| 摘 要： | 为了提高EAST装置中共振磁扰动(RMP)线圈电源的输出电压、电流响应速度和输出特性，对共振磁扰动线圈电源的响应时间延迟进行了分析和优化处理。详细分析了对称规则采样和单极性倍频PWM调制过程所产生的时间延迟，针对该部分时间延迟提出了多次采样延时数据更新方法，对逆变电源控制器进行优化和改进。实验结果表明，采用该方法后电源输出响应时间延迟从206μs减小为70μs，可以满足EAST实验的需求。

| Abstract: | In order to improve response speed and output characteristics of resonant magnetic perturbations (RMP) coil power supply of EAST tokamak, the response time delay is analyzed and optimized. Time delay that is caused by symmetrical rules sampling and single polarity PWM is amply analyzed and quantitatively determined. And multiple sampling & tardive updating is proposed to improve inverter response delay. The experimental data demonstrates that response time delay is decreased from 206μs to 70μs by the method, which meets the requirement of EAST experiments. |
