摘要
A feedback control system is needed to restrain plasma vertical displacement in EAST (Experimental Advanced Superconducting Tokamak). A fast control power supply excites active feedback coils, which produces a magnetic field to control the plasma's displacement. With the development of EAST, now demands on the now fast control power supply have led to an enhanced ability of fast response and output current, as well as new control mode. The structure of cascaded and paralleled H-bridges can meet the demand of extended capacity, and digital control can realize current and voltage control mode. The validity of the proposed scheme is confirmed by experiments.
