摘　　要：介绍了合肥同步辐射光源速调管调制器改造项目 .在新的设计中采用了开关型恒流PFN充电电源 ,计算了充电参数 ,建立了主放电回路的仿真模型 ,重点分析了电路中反向电压问题 ,依据仿真结果及分析设计了反向保护电路 .给出了运行中的主要波形 .最后介绍了新的调制器控制系统 .The upgrading project of the HLS (Hefei Light Source) klystron modulators was firstly introduced. Constant-current, switch-mode,PFN charging power supplies were adopted in the new design. Charging parameters were calculated. Simulation model of main discharging circuit was established. An emphasis of analysis was put on the reversal voltage problem. A protection circuit was designed based on the simulation results and reversal voltage study. Major waveforms measured from daily operation were presented. Finally new control system of the modulators was described.
