VOLTAGE STABILIZER

Learn what is a voltage stabilizer and its benefits, see types and tips for how to select right Automatic Voltage Regulator.
 
WHAT IS A VOLTAGE STABILIZER
 
A Voltage Stabilizer - It is also called as automatic voltage regulator (AVR) is an electrical device which is used to deliver a constant voltage output to a load at its output terminals irrespective of any change, fluctuation in the input i.e. incoming supply.

The basic purpose of a Voltage Stabilizer is to protect costly and precious electrical electronic equipments like air conditioners, offset printing machines, laboratory equipments, industrial machines, and medical apparatus from the probable damage due to Voltage Surges, fluctuations, Over/Under Voltage conditions.

TYPES OF VOLTAGE STABILIZERS

The inigitial Voltage Stabilizers came in the market were manually operated/ selector switch operated . These type of stabilizers used electro-mechanical relays for selection of desired voltage. With advancement of technology, added electronic circuits came into existence and the Voltage Stabilizers became automatic. Then came the Servo based Voltage Stabilizer which is capable of stabilizing the voltage continuously, without any manual intervention. Now, IC/ Micro controller based Voltage Stabilizers are also available which can perform additional functions too. The Voltage Stabilizers can be broadly categorized into three types. They are:

• Relay Type Voltage Stabilizers

In Relay type Voltage Stabilizers, the voltage is regulated by switching relays. The relays are used to connect the secondary transformer(s) in different configurations to achieve Buck & Boost function.

• Servo based Voltage Stabilizers

In Servo based Voltage Stabilizers, the voltage regulation is done with the help of servo motor. They are also known as Servo Stabilizers. They are close loop systems.

Advantages of Servo Based Voltage Stabilizer

 They have fast response to voltage fluctuations.
 They have high Voltage Stabilization accuracy.
 They are very reliable.
 They can withstand high voltage surges.

Disadvantages of Servo Based Voltage Stabilizer

 They need periodic maintenance.
 To nullify error, servo motor needs to be aligned. Alignment of Servo motor needs skilled hands.

• Static Voltage Stabilizers

A Static Voltage Rectifier has no moving parts as in case of Servo based Voltage Stabilizers. It uses a Power Electronic Converter Circuit to stabilize the voltage. These Static Voltage Stabilizers have very high accuracy and the voltage stabilization is within ±1%.

A Static Voltage Stabilizer contains ‘Buck & Boost’ transformer, Insulated Gate Bipolar Transistor (IGBT) power converter, Microcontroller, Microprocessor and other essential components.

Advantages of Servo Based Voltage Stabilizer

 They are very compact in size.
 They have extremely fast response to the voltage fluctuation.
 They have very high accuracy of voltage stabilization.
 As there is no moving part, it is almost maintenance free.
 They are very reliable.
 Their efficiency is very high.

Disadvantages of Servo Based Voltage Stabilizer

 They are costly as compared to their counterparts.

Problems Due to Voltage Fluctuation


 
WHY DO WE NEED VOLTAGE STABILIZERS?

All electrical/ electronic devices are designed and manufactured to operate at maximum efficiency with a typical voltage supply which is known as the nominal operating voltage. Depending on the designed safe operating limit, the working range (with optimum efficiency) of an electrical/ electronic device may be limited to ± 5%, ±10% or more.

Owing to many issues, the input voltage supply which we get always tends to fluctuate resulting to a constantly varying input voltage supply. This varying voltage is a major contributing factor for reduction of a device’s efficiency as well increase in its failure rate.

Nothing is more important for an electrical/ electronic device than a filtered, protected and stable power supply feed. A correct and stabilized voltage supply is very much required for the device to perform its intended function in the most optimized way. It is the Voltage stabilizer which ensures that the device get the desired and stabilized voltage no matter how much the fluctuation is. Therefore, Voltage stabilizer is a very efficient solution for anyone who desire to get an optimum performance and protect their devices against these unpredictable voltage fluctuations, surge and noise present in the supply.

Like UPS, voltage stabilizers are also an asset to the protection of electrical and electronic equipment. The voltage fluctuations are very common irrespective of where ever you live. There may be various reasons for the voltage fluctuation such as electrical faults, faulty wiring, lightning, short circuits, etc. These fluctuations may be in the form of Over voltage or Under voltage.

Effects of Over Voltage to the Electrical/Electronic Equipments

 It may cause permanent damage to the connected device.
 It may cause damage to the winding insulation.
 It may lead to unnecessary disruption in the load.
 It may lead to over-heating of the cable or device.
 It may degrade useful life of the device

Effects of Under Voltage to the Electrical/Electronic Equipments

 It may lead to equipment’s malfunction.
 It may result in low efficiency of the device.
 The device in some cases can take extra hours to perform the same function.
 It may degrade performance of the device.
 It may lead the device to draw large currents, that may further cause over-heating.

 
 
 
 
Basic Function of Stabilizer


 
HOW A VOLTAGE STABILIZER WORKS?

The basic work of a Voltage Stabilizer is to carry out two necessary functions i.e. Buck and Boost function. Buck and Boost function is nothing but the regulation of a constant voltage from over voltage and under voltage circumstances. This Buck and Boost function may be carried out manually with the help of selector switches or automatically with the help of additional electronic circuits.

During Over voltage circumstances, Buck function does the necessary reduction of voltage intensity. Similarly, during Under voltage circumstances Boost function increases the voltage intensity. The idea of the both the functions as a whole is to maintain the same voltage output.

Voltage stabilization involves addition or subtraction of voltage from the primary voltage supply. To perform this function, Voltage Stabilizers use a transformer that is connected to switching relays in various required configurations. Few of the Voltage Stabilizers use a transformer having various taps on its winding for providing various voltage corrections while few Voltage Stabilizers (such as Servo Voltage Stabilizer) contain auto transformer for providing the desired range of correction.
