Abstract

The invention discloses a flat low-inductance and high-voltage capacitor which is characterized by comprising a main capacitor body, wherein the main capacitor body is arranged in a sealed shell; and the main capacitor body is composed of a plurality of layers of pole plates, insulating films are respectively arranged every two adjacent pole plates, and poles of the main capacitor body are respectively led out from the upper part and the lower part of the sealed shell. According to the invention, the main capacitor body is directly fastened by the high-strength insulating sealed shell to form an integrated structure, so that the integrated structure of the capacitor is more compact, and an inductor of the capacitor can be made smaller. The inductor of the capacitor is not larger than 17nH, and the withstand voltage can be up to 500kV under the action of pulse with the half width of 500ns and can be up to over 800kV under the action of pulse with the half width of 35ns. The flat low-inductance and high-voltage capacitor can be used for sharpening the pulse of a bounded-wave simulator with the output pulse front edge of 2.3+ / -0.5ns and the amplitude value of 600kV.

Description

technical field [0001] The invention belongs to a high-voltage energy storage device, in particular to a high-voltage pulse capacitor suitable for steepening the leading edge of an output pulse in the fast pulse voltage generation stage. Background technique [0002] In the field of electromagnetic pulse environment simulation technology, the simulator is usually required to generate a double-exponential pulse waveform with a fast rising leading edge and a slow falling trailing edge. The traditional fast Marx generator directly discharges the pure resistive antenna load, which can well meet the requirements of the slow-falling trailing edge double-exponential wave. However, for the Marx generator with high voltage and large energy storage, due to the limitation of the inherent inductance brought by the capacitor, gas switch and structural size, it is difficult to realize the fast leading edge output of the pulse waveform. Therefore, a low-inductance capacitor is required to...
