Fluctuations in the parameters of the electrical network are often found in domestic conditions, where special means of protection in the form of stabilizing equipment are not provided. Voltage drops are the most dangerous phenomenon that adversely affects the operation and technical condition of electrical appliances. Both compact light bulbs and large-sized expensive equipment can burn out as a result of a sharply changed load on the network. An inverter stabilizer will help minimize such risks, leveling voltage losses.

The principle of operation of the device

The design of the device includes input filters, capacitors, converters and microcontrollers. By means of correctors and power rectifiers, balancing of the electrical parameters of the network is achieved. Directly the task of inversion, that is, converting direct current into alternating current, is performed by transistors. As a rule, this is a combination of bipolar IGBT elements provided with insulated gates. Also, the design may include metal-oxide MOSFET semiconductors.

In the process of working, a conventional inverter stabilizer for homeprovides switching of currents in order to correct the voltage by changing the polarity on the load regulators. These operations are controlled by a microprocessor, which, in particular, sets the control signals for network parameters. Also, the stabilizer chip, depending on the configuration, can solve the following tasks:

• Overload protection.
• Correction of key switching frequencies.
• Voltage adjustment.

Features of stabilizers for boilers

Heating equipment is characterized by high power, therefore, the requirements for the quality of energy supply are higher. Gas boilers are provided with electronics, the current sensitivity of which allows an error of 5% of 220 V. For proper electrical support of an explosive unit, an inverter regulator with fast responses and the ability to control a large number of windings is required.

In this case, the minimum amplitude of voltage fluctuations will be ensured, which will increase the reliability of the boiler. Moreover, preference should be given to electronic rather than electromechanical devices. In any case, this applies to the choice of a stabilizer for gas equipment, the operating rules of which exclude the possibility of sparks in the vicinity. As for power, the average range is 500-1000 watts. An accurate calculation according to the boiler passport should also take into account an increase of 10-15% for the stock.

What is the difference between the stabilizerinverter type for refrigerator?

Kitchen air conditioning equipment also places high demands on mains power. In refrigerators, the greatest load falls on the compressor and electric motor. Although modern models are equipped with inverter control relays to mitigate peak loads, this does not eliminate the need for a stabilizer.

To begin with, it should be noted that a voltage drop of up to 160-170 V is critical for such equipment. In this case, overheating may occur, the control automation will turn off and the microprocessor will burn out. Traditional models can be combined with relay surge protectors, but it is better to choose a stabilizer for an inverter refrigerator from the electronic devices segment. Firstly, such models more easily tolerate temperature loads, and secondly, they can also create technological shutdown delays when necessary. The power level depends on the operating parameters of the refrigerator. Usually, two ranges are distinguished depending on the number of compressors (one or two): 1000-1500 W and 1500-2000 W.

DAEWOO DW-TM5kVA

The best option for apartments provided with a standard set of electrical appliances. A power of 5000 W may not be enough for comprehensive maintenance of household appliances, but when 2-3 devices are allocated, it will be enough. Moreover, the stabilizer is based on a microprocessor, so the reactions occur at high speed and point-to-point generate correction signals.

A bypass function is also provided. itmeans that the DW-TM5kVA inverter voltage stabilizer 220 V can be left with direct current input in cases where rectification of the characteristics is not required. This feature allows you to save energy even when the equipment is turned on. Additional stabilizer protections include overload elimination, overheating mode up to 120 °C, short circuit prevention mechanism, etc.

Model "Shtil InStab-1500 R"

Basic solution focused on servicing specific household devices - for example, the same boiler or refrigerator. The model is equipped with a double current conversion system with instant voltage regulation. During operation, this 220 V inverter stabilizer provides a correction with an accuracy of 2%, that is, approximately 4-5 V. In comparison, fluctuations with deviations of 15-20 V are acceptable even in highly sensitive and responsible equipment.

The power of the device is 1125 W, which allows servicing pumps, climate control equipment, computer equipment, TVs, etc. The power potential is small, but the equipment is small and has a modest weight of 3 kg. The Shtil inverter stabilizer of this version has a modern microprocessor control system without a transformer based on IGBT transistors, which increases the efficiency of electrical protection with minimal power consumption.

Model "Resanta ASN 12000/1 C"

This version of the stabilizer will help to comprehensively provide allelectrical equipment in the house protection against voltage surges. Power of 12,000 W is enough to filter out frequency interference for lighting systems, kitchen appliances, multimedia equipment and other devices. Control of work is carried out by means of the integrated microprocessor with an error of 8%. The range in which the Latvian inverter stabilizer operates extends from 140 to 260 V. If the voltage limits are reached, an emergency shutdown occurs.

Conclusion

The rejection of classical electromechanics in the development of converters and transformers has raised the quality of protection of household appliances to a new level.

Electronic inverter voltage stabilizer for 220 V provides more opportunities for regulating current parameters, corrects network drops with high accuracy, and also provides for the possibility of a differentiated approach to working with different groups of target equipment. The only weak point of such devices can be called the cost. For example, models from the above-mentioned manufacturers of electrical equipment in the middle link are available for 10-15 thousand rubles.
