It is known, that the voltage deviation from the nominal value leads to a change in the technical characteristics of the equipment and may cause a violation of their working ability, including leading to an emergency. The article deals with the known structural diagram of single-phase voltage stabilizers of AC power, the peculiarities of their work and their disadvantages. To improve the performance characteristics of single-phase AC voltage stabilizers, we have proposed a functional scheme of the stabilizers performed on transformers, autotransformers and optosymistors. The article considers features of the proposed circuit voltage stabilizers. To stabilize three-phase voltage we have proposed using a three-phase stabilizer. In this case, to improve the reliability of the reserve there may be a single-phase stabilizer, which automatically connects to the appropriate phase at malfunction of one of the working electronic voltage stabilizers. To stabilize three-phase voltage, a stabilizer can be made based on the three-phase transformer. In comparison with the use of a single-phase stabilizer in a three-phase system, the voltage stabilizer will have improved weight and overall dimensions. To significantly improve the technical characteristics of voltage stabilizers, working in the autonomous power supply systems, it is possible only through the use of modern mathematical apparatus, allowing to simulate the physical processes in power circuits of stabilizers in nominal and emergency modes of operation

The absence of theoretical bases for interaction of the magnetic field and cellular mechanism, the lack of an effective way to determining the results of this action has led to the creation of a large number of machines and devices of electromagnetic influence on biological objects of vegetable and animal origin. Many of them are contain special generators and inductors developed for a specific type of object. By means of these constructions, used in electro technological processes at agricultural companies of the Kuban region, we increase productivity of different crops, increase productivity of animals and poultry, change the physical and chemical properties of liquids and solutions, conducted in boiler water preparation. A distinctive feature of the electromagnetic field processing of objects of biological origin is sufficiently high efficiency of outcomes at insignificant energy costs. All this foreshadows further improve the long-term development and research in this area. By analyzing the existing devices, it can be concluded, that all of presently available designs for electromagnetic treatment are classified by a common attribute - a method for creating a magnetic field. The lack of reliable, logically complete theory of influence of electromagnetic influence on biological systems agricultural purpose and the availability of practical recommendations when to use inductors working on constant, and when the AC has led to the fact that to obtain the necessary effect, share the same devices have become connected to various sources of supply

The article covers the basics of thermodynamics and the possibility of the application of its provisions to the basic biological entity - the cell under the influence of external electromagnetic fields. Thus, we consider a system whose properties do not change in time, if it does not occur on the external influences. If the system is subjected to such (mechanical, thermal, electrical, magnetic and other effects), then all its properties, or some of them are changing. If at least one property of the system changes, we will talk about changing the status of the system due to the fact that there was some process. From the point of view of external electromagnetic fields on the thermodynamic system - a cell of a living organism or plant is very important essence of the concept of work. Unlike conventional concepts of the work of expansion (pdV), which is not considered to be useful, we have introduced the concept of "useful" work dA /, which means the operation of the electric current, magnetic field or other physical fields in the design of various electrical devices and appliances used in livestock and crop. The impact of electromagnetic fields on biological objects also leads to a slight increase in temperature of the biological system and, as a consequence, it increases the rate of chemical and biochemical reactions and phase transitions, which is reflected in the increased activity of the biochemical processes in these objects. This, to some extent can explain numerous experimental results of scholars and practitioners concerned with stimulating crops, for example, during preplant treatments

Creating an efficient, competitive agricultural production, ensuring food security of the country, increasing exports of certain agricultural products - the most important strategic goals of agri-food policy. Using the energy of the electromagnetic fields of different frequencies significantly complements electrotechnology. The widespread use of devices electromagnetic effects on biological systems in agricultural production and promising in terms of cost of the mechanism in the design, manufacture and operation of such devices. Thus, the resulting yield increase after preplant seed treatment in a magnetic field averages for various sources, including the data of our investigations from 10 to 22% depending on the type of crops. The economic effect of the introduction is quite high due to the low energy consumption (power plants to many 1kW), simple and reliable operation of technical designs themselves aids. The experimental data of domestic and foreign researchers indicate increased biological activity using electromagnetic fields (EMF) in all frequency ranges. However, further development of biological objects of electromagnetic devices are not possible without the introduction of the theoretical foundations of their construction. For this purpose, it is necessary to use numerous existing studies of the behavior of biological objects processed agricultural use in the electromagnetic fields of artificial origin

For explaining the regulatory mechanisms of biological the methods of classical biology, chemistry and physics are clearly inadequate, since the structure and function of these mechanisms are determined by the motion of the electron clouds in conjugated molecules. This "movement" can lead eventually to a complex organization called life only if they are subject to certain static laws and, therefore, may eventually be known in all the complexity of their relationships. Biological objects, resulting in the evolution of the environment, are like a part of that environment. Information stored in the seed, based in its deployment on energy and material resources of the environment. Moreover, in the process of development body derives more information from the environment. Nature has the extreme complexity and diversity. Examples include a huge variety of organisms, the complexity of atomic processes, the structure of the solar system and the stellar galaxies. There are four types of different interactions with the help of which we describe all physical phenomena. Today, it seems to us that all the various manifestations of the nature of elementary particles are reduced to the action between them of these four kinds of forces. The most famous of these are the gravitational Zion and electromagnetic forces, which are directly manifested in the world around us. Gravity allows us to stay on the Earth and allows planets to stay in their orbits. Electromagnetic interactions of electrons inside atoms and molecules cause all known chemical and physical properties of ordinary solids, liquids and gases and, in addition, are the basis of all of the processes occurring in living organisms. Research in the field of magneto proved that the biological systems are selectively susceptible to the action of electromagnetic fields as a function of their intensity, exposure time and frequency
