摘　　要：PREF装置是中国科学院新疆理化技术研究所与近代物理研究所联合设计建造的10~60 MeV质子同步加速器,属于国内唯一的位移损伤效应模拟试验专用装置。针对该装置的扫描磁铁电源输出电流频率200 Hz、跟踪误差小于≤±5×10^(-3)的技术要求,采用三组H桥串联拓扑方案,通过移相控制,基于脉宽调制实现技术要求。经仿真与测试结果表明:电源能够输出峰-峰值为±420 A,幅值与频率均连续可调的高精度三角波电流,满足工程应用要求。The PREF device is a 10-60 MeV proton synchrotron jointly designed and built by Xinjiang Institute of Physics and Chemistry,Chinese Academy of Sciences and Institute of Modern Physics,Chinese Academy of Sciences,which is the only dedicated device for displacement damage effect simulation test in China.For the technical requirements—the output current frequency of the scanning magnet power supply is 200 Hz,and the tracking error is less than≤±5×10^(-3)—of the device,three stage H-bridge series topology schemes are adopted,and the technical requirements are realized based on pulse width modulation through phase shift control.Simulation and test results show that the power supply can output high precision triangular wave current with peak-to-peak value of±420 A,continuously adjustable amplitude and frequency to meet the requirements of engineering applications.
