Things to Know About Power Diode
Power diode is a device that is made used
for converting AC to
DC. It is a crystalline semiconductor and
the process t carries
out is called as rectification. This can be seen
in the circuits
of power supply available with most
of the electrical and
electronic equipments that are available in
market. It has a
function similar to that of a mechanical one
way valve. It
is capable of conducting electrical
current with lesser
resistance in a direction called as forward
direction and it also
prevents current from flowing to opposite
direction. It can be
of greater help in passing numerous ampere of
current forward and
also has got PN junctions that are larger in
size. It has got higher
capacity for carrying forward current that the
other signal diodes.
There is possibility for finding better and
more information
regarding its applications in utsource.net.
There are various kinds of power diodes available
in the market,
which are meant for different uses. These diodes
are rated as per
the maximum amount of current that they can carry
in the forward
direction and also the maximum amount of reverse
voltage that they
can overcome. Because of resistance, there is
possibility to see
a smaller voltage drop when current is passing
through the power
2
diode in forward direction. It can also withstand
only a certain
amount of voltage in reverse direction
and if the voltage
exceeds this limit, the device stops
working.
These devices are made out of silicon and
also have traces of
certain other materials too in it which
include phosphorous,
germanium, arsenide, gallium and Boron. A single
diode can convert
AC to DC but this conversion can be considered
only as a half wave.
For a full wave conversion, two or more
diodes are connected to
circuit. Bridge rectifier is a simple
example for the full wave
convertor. It comprises of four power diodes
connected with each
other converting both negative and positive
sections of AC wave
to DC. This can result in what is called
rectification of full
wave.
In almost every part of the world, electricity
supply is available
in three phase AC. Electricity is
distributed in this form from
the power plant to houses and other
private places. Bridge
rectifier is capable of converting a full
wave but it is not
capable of delivering DC in constant
voltage that is necessary
for the modern equipments to operate. For
solving this issue
associated with bridge rectifier, a
reservoir capacitor is
3
connected to the end of rectifier. This can help
in smoothing out
the rippled voltage. It is necessary to have
contant voltage than
varying one for the proper functioning of
devices and also for
them to last for longer period of time.
This device can make it
possible for the homes to get better
voltage that can help in
making the appliances and tools function
effectively. You can

Choose the power diode that suits your
need and application.
