A: Most devices and IC do not or cannot work properly with AC applied therefore the AC is rectified to DC. Full wave rectification Will give more power.
The bridge doesn't require a center-tapped transformer secondary, so has
available the voltage of the full secondary winding, rather than half of it.

Half wave rectifier makes the the sinusoidal wave uni-direction only in one half cycle and leave the other but in full wave rectifier both the cycles are made uni-directional.
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
You use a half-wave rectifier where the system design does not require a full-wave approach. Half wave rectifier output is used for running ac motors.
The output degrades to a half-wave rectifier.
The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.
Half wave rectifier makes the the sinusoidal wave uni-direction only in one half cycle and leave the other but in full wave rectifier both the cycles are made uni-directional.
Efficiency is double in case of full wave rectifier.
"What is the functioning procedure of full wave rectifier by using SCRs?" "What is the functioning procedure of full wave rectifier by using SCRs?"
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
in full wave bridge rectifier, the input and out put voltages are same but in case of two diode rectifier the input and output voltages can be different as per requirement a there is a transformer in the circuit. The former is lighter and the later is heavier.
full wave rectifier, because in half wave rectifier only one p-n junction diode Ans 2. In full wave rectifier both negative & positive cycles are rectified , but , in half wave rectifier only the positive or the negative cycle is rectified . That's why full wave rectifier provides more power .
What are the advantages and disadvantages of wave energy
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
A half wave rectifier is not as effective as a full wave rectifier. With a 1/2 wave, you are throwing away one hump of the sine wave...either positive or negative portion. With a full wave rectifier you get both humps...either positive or negative. The resultant effective voltage is much greater with a full wave rectifier, because there is very little time when the voltage is zero. The half wave is zero for 1/2 of the cycle.
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.
The purpose of a bridge rectifier is to basically turn AC into DC. In a half wave rectifier you just eliminate the negative part of sine wave so you have positive cycle and then zero volts for 1/2 a cycle. In a full wave you flip the negative to positive so you have continually repeating positive halfs of the sine wave. So, it is easier to filter the full wave into DC with a capacitor and you get more average power. The down side is the bridge is slightly more complex.
