(57) Abstract:The invention relates to devices designed for energy conversion, DC input at DC current power output, and can be used as a power plant at the power consumers of interest in many fields of science and technology. The technical result is to expand the functionality of PV. The result is achieved by the fact that the proposed device is entered secondary source of power, the input of which is electrically connected to the feedback of the output of the PV. The invention relates to the physical power sources intended for energy conversion, DC input at DC current power output, and can be used in power supply systems of interest in many fields of science and technology.In modern research and production practice, the known device, the principle of which is based on successive conversion of the energy of the light radiation from the sun or an artificial source of light into electrical energy. All of these devices source electricity spacecraft (see Griliches Century A. space Solar power station, L. , 1986, S. 27). The practice of operating solar power plants shows that the lack of onboard spacecraft primary energy source allows you to avoid many difficult problems arising from the creation and operation of chemical and nuclear power plants, provides an opportunity to improve the reliability and safety of on-Board energy supply systems, while at the same time leads to some negative consequences. In particular, we must constantly focus solar power plant in the sun, and when flying on the partially shaded orbits must have onboard buffer electric power source (usually a chemical) for power users. These circumstances somewhat reduces the effectiveness of solar power plants.Known also PV, made in the form of high-voltage current source on the basis of coronarienne photovoltaic film (see and.with. USSR N 467786, class B 22 D 17/22, 1976). However, this current source has a high internal resistance and low discharge currents, which greatly reduces its functionality.Known devices of the knock pulse, containing a photocell-based coronarienne photovoltaic film, the primary power source, an artificial source of light, a trailer, and drive (see and. C. the USSR N 726415, CL F 42 S 11/00, H 02 M 3/00, 1980). In the case of light chain microfoliant sunlight or light from an artificial source, it generates a high voltage, reaching a value of 104CenturyGenerated by the photocell current high voltage, the availability of devices for mechanically adjusting the position of the plate relative to coronarienne photovoltaic film and electrostatic forces of interaction between them, are factors which reduce the reliability of the device and limits the scope of its application, which in turn testifies to the limited functionality.In all panels the process of converting the energy of light radiation into electrical energy is depending on the actual condition of natural or artificial light source, i.e. from the "light" and "dark" time, or "on-off" state of the electric current source, feeding the artificial source Sveti their functionality.The aim of the present invention is to expand the functionality of PV.This objective is achieved in that the PV that contains the primary power source, an artificial light source, the battery cells and the switching elements, introduced a source of secondary power supply in the form of piezoresistors Converter, which minimizes the dependence of the energy conversion process, the light emission energy of the DC output from the availability of energy briefly include a primary power source and the power output of PV input piezoresistors Converter, electrically connected feedback (see Art. "Feedback", Physical encyclopedia, so 3, S. 384, M., 1992: Physical encyclopedic dictionary, S. 477, M., 1983), ensures the continuity of the process of converting the energy of light radiation into electrical energy and the required duration of operation of the artificial light source and battery cells in a self-sustaining mode.The proposed device is structurally simple and does not require a graphical sobri forms of devices corresponding to a particular application by placing it in case necessary construction and use as the primary source of current electrochemical power source or Electromechanical transducer, and the like.One of the proposed device is a device consisting of a body placed container type serially electrically connected between the primary power source, the secondary source of power supply, electrically connected to the feedback of the output of the PV, the source of artificial light and optically connected with it battery cells.As the transmitter used power distribution Cabinet of appropriate dimensions, made of steel sheet metal, the lower and upper side walls which made the vents. One of the side walls has an opening with cover and constructive elements for the installation and maintenance of the primary power source, piezoresistance Converter, switching devices and terminal blocks. The front of the Cabinet features a single door having a sealing and locking elements required for maintenance of the battery cells and artificial light sources. On the top and bottom end of the enclosure in a plane parallel to the front surface of its installed cartridges on the new thread lamp is directed onto the photosensitive layer of the battery. Structural elements for the installation and mounting of batteries photo - elements and located between the rows of lamps made with regard to the batteries can be installed in pairs in a position oppositely directed relative to each other photosensitive layers. Includes installation of panels on back wall and the inner surface of the Cabinet door. Inside the Cabinet there are structural elements that are required for the installation and mounting of connecting wires. On the outer surface of the bottom end of the enclosure provides for the installation location and mounting the supporting elements.As the primary power source used compact battery nominal voltage: 12V CenturyAs a secondary source of power is used piezoresistors Converter with oscillator and piezoelectric transformer (see A. A. Erofeev, A. Danov, V. N. Frolov: Piezoelectric transformers and their application in electronics. M., "Radio", 1988, 3.1, S. 69-77, 3.2, S. 87-89.), high-voltage output of which is connected to the electrodes of the fluorescent lamps high-voltage wire of the appropriate execution, and the input is connected to the primary power source from a conventional fluorescent lamp 40W, mass-produced by the enterprises of electric light sources.Battery cells, the serial production of which is carried out by domestic plants, used as the primary power source PV.As switching elements are switches, sockets, cartridges, electronic relays, and similar performance of the relevant requirements of the "Rules for electrical installation".When applying for entrance piezoresistors Converter DC voltage to the value of 12, its output goes high-frequency alternating voltage of 1 to 2 kV, coming to the fluorescent lamp, creating a field of electromagnetic radiation between its electrodes. Under the influence of the energy of electromagnetic radiation is the excitement and the breakdown of the discharge gap, and then the stationary discharge in a fluorescent lamp. Simultaneous excitation of the phosphor inside the lamp. Light gas and the excited phosphor causes intense light radiation lamp.Under the influence of the energy of light radiation of the fluorescent lamp are excited photosensitive coatedthe with the principle of feedback, with one of the outputs of the battery cells through the switching elements of the circuit with a constant current 12 is input to piezoresistance Converter, the primary power source is automatically turned off, and the consequent conversion of electrical energy into the energy of light radiation and the energy of light radiation into electrical energy becomes self-sustaining.The simple design of the device and process of its Assembly, according to the degree of complexity compared with screwdriver technologies, and application as components, serially produced by the domestic industry, makes the organization of its production available to any company the electrotechnical industry. The PV containing the battery cells, the primary source of current, an artificial light source and switching elements, characterized in that it introduced electrically connected to the output of the battery cells, the source of the second power supply, the output of which is electrically connected with an artificial light source.
