Abstract:

The design and implementation of pulse power control system for magnetic confinement plasma, using the field programmable gate array (FPGA) technology are presented. Virtual instrument technology, embedded control technology, serial communication technology, and optical isolation technology are used to improve the system's anti-jamming performance and programmability, and to realize logic interlock, parameter setting and remote monitoring among multiple pulse power modules. The control system is specifically composed of the upper computer interface programmed by Labview (Laboratory Virtual Instrument Engineering Workbench), lower-level machine programmed by Verilog HDL (Hardware Description Language) and dedicated photoelectric isolation conversion circuit, which is used to implement timing control of multiple pulse power supply and discharge. The experiment proves that the system is stable and has good performance under complex electromagnetic environment.
