Unit name: Full wave Bridge type rectifier Total 5 Hours
Topic: Full wave Bridge type rectifier

Sub Topic:

1. Bridge rectifier
2. Diode bridge rectifier
3. Positive cycle
4. Negative half cycle
5. Full wave rectifier with smoothing capacitor
6. Bridge rectifier ripple voltage

Key Features

Bridge is a type of electrical circuit. Bridge rectifier is a type of rectifier in which diodes
were arranged in the form of a bridge. This provides full wave rectification and is of low cost. So
it is used in many applications. A diode bridge is an arrangement of four (or more) diodes in
a bridge circuit configuration that provides the same polarity of output for either polarity of
input. Another type of circuit that produces the same output waveform as the full wave rectifier
circuit above is that of the Full Wave Bridge Rectifier. This type of single phase rectifier uses
four individual rectifying diodes connected in a closed loop “bridge” configuration to produce
the desired output. The main advantage of this bridge circuit is that it does not require a special
center tapped transformer, thereby reducing its size and cost. The single secondary winding is
connected to one side of the diode bridge

Electronics Discussion in all English
terminologies they are all good listeners,

if they didn’t come up they don’t
hesitated to ask all the question that pop
up in their mind, having fun? Yes they

are!!

Hands on activity, from beginners to
professional technicians

For now you are a listener but
someday you will become a

good speaker!

English class let the student
memorize and write all the things
inside this classroom in English
form. From nothing to everything

English day!

Mobile phones are not
allowed inside my
classroom!

In the end of the day we all are friends and
English is our language inside this room to
connect each other.

Morning English Activity

Every morning we presented English word or
sentence to discuss what is the meaning of the
word/sentence and how to use the English sentence

in every situation.

Can you help us to spread the English word in this
college?

And also multimedia man we share every word
and sentence not only in this college but all
over world in Facebook Live streaming.
