Design of Anode Power Supply of High Power RF Amplifier for Ion Cyclotron Resonance Heating System in EAST

摘要: 离子回旋共振加热是EAST超导托卡马克核聚变实验中重要的辅助加热手段。高性能的高功率射频放大器阳极电源对整个加热系统的稳定运行起重要作用。本工作设计了基于脉冲阶梯调制（PSM）技术的阳极电源及其控制保护系统，通过采集电源的实验数据对电源的设计进行了验证。实验结果证明，本阳极电源的设计和参数选择均是合理正确的，电源的开通和关断以及控制保护的数据指标完全达到设计要求。

Abstract: Ion cyclotron resonance heating (ICRH) is a necessary auxiliary heating method in EAST Tokomak nuclear fusion experiment. It is very important to develop a qualified anode power supply for the operation of ICRH system. The anode power supply based on pulse step modulation (PSM) technology was designed. The experimental data show that the design of the anode power supply is reasonable.
