The invention relates to electrical engineering, is intended to convert electromagnetic energy and can be used as a source of high constant voltage to supply X-ray and other electrophysical equipment.

The purpose of the invention is to increase reliability.

The drawing shows a cascade generator section.

The device contains a magnetic core 1, a primary winding 2, four secondary windings 3-6, connected respectively to rectifiers 7-10 and separated from the primary winding 2 by electrical insulation 11. The latter is separated by open coaxially electrically conducting cylinders 12-15, made with decreasing as they move away from their axis. Cylinders 12-15 are electrically connected respectively to the like terminals of secondary windings 3-6.

The device works as follows.

When connecting the primary winding

2 to a source of alternating voltage in the secondary windings 3-6 are applied to the voltage that the rectifier is 7-10 are rectified and since the rectifier 7-10 are connected in series, the output voltage of the generator is equal to the sum of the voltages at the rectifier outputs - tely. Due to the fact that the voltage between the same terminals of the adjacent secondary windings is equal to the voltage at the output of one rectifier, there are voltages between two adjacent cylinders that are equal to the output voltages of the rectifiers. In this case, the voltage applied to the insulation 11 is distributed uniformly over its thickness. Since ksk constructive capacitances formed by each pair of adjacent cylinders significantly exceed the capacitance between other structural elements, then the potentials of the secondary windings 3-6 with respect to the common point of the generator circuit grow with a constant step equal to the output voltage of one voltage. mittel, from the first secondary winding 3 to the last secondary winding 6.

between the cylinders 12-15, the output voltage is filtered, thereby reducing the ripple of this voltage.

When connecting the insulating cylinders to the same terminals of the secondary windings, capacitive currents caused by parasitic capacitances between each of the secondary windings and the cylinders connected to them are practically excluded. The potentials of the secondary windings grow with a constant step, as defined. They are mainly made by containers between adjacent cylinders. Due to the fact that the secondary windings are located relative to the surrounding elements identically, the uneven loading of the secondary windings is reduced.

The potential of the secondary windings grows with a constant step equal to the output voltage of a single impedance j as determined by the capacitances between the cylinders, whose values exceed the values of the parasitic capacitances, thereby reducing the likelihood of breakdowns FROM and increasing reliability due to reduced currents flowing; by parasitic capacitances, due to the fact that a constant voltage is applied to a significant part of them.
