Problems solved by technology

The existing pulse power supply data acquisition system uses the PXI bus to connect dozens or even hundreds of current sensors of power modules. The connection is complicated, the volume is huge, and the collected data cannot be viewed in real time. The received data is imported into professional analysis software for data analysis, so it is impossible to find problems in the operation process of pulse power supply through voltage and current data in time
Therefore, the existing pulse power supply data acquisition system is only suitable for single discharge conditions, and there are great hidden dangers in the continuous discharge conditions of pulse power supplies

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a data acquisition system for high-power pulse power supply. Background technique [0002] The high-power pulse power supply is composed of high-voltage high-frequency charger, pulse forming network, measurement and control unit, safety discharge and protection components and other parts. The pulse shaping network is the core unit of the pulse power supply, and generally includes multiple pulse power supply modules. The pulse power supply module is composed of pulse capacitors, high-power thyristors, high-voltage silicon stacks, wave-modulating inductors and other key components and peripheral devices. The pulse power supply can charge and store energy to the pulse capacitor of the power module through the charger, and then release the energy to the pulse shaping network through the high-power thyristor of the power module to form a large pulse current for the load. ...
