Automatic Voltage Regulator
Most of us heard about the word of “AC voltage regulator” in our daily lives. We
know that it is equipment attached to the television, to our computer or to the
deep freezer. Here we shall go deep into the working, specifications, and utilities
of an automatic voltage regulator. Automatic AC voltage regulator or AVR 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 an AVR 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 AVR or 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. We have
different appliances and equipment that use several AC or DC power source. These
devices are always accompanied with a voltage regulator. For instance, a laptopneeds
50 to 75 watts in order for it to power up. An oven toaster requires 1,200, an iron
1,000 watts, ablender 300 watts and a refrigerator for 1,200 watts. However, if
your oven toaster requires 1,200 wattsand you plug it to a power source of 700 watts,
what do you think can probably happen?In this case, the role of power regulator
plays a very important role in order to protect your appliance frompower surges.
Because of the regulator, it avoids fluctuation of power which can damage the differentdevices.
When the voltage runs too high or too low, electricity can harm those especially
sensitive appliances and equipment that you need in everyday life. Voltage regulator
can prevent these devicesfrom wear and tear and to prolong their life. What is its
function?Voltage Regulator is an electrical device that regulates voltage level
at all times. It may be designed as“feed forward” or may incorporate a negative
feedback control loops. It can utilize electrical componentsor electromechanical
mechanism. It functions by preserving a steady stream of electricity to the appliance
which may be disrupted during power surges such as power failures and lightning.
Except there isVoltage Controllers, power fluctuations may harm the appliance when
it is turned on and off. More Concrete IllustrationsA vehicle has generator and
a battery as the power source in order to maintain power level at all times. Sometimes
a car may run faster than any other times. This means the power must be regulated
at uniformheights in order for the car to work. The car Automatic Voltage Regulator
Generator assist inmaintaining a balance required output level and power output.
The power regulator in any device or appliance is designed to fit in them to control
the power output andthe voltage power level required. The regulators are tasked
to adjust a particular voltage excitation levelaccording to the equipment’s required
level. When there is a controller, the electric current can be steppeddown when
the power source is higher than the device’s required level. Here, the regulator
will take upthe excess power output and will only release the required limit of
1,200 in the case of the oven toaster.Different kinds of Voltage RegulatorsThere
are varieties of voltage regulators in the market ranging with different models
and makes. Each is designed to suit a particular device requirement. There are thousands
of them that are designed for alltypes of electric power and electronic equipment
by different Servo Voltage Stabilizer Manufacturers. AC Automatic voltage regulator
AVR 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 regulators are now replaced by digital AVR. 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 Saptech voltage regulators have different sizes. They are portable and easy
to handle. Some automatic voltage regulators 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 regulators and each has its own specifications. The variation
of AVRs can be judged by the names of automatic voltage regulators. Each name indicates
its specific functioning and differences from others and there are more than fifty
names to an automatic voltage regulator. Regarding the prices of automatic voltage
regulators, 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 regulator costs less
or high, it becomes irrelevant when it comes to the importance of an AVR in our
daily lives.
