Plasma position control system in HL-1M tokamak

Abstract

The HL-1M tokamak is the modification device of HL-1. In this paper, the consideration for plasma equilibrium and the design of the coil, power supply and control circuits for the plasma position control system in HL-1M tokamak are presented, four-quadrant thyristor converter (FQTC) with the circulating current for the power supply of the fast vertical field (FF) coils and the control circuits are described, the commissioning results for the FF power supply with a dummy coil are given.
