Imagine a sine wave. It is a wave that has both a positive and negative component that varies continuously over time. For most power applications in the USA this rate is 60 hertz or 60 cycles per second.
A half-wave rectifier just removes the negative part of the wave so now you have a positive hump for a period of time and then zero for the same period and then positive and so forth.
For a full-wave you just flip the negative hump positive so you have positive hump followed by positive hump and on and on.
A half-wave rectifier allows only one half cycle to pass. In some cases this may well be the positive excursion, as stated above, but it can be connected the other way round so that only the negative excursion passes.
It depends, of course, on whether you want positive or a negative d.c. (relative to your circuit/system common).

What is the functioning procedure of full wave rectifier by using SCRs?
"What is the functioning procedure of full wave rectifier by using SCRs?" "What is the functioning procedure of full wave rectifier by using SCRs?"
Why full wave rectifier is preffered over half wave rectifier?
Efficiency is double in case of full wave rectifier.
What is the frequency of ripple components in the output of capacitor filter?
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.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
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.
Which provide more power and why full wave or half wave rectification?
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 is the advantages of halt wave rectifier over full wave rectifier?
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.
What is ripple factor of the Full-wave rectifier?
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
Conclusions of full-wave rectifier?
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.
How many diodes in a bridge rectifier?
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.
How do you connect cathode ray oscilloscope to full wave rectifier?
To connect a cathode ray oscilloscope (CRO) to a full-wave rectifier, first, ensure the rectifier circuit is powered and functioning properly. Connect the oscilloscope probes across the output terminals of the rectifier; the positive probe should connect to the positive output, and the ground clip to the common ground. Set the oscilloscope to an appropriate voltage scale and time base to visualize the rectified waveform. Finally, observe the display, which should show the full-wave rectified signal.
How many diodes are used to make a half wave rectifier?
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.
What happens to the output when one of the diode becomes open in full wave bridge rectifier?
The output degrades to a half-wave rectifier.
