Full Wave Rectifier


To design and study a Full Wave Rectifier.


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

A full wave rectifier is a device which is used to rectify all the alternating current components in an alternating supply and make it purely a direct current. The two alternating halves of an alternation current are rectified in a full wave rectifier which is an advantage over a half wave rectifier. Most electronic devices cannot withstand very high voltage or alternating current due to its intense high power. The use of batteries in all devices is not practical as their replacement and durability is a huge problem as the device has to be dismantled each time for such a replacement. So these rectifiers are used in most of the electronic devices like TV’s, Radios, Chargers, and Lightings etc. There are several stages in a rectifier. Based on their rectification they are classified into two. The single staged & multi staged.

In the multi staged rectifiers, more than two diodes are used and these are used in the above-mentioned devices. The singled staged rectifier has only two diodes, the one we are to discuss in this project. The multi diode rectifier has only 2 diodes, the one we are to discuss in this project. The multi diode rectifiers have efficiency ~94.6% while that of the single is only 81.2%.
