The efficiency(n) of fullwave rectifier is defined as: n=DC output Power/AC input power But Power=V*I n=Vdc*Idc/Vrms*Irms But Vdc=2Vm/pi,Idc=2Im/pi ,Irms=Im/root(2),Vrms=Vm/root(2) (Im:Peak Curent) n=(4Vm*Im/pi^2)/(Vm*Im/2)=8/pi^2=0.812=81.2%. So efficiency of full wave rectifier is 81.2%
Working the rectifier
centre tap transform convert ac into full wave rectifeir dc .It needs only two diodes but efficiency is less.
Rectifier is used to convert alternating current to direct current.
It is not a good efficiency engine.
Efficiency is double in case of full wave rectifier.
The conversion efficiency n of a rectifier ckt is generally defined as Na= dc power delivered to the load/ ac power input to the rectifier ckt. Or n = Pdc/Pac

1. Efficiency of full wave rectifier is better than other rectifiers i.e, Efficiency()=81.2%. 2.It's Peak Inverse voltage (P I V)=2Vm.

Most computer power supplies contain both. The transformers are usually toroidal transformers for high efficiency and compactness.
It is defined as dc power delivered to the load to the ac input power from secondary transformer
Working the rectifier
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
Personal efficiency is the result of good time-management combined with good self-management
Bridge Rectifier DiodesIn a "bridge" rectifier there is 4 diodes In a "full wave" there are 2 diodes.In a "half wave" rectifier there is 1 diode.
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
