EAST等离子体垂直不稳定位移主动反馈控制

摘要

在EAST装置上通过设置反馈控制系统来抑制等离子体的垂直位移。快控电源对主动反馈线圈励磁，产生磁场抑制等离子体偏移。为满足等离子体位移快控电源大电流快速响应要求，采用多组变流器并联运行。实验运行结果说明主动反馈控制系统设计方案合理，达到了设计要求。%The feedback control system is restrained plasma vertical displacement on EAST. Fast control power supply excites active feedback coils, which produces magnetic field to control plasma’s displacement. To meet the requirement of large current and fast response, multi-inverters in parallel is presented. The validity of proposed scheme has been confirmed by experiments, the active feedback system can reach design demand.
