Korontada 12v waa in la isticmaalo aaladaha wareejinta elektiroonigga ah (sida transistor-ka, transistor-ka saamaynta goobta, thyristors, iwm.) modulation waxaa lagu sameeyaa danab gelinta si loo xaqiijiyo beddelka korantada DC / AC, DC / DC, iyo sidoo kale danab wax soo saarka la hagaajin karo iyo nidaamka danab toos ah.

Korontada 12v ee beddesha guud ahaan waxa ay leedahay saddex hab oo shaqo: soo noqnoqoshada, balaadhka garaaca garaaca qaab go'an, soo noqnoqoshada go'an, qaab ballarka garaaca wadnaha, inta jeer, garaaca width variable mode.Qaabkii hore ee shaqada ayaa inta badan loo isticmaalaa sahayda korantada ee DC/AC, ama beddelka korantada DC/DC;Labada hab ee ugu dambeeya ee shaqada ayaa inta badan loo adeegsadaa beddelidda sahayda korantada ee nidaamsan.Intaa waxaa dheer, korantada wax soo saarka ee sahayda wareejinta waxay sidoo kale leedahay saddex qaab oo shaqo: qaabka korantada wax soo saarka tooska ah, celceliska qaabka wax soo saarka, iyo qaabka wax soo saarka xajmiga.Sidoo kale, qaabkii hore ee shaqada ayaa inta badan loo isticmaalaa sahayda korantada ee DC/AC, ama beddelka korantada DC/DC;Labada hab ee ugu dambeeya ee shaqada ayaa inta badan loo adeegsadaa beddelidda sahayda korantada ee nidaamsan.

Marka la eego habka ay aaladaha beddelidda ugu xidhan yihiin wareegga, sahayda beddelka ee sida weyn loo isticmaalo waxa loo qaybin karaa qiyaas ahaan saddex qaybood: Korontada beddelka ee taxanaha ah, sahayda beddelka korontadda oo isbar-bar socda, iyo sahayda beddelka beddelka.Waxaa ka mid ah, korontada beddelka beddelka ah (oo hadda loo yaqaanno koronto beddelka beddelka) ayaa loo sii kala qaybin karaa: nooca riixitaanka, nooca buundada badhkeed, nooca buundada buuxa, iwm.;marka loo eego kicinta qalabka wax-soo-saarka iyo wejiga korantada wax-soo-saarka, waxaa loo sii kala qaybin karaa: nooca xamaasadda hore, duulista, hal-excitation iyo dual-excitation, iwm.;haddii loo qaybiyo isticmaalka, waxa loo qaybin karaa noocyo badan.

Hoos waxaan si kooban u soo bandhigi doonaa mabaadi'da shaqada ee saddexda sahayda korantada beddelka ah ee aasaasiga ah, sida taxane, barbaryaal, iyo transformer.Noocyada kale ee sahayda korantada wareejinta ayaa sidoo kale si faahfaahsan loo falanqeyn doonaa tallaabo tallaabo.
