Problems solved by technology

The use of pulse transformers can generate bipolar high-voltage pulses, but it requires a large number of auxiliary equipment to realize, making the entire structure complex and cost increased
When the Marx generator is used to generate fast-leading bipolar high-voltage pulses, the synchronization delay is very long (at least more than a hundred nanoseconds, and the jitter is also more than ten nanoseconds), and synchronization acquisition cannot be achieved

Abstract

The invention relates to a nanosecond leading-edge bipolar high voltage pulse generation device. The device can generate nanosecond leading-edge bipolar high voltage pulse through a mode that a capacitor directly discharges electricity and has the advantages of little accessory equipment and simple structure; furthermore, synchronous time delay of the bipolar high voltage pulse is a nanosecond level. The device mainly comprises an insulation cavity, a positive polarity energy storage capacitor, a negative polarity energy storage capacitor, a three-electrode switch inflation air faucet and a cavity inflation air faucet, wherein the positive polarity energy storage capacitor and the negative polarity energy storage capacitor are arranged in the insulation cavity, the three-electrode switch inflation air faucet is used for inflating and deflating in a three-electrode switch, and the cavity inflation air faucet is used for inflating the insulation cavity. By means of reducing air pressureof the three-electrode switch, gas gap conduction is achieved; thus, negative polarity high voltage pulse and positive polarity high voltage pulse are respectively generated.

Description

technical field [0001] The invention relates to a pulse generating device, in particular to a nanosecond leading edge bipolar high-voltage pulse generating device. Background technique [0002] Fast-leading high-voltage pulses can be used to drive loads directly, or as triggers for power systems that output higher voltage pulses. It plays an increasingly important role in emerging technology industries (environmental protection, radiation disinfection, radiation etching) and high-tech weapons (intense pulse laser, high-power microwave, electromagnetic pulse weapons). [0003] In order to obtain bipolar high-voltage pulses, the current existing method is to use a Marx generator and a pulse transformer to generate them. The bipolar high-voltage pulse can be generated by means of a pulse transformer, but it needs a large number of auxiliary equipment to realize it, which makes the whole structure complicated and the cost increased. When the Marx generator is used to generate ...
