A Transmission Line Isolated Linear Transformer Driving Source

Abstract

The invention relates to a transmission line isolation type linear transformer drive source. The drive source comprises a switched capacitor primary energy module, an isolated transmission line and an induced voltage superposition module; the switched capacitor primary energy module comprises M-level primary energy boxes arranged in parallel, each level of primary energy N switch capacitor modules are connected in parallel in the box; all high-voltage gas switches in the N switch capacitor modules are triggered in parallel by one trigger signal synchronously; the induced voltage superposition module includes an M-level annular induction cavity, and the M-level annular induction cavity is arranged in series; each There are magnetic cores and N radial transmission lines evenly distributed along the circumference in the ring-shaped induction cavity; the invention solves the problem that the switch is placed in the existing LTD technology by isolating the switched capacitor primary energy module and the induced voltage superposition module. The problem of reduced breakdown performance and high maintenance work caused in the induction cavity also solves the problem of the inability to achieve voltage superposition in Thor-type devices.

Description

Technical field [0001] The invention belongs to the fields of pulse power technology and high voltage technology, and particularly relates to a transmission line isolation type linear transformer drive source. Background technique [0002] Using Linear Transformer Driver (LTD) to achieve high-power Z-pinch is an international frontier research field in recent years [1] . This is because compared to the traditional pulse power technology, LTD technology can output high-current high-voltage fast pulses through the principle of induction and superposition without any pulse compression section. It has the advantages of compact structure, modularization, high repetition frequency operation, adjustable output waveform and strong fault tolerance. [0003] The current LTD research is represented by the Russian Institute of High Current Electronics (HCEI) and the US Sandia Laboratory (SNL). China, France, and the UK are also conducting corresponding research at the same time. [0004] HCEI ...
