HL-2A共振磁扰动线圈电源的方案设计与仿真

Conceptual design and simulation of HL-2A RMP coils power supply

介绍了共振磁扰动(RMP)电源的电路拓扑结构,基本元器件的选取,初步控制方案以及电路相关的计算与仿真。RMP线圈将由最大4k A的直流电流或者最大频率1k Hz最大4k A的交流正弦电流供电。通过选择合理的电源结构和控制方式,以实现响应速度快和电流纹波小的要求,并使RMP线圈电源满足ELM控制的需求,尽量降低对等离子体控制的不利影响。

The conceptual design and simulation of HL-2A resonant magnet perturbation（RMP） coils power supply are introduced, including its power supply topology, the selection of basic units and its control modes. The RMP coils will be energized by DC power supply with the amplitude up to 4k A, or AC power supply with maximum amplitude up to 4k A with adjustable frequency up to 1k Hz. Though choosing the sound power supply topology and its control modes, the RMP coils power supply can meet the requirements of both fast response and low current ripple to satisfy the ELM control and minimize adverse effects on plasma control as far as possible.
