.
Rectifiers garaaca wadnaha
Rectifiers-ka garaaca wadnaha, sidoo kale loo yaqaan rectifiers garaaca ama toosiyeyaasha la kontaroolo, waa aaladaha u beddela AC una beddela DC iyaga oo isticmaalaya aaladaha semiconductor-ka la kantaroolay sida thyristors ama toosiyeyaasha silicon-controlled (SCRs). Dib-u-habeeyayaashan ayaa inta badan loo adeegsadaa codsiyada u baahan in si sax ah loo xakameeyo tamarta wax soo saarka iyo kuwa hadda socda.
Mabda'a Shaqada
Hawsha hagaajinta garaaca wadnaha waxa ay ku lug leedahay xakamaynta xagasha wejiga ee danab AC. Iyadoo la hagaajinayo xagasha kicinta ee SCR-yada, korantada DC ee wax soo saarka ayaa la habeyn karaa. Marka SCR-gu kiciyo, waxay u ogolaataa in hadda uu soo gudbo ilaa wareegga AC uu gaaro eber, markaas oo SCR-gu uu damiyo. Habkani waxa uu ku soo noqnoqda wareegga badhkii kasta ee gelinta AC, isaga oo soo saaraya wax soo saarka DC ee garaaca.

Dib-u-habaynta Polarity Reverse
Dib-u-habeeyayaasha dib-u-dejinta, oo sidoo kale loo yaqaanno toosiyeyaasha ilaalinta polarity-ga ama dib-u-habeeyayaasha ilaalinta korantada, ayaa loogu talagalay in ay ka ilaaliyaan wareegyada waxyeellada ay keento isku-xirnada polarity-ka ee khaldan. Waxay hubiyaan in wareeggu si sax ah u shaqeeyo xitaa haddii korontadu rogtay.
Mabda'a Shaqada
Qaybta aasaasiga ah ee dib-u-habaynta polarity waa diode ama isku-darka diodka. Marka si taxane ah loogu xiro koronto, diode-ku wuxuu u oggolaanayaa hadda inuu u socdo jihada saxda ah oo keliya. Haddii polarity-ka la rogo, diode-ku wuxuu xannibaa hadda, isagoo ka hortagaya waxyeellada wareegga.
Naqshado aad u horumarsan, MOSFETs (birta-oxide-semiconductor field-affect transistor) ayaa loo isticmaalaa in lagu bixiyo hoos u dhaca danab hore iyo hufnaan sare marka loo eego diodes. Dib-u-habeeyayaasha MOSFET-ku-saleysan waxay si toos ah ula qabsanayaan polarity-ka saxda ah waxayna xaqiijiyaan shaqada habboon ee wareegga.
