The full wave rectifier is a means of converting alternating current (ac) into direct current (dc). It is done with either the use of 2 diodes coming off a center tapped transformer, or by using a bridge rectifier, which conists of 4 diodes ganged together in a certain configuration. As it's name implies, it converts both the positive going and the negative going parts of the sign wave into useable dc, and therefore is more efficient than a half wave rectifier, which only converts 1/2 of the complete sign wave into useable dc.

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.


Is there any application where center tap rectifier is preferred over bridge rectifier?

For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.


What has the greater current in the diodes bridge rectifier circuit or full-wave rectifier circuit?

They both have the same current.


What is the main difference between a bridge rectifier and a full wave rectifier?

Both the bridge rectifier and the full-wave rectifier achieve the same thing. They rectify the AC input on both opposing phases so as to minimize ripple time and voltage. The difference is that a bridge rectifier consists of four diodes arranged in a bridge, so the input needs to only be single phase AC, while a full wave rectifier consists of two diodes, but needs a split phase AC source, such as provided by a center tapped transformer winding. Also, the bridge rectifier presents two junction drops in the output, because there are always two diodes in series, while the full-wave rectifier presents only one junction drop in the output, because there is only one. It is a trade-off.

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 .
