Introduction :

Embedded microprocessor chip technology and power electronic devices in the design of AC voltage regulators (or AVR) lead to the generation of high-quality, stable power supplies in the event of significant and consistent voltage supply of the power supply. .
As advanced relay voltage regulators are advanced, modern stabilizers utilize high-performance digital control circuitry and solid-state control circuitry that eliminates potentiometric settings and enables the user to adjust the voltage required through a keypad Slowly

It also leads to timing or response of the stabilizer to a much lesser extent, usually in less than a few milliseconds, in addition to it can be adjusted with Variabell. Today, the stabilizers are an optimized solution for many electronic devices that are sensitive to voltage fluctuations and work with many devices such as CNC machines, air conditioners, televisions, medical equipment, computers, telecommunication equipment, etc. has it.

What is a Voltage Stabilizer (Home Stabilizer)?
The voltage stabilizer is an electrical device designed to provide a constant voltage at a single load at its output terminals, regardless of the input variation or voltage of the input source. This device protects against high voltage and other voltages.
It is also called the Automatic Voltage Regulator (AVR). Voltage stabilizers are preferred for expensive and expensive electrical equipment to protect against low volatility and volatility. Some of these equipment include air conditioning, offset printing, laboratory equipment, industrial machinery and medical devices.

Voltage stabilizers adjust the voltage inlet voltages before they can be loaded (or equipment that is sensitive to voltage variations). The output voltage of the stabilizer in the range of 220 and 230 volts in the case of single phase supply and 380 volts or 400 volts in the case of the supply of three phases is within the range of the input voltage. These regulations are enforced by additional functions reinforced by internal circuits.
There are several types of automatic voltage regulators available on the market today that can be single or three-phase units, which are required depending on the type of program and capacity (KVA). Three-phase stabilizers are available in two versions as balancing models and unbalanced load models.
Stabilizers are specifically available for household appliances or as a large stabilizing unit for household appliances in a specific location. Additionally, they can be a type of analog or digital unit stabilizing unit.

Typical types of voltage stabilizers include manual stabilizers or switching, auto stabilizer stabilizers, solid stabilizers or stabilizers and servo control stabilizers. In addition to the stabilizer function, most stabilizers have additional features such as output / output / output voltage, high voltage / I / O output, over-interruption, start-up and stop, manual / auto start, voltage output display, voltage switching Zero, and so on.

Why is Home Necessary Stabilizer Required?
In general, each electrical equipment or device is designed for a wide range of input voltage. Depending on the sensitivity, the operating range of the equipment is limited to certain values, for example, some equipment can withstand ± 10% of the rated voltage, while the other is ± 5% or less.
Voltage fluctuations (increase or drop in rated voltage) in many areas, especially in end lines. The most common reasons for voltage fluctuations, lighting, electrical faults, faulty wiring and cutting off the machine. These fluctuations have reached electricity and home appliances.

Basic principles of voltage stabilization In order to perform tank operation and amplification in a voltage stabilizer, voltage correction is performed from over-voltage and voltage conditions through two essential operations, ie, reinforcement and displacement operations. This operation can be done manually with switches or automatically via electronic circuitry. During the voltage state, the voltage amplification operation increases to the rating level, while the tissue function reduces the voltage under high voltage conditions.
The concept of stabilization involves adding or subtracting the voltage to and from the power supply. To do this, the stabilizer uses a transformer that is connected to the switching relays in various configurations. Some stabilizers use a coil-operated transformer to correct the different voltages, while servo stabilizers use an automatic transformer to have a wide range of modifications.
To understand this concept, let us consider a simple 230 / 12V transformer and its relation to this operation is presented below.

The above figure shows the amplifier configuration in which the secondary coil polarity is adjusted so that its voltage is directly added to the initial voltage. Therefore, in the case of voltage status, the transformer (whether it can be changed or auto-transformer) is powered by relays or solid-state switches so that additional voltages are added to the input voltage.

In the figure above, the transformer is connected in the bucking configuration, while the polarity of the secondary coil is such that its voltage is eliminated from the initial voltage. The circuit switches over to the load over the overload voltage to this configuration.

The above figure shows the two-stage voltage stabilization using two relays
