Applications of Voltage Stabilizers have became a need for every home. Different types of Voltage stabilizers are available now with different functionality and works. The latest advancements in technology like Microprocessor chips and Power Electronic Devices have changed the way we see a Voltage Stabilizer. They are now fully automatic, intelligent and packed with a lot of additional functions. Even the ships, who have their own internal power supply arrangement in form of Diesel Alternators, are heavily dependent on these AVRs for safety of their equipment.

We can see different types of Voltage Stabilizers available in the market. Both analog and digital automatic Voltage Stabilizers are available from so many manufactures. Thanks to the rising competition and increasing awareness for the safety devices. The regulation of desired stabilized output is done by buck and boost method as performed by its internal circuitry. Three phase Voltage stabilizers are available in two different models i. Balanced load models and Unbalanced load models.

They are available in different KVA rating and ranges too. A normal range Voltage Stabilizer can ensure a stabilized output voltage of volt with volt boost-buck from an input voltage feed ranging from volt to volt. Whereas, A wide range Voltage Stabilizer can ensure a stabilized out voltage of volt with a volt boost buck from an input voltage ranging from volt to volt. They are also available for wide variety of applications such as dedicated voltage stabilizer for small units like TV, Refrigerator, Microwave ovens to a single huge unit for an entire house hold appliances.

Owing to many issues, the input voltage supply which we get always tends to fluctuate resulting to a constantly varying input voltage supply. 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. The basic work of a Voltage Stabilizer is to carry out two necessary functions i. 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.SlideShare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

V guard synopsis. Business research Synopsis: Impact of brand awareness on consumers attitude t Related Books Free with a 30 day trial from Scribd.Here we will study the design of a simple automatic mains AC voltage stabilizer which can be applied for safeguarding appliances like TV and refrigerators from fluctuating voltages.

A voltage stabilizer is a device which is designed to sense inappropriate voltage fluctuations in AC mains supply inputs, and correct them to produce a stabilized voltage for the connected appliances or gadgets. Referring to the figure we find that the proposed automatic voltage stabilizer circuit is configured with the single opamp IC It becomes the control section of the whole design. The opamp is wired as a comparatorwe all know how well this mode suits the IC and other opamps.

It's two inputs are suitable rigged for the said operations. Pin 2 of the IC is clamped to a reference level, created by the resistor R1 and the zener diode, while pin 3 is applied with the sample voltage from the transformer or the supply source. This voltage becomes the sensing voltage for the IC and is directly proportional to the varying AC input of our mains supply.

The preset is used to set the triggering point or the threshold point at which the voltage may be assumed to be dangerous or inappropriate. We will discuss this in the setting up procedure section. In case the the mains voltage crosses a predetermined threshold, the ICs non inverting detects it and its output immediately goes high, switching ON the transistor and the relay for the desired actions. The relay, which is a DPDT type of relay, has its contacts wired up to a transformer, which is an ordinary transformer modified to perform the function of a stabilizer transformer.

The relay contacts are appropriately integrated to the transformer taps for executing the above actions as per the commands given by the opamp output. So if the input AC voltage tends to increase a set threshold value, the transformer deducts some voltage and tries to stop the voltage from reaching dangerous levels and vice versa during low voltage situations. If a resistor divider was used instead of a zener at pin 2, the relationship between the reference level at pin 2 of the opamp with the resistor divider and Vcc could be given as:.

You will require the following components to make this homemade automatic mains voltage stabilizer circuit:. The discussed simple automatic voltage stabilizer circuit may be set up with the following steps:.

What is Voltage Stabilizer & How it Works?

Now, using a variable power supplypower the circuit across C1, the positive of the supply goes to the pin 7 line of the opamp while the negative goes to the negative pin 4 line of the opamp. Set the voltage to about Remember, here we have assumed that the DC output For your circuit be sure to confirm this before doing this set up procedure.

Now lowering the voltage to about 12 volts should make the opamp trip the relay to its original state or make it de-energized. Repeat and check the relay action by altering the voltage from 12 to 13 volts, which should make the relay flip flop correspondingly. Now you may connect both the transformer to its appropriate positions with the circuit, and also restore the R3 and the relay connections across their original points. When installed, the relay trips whenever the input voltage crosses volts, bringing the output to volts and keeps this distance continuously as the voltage reaches higher levels.

When the voltage drops back tothe relay gets de-energized pulling the voltage to volts and maintains the difference as the voltage further goes down.

The above action keeps the output to the appliance well between to volts with fluctuations ranging from to volts. Warning: A single wrong connection could lead to a fire hazard or explosion, therefore please proceed with caution. Always use a watt protection bulb in series with the one of the mains line which goes to the stabilizer transformer initially.

Once the operations are confirmed, you can remove this bulb. If you have any circuit related query, you may interact through comments, I'll be most happy to help! Your email:.

An ideal circuit for home to protect your valuable equipments from voltage fluctuations.

The same circuit with some modifications can be used to make a automatic voltage stabilizer. When the mains voltage is in the normal level, the voltage at the negative terminal of zener diode D4 will be less than 5. At this condition transistor T1 will not conduct. The same time voltage at the negative terminal of zener diode D5 will be greater than 5. The relay will be activated and the green LED will be glowing.

When the mains voltage is higher than the set limit the transistor T1 becomes conducting since the voltage at the negative terminal of D4 is greater than 5. At the same time transistor T2 will be non conducting which results in the deactivation of relay to cut the mains supply from load.

The timer NE is wired as a monostable multivibrator with a pulse width of 10ms. When the power comes back after a cut off a negative voltage is obtained at the trigger pin which triggers the IC NE The transistor T3 gets forward biased and it drives the buzzer to produce a beep as an indication of power resumption. Also the transistor T1 is made on which in turn makes T2 off. As a result the relay will remain de- activate for 10ms and this provides the sufficient delay and the equipment is protected from surge voltages.

It should be connected to input supply circuit. Connect this unit to incoming supply and out put to equipment which requires protection.
