Design of a real-time control system for pulse power supply in tokamak

A high-performance real-time control system is designed for magnet power supply in tokomak, which is based on LabVIEW RT and field programmable gate array (FPGA) techniques. According to the real-time control requirements of the magnetic power supply, a reflective memory card was used to realize real-time data transformation, and a real-time operation system is applied to ensure the reliability and determinism of the power supply system. Then NI DAQ 7813R data acquisition card was used to control thyristor converter. The experimental results of the real-time control system for the power supply are presented, which demonstrate that the control system meets the design requirement and has high-reliability and determinism.
