Fluctuations in the parameters of the electrical network are often found in domestic conditions, where special protective equipment in the form of stabilizing equipment is 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 dramatically changed load on the network. To minimize such risks, an inverter stabilizer, leveling voltage losses, will help.
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 performance of the network is achieved. The direct task of inversion, that is, the conversion of direct current to alternating current, is performed by transistors. Typically, this is a combination of bipolar IGBT elements provided with insulated gates. MOSFET metal oxide semiconductors may also be included.
In the process, a conventional inverter stabilizer for the home provides switching 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 problems:
- Overload protection.
- Key switch frequency correction.
- Voltage regulation.
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% from 220 V. For proper electrical support of an explosive unit, an inverter stabilizer with fast reactions and the ability to control a large number of windings is required.
In this case, the minimum amplitude of voltage fluctuations will be provided, which will increase the reliability of the boiler. Moreover, preference should be given to electronic rather than electromechanical devices. In any case, this concerns the choice of a stabilizer for gas equipment, the operating rules of which exclude the possibility of sparks nearby. 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 an inverter type stabilizer for a refrigerator?
Climatic kitchen equipment also places high demands on mains power. For refrigerators, the largest load falls on the compressor and electric motor. Although modern models are equipped with inverter control relays to cushion peak loads, this does not negate 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 a technique. In this case, overheating, shutdown of the control automatics and combustion of the microprocessor can occur. Traditional models can be combined with relay line filters, but it is better to choose a stabilizer for an inverter refrigerator from the segment of electronic devices. Firstly, such models can 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.
Model DAEWOO DW-TM5kVA
The best option for apartments provided with a standard set of electrical appliances. A power of 5000 watts may not be enough for comprehensive maintenance of household appliances, but with the allocation of 2-3 devices it will be enough. Moreover, the stabilizer is based on a microprocessor, so the reactions occur at a high speed and generate correction signals pointwise.
A bypass function is also provided. This means that the 220V inverter voltage stabilizer of the DW-TM5kVA modification can be left with a direct current input in cases where the rectification of the characteristics is not required. This feature allows you to save energy even when the equipment is turned on. Additional means of stabilizer protection include the elimination of overloads, the mode of operation during overheating up to 120 ° C, the mechanism for preventing short circuits, etc.
Model "Calm InStab-1500 R"
A basic solution focused on servicing specific household appliances - for example, the same boiler or refrigerator. The model is equipped with a dual current conversion system with instant voltage regulation. During operation, this 220 V inverter stabilizer provides correction with an accuracy of 2%, that is, approximately 4-5 V. In comparison, even highly sensitive and demanding equipment accepts vibrations with deviations of 15-20 V.
The power of the device is 1125 W, which allows servicing pumps, HVAC equipment, computer equipment, televisions, etc. The power potential is small, but the equipment is small and modest in weight of 3 kg. The Shtil inverter stabilizer of this version provides 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 Ts"
This version of the stabilizer will help to comprehensively provide all electrical equipment in the house with protection against voltage surges. Power at 12,000 watts is enough to filter the frequency interference for the lighting system, kitchen appliances, multimedia equipment and other devices. Work control is carried out by means of an integrated microprocessor with an error of 8%. The range in which the Latvian inverter stabilizer operates, extends from 140 to 260 V. In the event of reaching the voltage limits, 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.
An electronic inverter voltage stabilizer for 220 V provides greater possibilities for regulating current parameters, corrects drops in the network with high accuracy, and also provides the possibility of a differentiated approach to working with different groups of target equipment. The only weak point of such devices is the cost. For example, models from the above-mentioned manufacturers of electrical equipment in the middle link are available for 10-15 thousand rubles.
