| Abstract: | 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. |
