Abstract:

AC power control system designed for dynamic resonant magnetic perturbation (DRMP) on J-TEXT tokamak was introduced. It mainly focuses on analysis, design and optimization of an inverter control unit run in field programmable gate array (FPGA), based on all-digital phase-locked loop (ADPLL).Test results and performance of the system in the DRMP experiments are given. The results show that this power control system can fulfill the output frequency and phase control demand for the DRMP experiment and offer a reliable and stable operation.

Key words: Dynamic , resonant , magnetic , perturbation , (DRMP); , AC , power , system; , Control , system; All-digital phase-locked loop (ADPLL), Field programmable gate array (FPGA)
