Description

one

The invention relates to the formation of high voltage pulses and may be used in direct action accelerators.

The aim of the invention is to increase the stability of a series of generated pulses.

In the drawing, there are diagrams of current and voltage pulses in the device, realizing the proposed method,

 The drawing shows: a - diagram of the preliminary long-pulse signal unlocking the electronic switch; b — voltage diagram at the anode of the electronic switch; in - the diagram of the anode current of the electronic switch; g — diagram of accumulator stresses; d plot of charge current accumulator; e - the diagram of the switch start pulse series; W - diagram of the pulse series on the load.

The method for generating high voltage pulses is as follows.

A pulse is applied to the control electrode of the electronic switch, the duration of which is equal to the time of the transition process in the filter capacitor. The electronic switch is unlocked, the voltage at its anode decreases (plot b), a current flows through the electronic switch (chart c), the value of which increases in accordance with the time constant

| chain The magnitude of the maximum current at the end of the pre-impulse is set equal to the average current through the electronic switch in operation mode (plot c). In the process of forming a pre-pulse, the storage voltage decreases (epu r) and at the end of the process reaches a steady-state value, determined by the voltage drop across the elements of the power supply system. The duration of the preliminary impulse is set equal to the duration

and increase the reliability of the equipment, because Impact activation of a powerful accelerator leads to a transient process in the power supply system, which, in turn, leads to instability of the accelerating voltage and is accompanied by breakdowns in the accelerating gap.
