摘　　要：介绍了HL-2A装置电子回旋系统主高压电源的研制。用星点控制技术实现了高压直流平台输出电压的调节;用TM-703FB大功率调制管为核心的高压调制技术实现了高压电源输出电压的快速升降及电源的快速保护。用前馈补偿和反馈控制技术实现了输出电压波纹小于1%。电源输出总体指标为?60kV/(25A×4)/1s,满足了ECRH系统的要求。The main high voltage power supply of the ECRH system on HL-2A tokamak is described. The output voltage is managed by adopting the star-point control technique, and the fast rising and falling of the output voltage can be realized by implementing the high-voltage modulation technology based on TM-703FB modulator, by which the fast protection of this system can be performed. The output-voltage ripple in this system is less than 1% due to the feed-forward compensation and feedback control technologies, the output parameters, --60kV/（25A×4）/1s, can meet the requirements of the ECRH system on HL-2A tokamak experiments.
