HL-2A装置辅助加热高压电源控制系统的设计与实现

Design and realization of the control system of the auxiliary heating high-voltage power supply on HL-2A

研制了HL-2A装置LHCD和ECRH系统使用的高压电源,其电源拓扑分别为晶闸管交流调压型和星点控制型高压电源,通过高压脉冲调制器给LHCD和ECRH系统供电,采用了波头补偿、前馈和反馈相结合的控制方法,弥补了电源拓扑本身固有的瞬态特性不足和发电机输出的不稳定性,使电源输出电压输出平顶的稳定度优于1%。介绍了高压电源的主回路结构,对高压电源的控制进行了论述,同时给出了实验结果。

The AC regulated high-voltage power supply and the neutral point control high-voltage power supply are designed for LHCD and ECRH.The high-voltage pulse modulators are used in these power supplies.The wave head compensation,the feed forward control and the feedback control methods are adopted to compensate the dynamic characteristic fault of the power supply and the output voltage instability of the generators.The stability of output voltage is better than 1%.The main circuit and the control system are described.Good controlling properties and reliable protective properties of the control system are proven by the experiment results.
