A coaxial marx generator

Abstract

The invention relates to a coaxial Marx generator. The generator is not only flexible and convenient to select a capacitance value, but also can fix the relative positions between parts in a movement,and can also achieve insulation. The structure mainly comprises a movement and a housing, wherein the coaxial Marx generator further comprises M first supporting cross beams; the movement comprises Nstages of capacitor groups and N / 2 gas switches; the N stages of capacitor groups are arranged in the housing along the axial direction of the housing in sequence, and each stage of capacitor groupscomprises a supporting ring and S capacitors, and the S capacitors are uniformly embedded in the inner ring edge of the supporting ring along the circumferential direction; the M first supporting cross beams sequentially pass through the support ringing in each stage of capacitor groups, both ends of the M first supporting cross beams are fixedly installed on both ends of the housing, and the M first supporting cross beams are uniformly distributed along the circumferential direction; charging resistors and switch trigger resistors are respectively installed on the M first supporting cross beams; and each gas switch is installed between each two stages of capacitor groups to form a group of breakdown units, and each group of breakdown units is connected in series.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to a coaxial Marx generator. Background technique [0002] Pulse power technology is an electrophysical technology that stores energy at a lower power, then compresses the energy in pulses, and releases high-power, short-pulse electromagnetic energy to a specific load. The Marx generator is a device that can obtain high-voltage pulses with amplitudes from hundreds of kilovolts to several megavolts and durations from hundreds of nanoseconds to several microseconds. The most commonly used equipment for conversion. [0003] The basic working principle of the Marx generator is that the high-voltage DC power supply charges the capacitor in parallel through the resistor, and then triggers the switch to break down, so that the capacitor is discharged in series to obtain a high-amplitude voltage pulse. The principle circuit of the Marx generator commonly used in pulse powe...

Problems solved by technology

The first type of Marx generator is suitable for the case where the energy storage capacity is small. The second type of Marx generator has a complex structure and is not compact enough, which increases the inductance of the discharge circuit.
