在J-TEXT托卡马克装置上安装了一套容器内鞍形线圈。为进一步研究利用静态和动态共振磁微扰控制撕裂模和驱动等离子体旋转提供了参考。鞍形线圈将在1-5 kHz的频率范围内由幅度高达10 kA的直流电或最大幅度高达5 kA的交流电供电。在直流模式下，采用两个反并联的6脉波晶闸管整流器，以获得双向电流;在交流模式下，采用包括串联谐振逆变器的AC-DC-AC变换器，可以产生各种幅值和频率的电流。本文在定义电源需求的基础上，对电源系统的拓扑结构和控制策略进行了可行性分析，提出了电源系统的设计方案。最后给出了仿真和实验结果。
A set of in-vessel saddle coils has been installed on J-TEXT tokamak. They are proposed for further researches on controlling tearing modes and driving plasma rotation by static and dynamic resonant magnetic perturbations (RMPs). The saddle coils will be energized by DC with the amplitude up to 10 kA, or AC with maximum amplitude up to 5 kA within the frequency range of 1–5 kHz. At DC mode two antiparallel 6-pulse phase thyristor rectifiers are chosen to obtain bidirectional current, while at AC mode an AC–DC–AC converter including a series resonant inverter can generate current of various amplitudes and frequencies. The paper presents the design of the power supply system, based on the definition of the power supply requirements and the feasibility of implementation of the topology and control strategy. Some simulation and experimental results are given in the end.
