A cost-effective power supply for static magnetic field coils used in fusion plasma experiments has been developed by application of an electric double layer capacitor (EDLC). A prototype EDLC power supply system was constructed in the form of a series LCR circuit. Coil current of 100 A with flat-top longer than 1 s was successfully supplied to an equilibrium field coil of a fusion plasma experimental apparatus by a single EDLC module with capacitance of 30 F. The present EDLC power supply has revealed sufficient performance for plasma confinement experiments whose discharge duration times are an order of several seconds.
通过应用双电层电容器（EDLC），开发出了一种用于聚变等离子体实验中静磁场线圈的高性价比电源。一个EDLC电源系统原型以串联LCR电路的形式构建而成。利用一个电容为30F的单个EDLC模块，成功地向聚变等离子体实验装置的平衡场线圈提供了100A的线圈电流，平顶时间超过1秒。目前的EDLC电源在放电持续时间为几秒量级的等离子体约束实验中已展现出足够的性能。
