摘要:
HT 7U全超导Tokamak核聚变实验装置等离子体环,在垂直位移方向上有着固有的不稳定性 .为了实现垂直位移方向上的稳定,给主动控制线圈供电的功率放大器,其响应速度必须具有快速性 .根据实验装置对放大器的参数要求,提出一种基于三态离散脉冲调制DPM模式 .它不但可以实现对给定电流或电压的跟踪,而且可以限制和降低开关频率的功能 .为满足实现负载大电流的要求,采用多模块并联技术,并进行数学建模分析 .最后,用小功率的台面实验加以证明
Abstract:
Plasma ring in HT 7U Tokamak as a test facility of fully superconducting nuclear fusion has its inherent instability. For realizing the stability in vertical displacement, the power amplifier must be fast in response for feeding active control coils. In terms of parameter requirement of amplifier,the authors suggest here to adopt a pattern based on three state discrete pulse modulation, by which not only the tracking of given current of voltage can be realized but also the switching frequency can be restricted and the fluctuation of output current can be lowered. For satifying the requcrement of loading high current, the technique of multiple module paralleling is adopted and the mathematical modeling and analysis of paralleling pattern are carried out. The scheme is proved finally by small power mesa test.
