The invention relates to high-voltage pulse technology and can be used in electrophysical

installations for receiving high-voltage

pulse voltages.

The purpose of the invention is to increase the performance of the generator by increasing the steepness of the front of the generated pulse.

The drawing shows a schematic electrical diagram of the generator.

The pulse voltage generator is made according to the Arkadyev-Marx scheme and contains storage capacitors 1.1-1.8, compensating capacitors 2.1-2.9, charge-discharge resistors 3.1-3.14, dischargers 4.1-4.8, capacitors 5.1-5.5 formed by the cost-generating elements of the generator, and resistors 6.1- 6.14 resistive dividers. A load 7 is connected to the output of the generator. The first and second terminals of even storage capacitors 1.2,1.4,1.6 and 1.8 are connected to the first output compensating capacitors

2.2-2.8. The second pins of compensating capacitors 2.3,2.5 and 2.7, the first pins of which are connected to the first pins of even storage capacitors 1,2, 1.4 and 1.6, are connected to the second pins of subsequent odd storage capacitors 1.3, 1.5 and 1.7, the second pins of compensating capacitors 2.2, 2.4, 2.6 and 2.8, the first terminals of which are connected to the second output of even storage capacitors 1.2, 1.4 and 1.6, are connected to the first output of previous odd storage capacitors 1,1,1.3, 1.5, 1.7, parallel to the first and last storage capacitors 1. 1 and 1.8'connected additional compensating capacitors 2.1 and 2.9.

The pulse voltage generator works as follows.

Storage capacitors 1.1-1.8 and compensating capacitors 2.1-2.9 through the charge-discharge resistors 3.1-3.14 are charged to a voltage of 1) _o . After the end of the charge storage capacitor, and compensation capacitors 1.1-1.8 2.1-2.9 4.8 for high-voltage switch _and a voltage is applied. When applying igniting pulses to the middle electrodes of the two lower dischargers 4.1 and 4.2, the triggering occurs. After operation of the two lower dischargers 4.1 and 4.2 on the middle electrodes of the dischargers located above them

4.3-4.7. Overvoltage impulses occur, under the influence of which these arresters operate. Capacities) formed by spark gaps 4.3-4.7 and ground and represented by capacitors 5.15.5, allow to improve the discharge characteristics of the generator. After the operation of all the gaps 4.1-4.7, the pre-charged to the voltage and _the compensating capacitors 2.1-2.9 form two branches connected in series through the activated gaps

4.1- 4.7 compensating capacitors

2.1- 2.9. In this case, the total voltage on the compensating capacitors 2.1-2.9, forming each of the branches, is applied to the high-voltage switch 4.8. Then, charging of compensating capacitors 2.2-2.8 occurs, i.e. all, except for capacitors 2.1, 2.9, to a voltage of 2C _O , since parallel to these capacitors, through dischargers 4.1–4.7, they are connected by two series-connected storage capacitors 1.1–1.8. Upon reaching a certain voltage value on the compensating capacitors 2.1-2.9, a breakdown occurs. high voltage switch 48 and a high voltage pulse is applied to the load 7.
