The disadvantage of this stabilized AC voltage to constant voltage converter is the high copper consumption of the primary winding, since it is designed for the full voltage of the alternating voltage source, and a high 3 operating voltage on the non-linear oscillation capacitor. The purpose of the invention is to improve the energy and technical and economic indicators by reducing the operating voltage on the capacitor and reducing the consumption of copper on the primary winding. This goal is achieved by the fact that in a stabilized AC-to-DC converter, containing two rectifiers, a capacitor and two transformers, made on one three-core magnetic core, on the middle core of which is located the primary winding, one end of which is connected to one of the terminals through a capacitor for connecting a source of alternating voltage, on the extreme rods ifflx are secondary windings, two of which are connected in series, forming a circuit connected to the leads for connecting a source of the alternating voltage, and each of the other two is made with an average output and connected to the corresponding rectifier, the average outputs of these secondary windings are combined and their common point forms one of the output terminals, and the other output terminal is formed by the common connection point of the power terminals of the same name the electrodes of the gates of the two outlets, one of the secondary windings of the series circuit, is made with a tap off part of the turns to which the second end of the primary winding is connected. The drawing shows a diagram of stabilized variable voltage to constant voltage converters. The stabilized converter contains two transformers made on the same magnetic core 1, on the central rod of which the primary winding 2 is located, one of the outputs of which is connected through a capacitor 3 to one of the terminals for connecting the source of alternating voltage 4, the other to the part of the secondary winding 5 located on the outermost core of the magnetic circuit and forming a circuit connected to the other secondary winding 6, connected to the terminals for connecting the source to reverse the voltage 4 directly. The codes 7 and 8 are connected according to the scheme with a midpoint, and C1) only the outputs of the secondary windings 9 and 10 are closed and connected to the load 11. The stabilized converter works as follows. When power is applied from a source of over 9440234 voltage to the windings of the trainformers, nonlinear parametric oscillations arise in them. As a result of these oscillations between the voltages applied to rectifier bridges 7 and 8, a phase shift of 90 ° occurs. After the rectifier, these stresses in the warehouse 1 are loaded at 11, as a result of which the main harmonics in the rectified voltage are shifted to ISO and in the limit are eliminated. The use of this invention allows to reduce the consumption of copper on the primary winding and the operating voltage on the capacitor.
