DC Power Supply 4

Full wave rectifier
 

Center-tapped (CT) rectifier requires center-tap transformer. Full Bridge (FB) does not.



CT: 2 diodes

FB: 4 diodes. Hence, CT experienced only one diode volt-drop per half-cycle



Conduction losses for CT is half.



Diodes ratings for CT is twice than FB
