Multichannel timing sequence trigger

Abstract

A multichannel timing sequence trigger comprises a discharging trigger (1), an A-channel LD laser light source optical splitter (2), B-channel light beam splitting devices (3), LD laser light source receivers (4) and time delay modules (5). The input end of the discharging trigger (1) is connected with a 5V direct-current power supply. The output end of the discharging trigger (1) is connected with the A-channel LD laser light source optical splitter (2). The A-channel LD laser light source optical splitter (2) divides the input electrical signals into A-channel optical signals. The A-channel optical signals are connected with the A B-channel light beam splitting devices (3) through A-channel optical fibers. The A B-channel light beam splitting devices altogether output A*B channels of optical signals. The A*B channels of optical signals are connected with A*B LD laser light source receivers (4) through optical fibers. The output of the A*B LD laser light source receivers (4) is connected with the A*B time delay modules (5). The output of the A*B time delay modules (5) are the A*B channels of time delay trigger signals with different time delays.

Description

Technical field [0001] The invention relates to a multi-path sequence trigger, in particular to a sequence discharge trigger of a multi-module pulse power supply system in the field of pulse power. Background technique [0002] Pulse power source is a necessary condition for research and development in the field of pulse power. The development level of pulse power technology is limited by the development level of pulse power sources. In order to break through the limitation of the output capability of a single pulse power source, the sequential discharge of multiple modules is an effective solution. The pulse power source composed of multiple modules needs to trigger control of each component module according to a certain timing according to the requirements, and obtain the final output waveform that meets the requirements by combining the single output of each module in series or parallel. Therefore, the high-precision multi-channel timing trigger controller is one of the key ...

[0003] Patent 201210549544.4 introduces a liquid-phase pulse discharge system based on multi-channel switch delay output. This patent generates a trigger pulse train with a certain time interval through a sequential pulse generator, and performs photoelectric isolation and amplification on the three trigger pulses before using For the triggering of switches in the pulse source, this method is suitable when the number of trigger channels is small. When the number of trigger channels increases, the performance of the sequential trigger is usually increased to output multiple trigger signals with different delays. The development of the sequential trigger The ability requirements are high. At the same time, multiple trigger signals with different delays use separate transmission paths. When there are many channels and long distances, the system cost is high.
