  The stability of the modulator high voltage output pulse is the important target for the klystron. The stability of the BEPCII modulator is demanded less than 0.15%. To achieve this target, we use thyristor voltage regulator having feedback function to stabilize the DC high voltage of the modulator and the De-Qing circuit to stabilize the charging voltage. This paper describe the modulator stability system and the stabilization measurement .

  The China Spallation Neutron Source (CSNS) Rapid Cycling Synchrotron(RCS) injection system needs three pulsed power supplies to drive twelve bump magnets. The current of the three pulsed power supplies are 11813A,9706A,8205A. Two of the pulsed power supplies work in controlled method at falling edge. This paper introduces the design of the three pulsed power supplies, the circuit simulation results and the demonstration of power supplies stability.
