Description

(54) LOADING SUPPLY DEVICE The invention relates to electrical engineering and can be used to supply a load from chemical current sources. A device for supplying a load is known, which contains a battery made in the form of a housing and electrodes immersed in an electrolyte solution 1 as a current source. However, this device does not provide a constant supply voltage due to the presence of the incident voltage in the battery. of the duration of the bits. It is also known a device for supplying a load, containing an accumulator made in the form of a conductor and electrodes immersed in an electrolyte solution, and an excitation winding used to stabilize the discharge voltage, and part of at least one of the electrodes is made of a magnetostrictive material and the field winding is connected to a high frequency current source and covers the magnetostrictive part of electrode 2. The disadvantages of the known device are the design complexity, low reliability, large gab Ita and weight. The purpose of the invention is to simplify the design, increase the reliability and improve the overall mass indicators of the device. The goal is achieved by the fact that in a device for supplying a load containing an accumulator, made in the form of a housing and electrodes immersed in an electrolyte solution, and an electromechanical converter connected to a high-frequency current source and used to stabilize the discharge voltage in the lower part the body houses a membrane, and the electromechanical transducer is designed as a piezoelectric plate mounted on the membrane with two insulated electrodes located on its main faces and connected to a high frequency current source. The drawing shows the proposed device, the cut. The device for supplying the load comprises a battery case 1 with an electrolyte solution 2 and electrodes 3 and 4 immersed in an electrolyte solution. The lower part of the body is made in the form of an elastic steel membrane 5, to which a piezoelectric plate 6 is glued with insulated electrodes 7 and 8 on the main faces. External consumers (not shown) are connected to the output terminals of the electrodes 3 and 4. The isolated electrodes 7 and 8 of the piezoelectric plate are connected to the ultrasonic generator 9, which is under the influence of the regulator 10, intended to process the information on the change in the discharge voltage of the battery and for maintaining the output voltage of the ultrasound generator is proportional to the magnitude of this change.

The device for powering the load works as follows.

An electrical signal proportional to the actual discharge voltage of the battery is supplied from the battery electrodes to the regulator 10. The latter processes information about the change in the discharge voltage of the battery and outputs an electrical signal to the input of the ultrasonic generator 9, the value of which is proportional to the nominal difference and actual battery discharge voltages. The generator 9 converts the electrical signal arriving at its input into a high-frequency voltage that feeds the electrodes 7 and 8 of the piezoelectric plate 6. The electric field between the electrodes causes alternating deformation of the compression of the piezoelectric plate 6, which causes the elastic membrane 5 to oscillate. Ultrasonic cola; membrane baths 5 intensifies electromechanical processes in the formula of the invention

The proposed design of the device avoids the use of an excitation winding, which makes it possible to simplify its design, increase reliability, and improve overall mass parameters. In addition, the efficiency of the device is improved due to an increase in the efficiency of the electromechanical converter. In this case, the absence of radiated magnetic fields is also achieved, the possibility of using the device for various designs, shape, materials, dimensions of the battery electrodes and expanding the operating frequency range of the electromechanical converter
