ABSTRACT
This project is titled the design and construction of a 220V Automatic Voltage Stabilizer. A voltage stabilizer is an electrical
appliance used to feed constant voltage current to electrical gadgets like ACs and computers, and protects them from damage
due to voltage fluctuations. It works on the principle of a transformer, where the input current is connected to primary
windings and output is received from secondary windings. When there is a drop in incoming voltage, it activates
electromagnetic relays which add to more number of turns in the secondary winding, thus giving higher voltage which
compensates for loss in output voltage. When there is rise in the incoming voltage, the reverse happens, and, thus, the voltage
at the output side remains almost unchanged.
This project was designed to stabilize an AC input voltage of 160-250V to give an AC output voltage of 220V at 50Hz
automatically. The automatic feature can be achieved by the electronics devices used such voltage comparator IC, electromagnetic device (relay), auto- transformer and other electronics devices.

INTRODUCTION
1.1
BACKGROUND OF THE STUDY
Automatic AC voltage stabilizer is a wonderful invention of science, which is an electric device designed to regulate a
constant voltage in a settable level. The main working of a stabilizer depends upon the laws of electromechanical physics. It
is consist of many active and passive electrical components like adopters, capacitors, diodes and thermostats.
There are many functions of an automatic voltage regulator. AVR or automatic voltage stabilizer can be used with lot of
electric appliances for various reasons. The basic functions of the automatic voltage regulators are:
First and foremost, it is used as a rectifier and as a potential divider. Rectifier is also an electric device used to convert the
alternate current (A.C) to direct current (D.C) for further electric processing. Most of the electric appliances require a direct
current for their working and can’t work on alternate current. Regarding potential dividers, they are electric devices used for
the break out of input voltage to bring it to a desired output voltage as per the requirements. Thus while using an automatic
voltage regulator we can make use of a rectifier and a potential divider at the same time. Means you can save money because
you will have to buy a single automatic voltage regulator instead of purchasing a potential divider and a rectifier for your
electric appliances.
There are many appliances in our homes which need stable electric power for their running and there might be some damage
to the whole electric appliance if there comes any variation in the input current and voltage. Sometimes this may be fatal also
but electricity is a very merciless killer. To avoid any mishap to the electric appliances and to us also, which may arise due to
any variation in the voltage or current supply, a voltage stabilizer is essential to be used a complement to other electric
devices.
AC Automatic voltage stabilizer can also be used in amplifiers. Amplifiers are other electric devices that compare the sensing
voltages to the reference voltages and help to amplify the effect. You might have seen amplifiers attached to your home sound
systems which boost up the sound effects. The actual sound quantity will be lower but if the same input is given to an
amplifier, the resultant sound quality and quantity just increases to multiples of the input waves. The basic running procedure
in them is the difference of provided voltages. AC Automatic voltage regulators help in maintaining a desired voltage for the
generators within specified limits. Thus automatic voltage regulator is also the important part for our amplifier to work.
The previous analog/servo-types of automatic voltage stabilizers are now replaced by digital stabilizer. These types of
automatic voltage regulators are higher in functionality and performance. They are equipped with self functioning controls and
start up functions which make them very useful and easy to handle. Digital converters increase their precision levels.
Simplified operating switches make them very precise than human handlings. If any fault occurs in the functioning of the
automatic voltage regulators, self diagnostics technique detects the fault in no time. This leads to more security of the
function. The maintenance tool helps in maintaining an online monitor. Reduced number of parts and wiring in these typically
modern automatic voltage regulators make them more reliable. Automatic changes are easily dealt with the help of full duplex
control systems.
The NeoPower voltage stabilizers have different sizes. There are automatic voltage stabilizers which are so small that they can
be easily placed on a small printed circuit board. They are portable and easy to handle. Some automatic voltage stabilizers are
very gigantic in size. They may cover a volume of a small house sometimes. Thus there is a tremendous variety in the
automatic voltage stabilizers and each has its own specifications. The variation of stabilizer can be judged by the names of
automatic voltage stabilizers. Each name indicates its specific functioning and differences from others and there are more than
fifty names to an automatic voltage stabilizers. Regarding the prices of automatic voltage stabilizers, it goes the natural way. If
you will buy a smarter one, it will cost you more and you will buy an older model with normal functioning, it will cost you
less. But keep in mind that whether an AC automatic voltage regulatorcosts less or high, it becomes irrelevant when it comes
to the importance of a stabilizer in our daily lives.
1.2
PROBLEM STATEMENT
The rate at which our appliances get burnt is higher most especially appliances without transformer such as our cell phone
chargers and lanterns. And this problem is usually caused by either over voltage or under voltage. Due to this problems, a
voltage regulator was designed which regulates under and over voltages to normal 220vac. An automatic voltage regulator
regulates the AC voltage and keeps from lower or higher to normal. It protects any electronic device connected to it from
getting damaged.
1.2
OBJECTIVE OF THE PROJECT
The objective of this work is:
Provide a solution to under voltage and over situation faced by residents of high density areas of Nigeria by designing
and constructing an effective and comparatively cheaper voltage stabilizer which will have a cost price of less than total
cost obtained which could be afforded by most low income earners. This is cheaper than the ready made o factory
assembled voltage stabilizer of the same rating which goes for between.
To regulate the voltage of there is any over voltage or under voltage an regulate the voltage that will suit the purpose the
analysis design, construction and cost comparison have been done and necessary tests have been satisfactory out.
1.3
SIGNIFICANCE OF THE STUDY
As a student of electrical and electronic engineering, working on this project have expose my knowledge to function and
working principle of many electrics components such as voltage comparator, transistor, and mainly to auto-transformer. It has
made me to understand the working principle and application of stabilizer both in homes and industries.
1.4
THE SCOPE OF THE PROJECT
The design and construction of an Automatic Voltage stabilizer is the project we are constructing. We are working on this
machine because we have some idea on how this machine can be constructed and also on how it works. We are also doing this
because we want to learn more about it.
As we have mentioned earlier, this device is a protective device that protects our electrical and electronic appliances out of
current and voltage fluctuation. This is how it works. When this system is plugged into the socket or supply, it will receive a
minimum voltage of 100v and filter the current and voltage thereby brings out suitable voltage output to be used by the
devices in it.
So, we are building or constructing this device to reduce risk and damages the fluctuation of current / voltage caused by power
fluctuations.
1.5
LIMITATION OF THE PROJECT
The system design shall be capable of operating at an input frequency range of -15% to +10% of nominal, without clearing
protective devices or causing component failure within the AVS. When generator or utility power is restored, the AVR shall
automatically restart. Upon turn on or restart, the output of the AVR shall not exceed the specified output regulation limits.
If the input voltage or frequency exceeds programmable minimum or maximum set points for a programmable time period
(factory set for 10 seconds), the AVR shall electronically shut off. When electrical parameters are back within acceptable
limits for a programmable time period (factory set for 60 seconds), the AVR shall automatically restart to provide conditioned
power to the load. If the input parameters are within acceptable limits, but the output voltage is outside of acceptable
programmed limits, the AVR shall electronically shut off and require a manual restart.
