introduction A rectifier is an electrical device that converts alternating
current (AC), which periodically reverses direction,
to direct current (DC), which is in only one direction, a
process known as rectification.

In half wave rectification, either the positive or
negative half of the AC wave is passed, while the
other half is blocked.
Because only one half of the input waveform reaches
the output, it is very inefficient if used for power
transfer.

Output dc voltage calculation
The output DC voltage of a half wave rectifier can
be calculated with the following two ideal equations
![Page 9: rectifiers and all about rectifier](https://reader036.fdocuments.in/reader036/viewer/2022062522/5884290b1a28ab485c8b6e4d/html5/thumbnails/9.jpg)
Full wave rectification In a circuit with a non - center
tapped transformer, four diodes are required
instead of the one needed for half-wave
rectification.
For single-phase AC, if the transformer is
center-tapped, then two diodes back-to-back
(i.e. anodes-to-anode or cathode-to-cathode)
can form a full-wave rectifier.

formula
The average and root-mean-square output
voltages of an ideal single phase full wave
rectifier can be calculated as:

Bridge rectifier
A bridge rectifier makes use of four diodes
in a bridge arrangement to achieve full-
wave rectification.
