Abstract

The invention discloses a composite switch based on waveform control. The composite switch includes a composite switch unit, a waveform acquisition unit and an intelligent control unit; the output terminal of the waveform acquisition unit is connected with the input terminal of the intelligent control unit, and the output terminal of the intelligent control unit The end is connected with the control end of the composite switch unit. The invention is mainly applied to the failure protection of controllable nuclear fusion plasma rupture. It has the characteristics of high switching accuracy, fast response speed, identifiable waveform and reliable isolation. It can conduct the rupture protection circuit in time to realize rupture protection, effectively improving Device security.

Description

technical field [0001] The invention belongs to the technical field of controllable nuclear fusion switches, and more specifically relates to a composite switch based on waveform control. Background technique [0002] Tokamak uses a magnetic field to confine high-temperature plasma in a circular vacuum chamber for circular motion, forming a stable plasma current, but there is a risk of plasma rupture, and the loss of confinement of high-energy plasma will cause serious impact damage to the internal components of the device . Breakage failure protection can be achieved by quickly turning on the inductance coil-based breakage protection circuit with a specially designed switch that can recognize the high voltage pulses provided by the tokamak power supply system to establish the plasma current and the formation of The high-voltage pulse of the tokamak should be reliably isolated from the rupture protection circuit, and the high-voltage pulse provided by the tokamak power syst...
