| Abstract |
The capacitor-charging power supplies (CCPSs) for the klystron modulators have been developed from 2002 in the SuperKEKB injector linac. The specifications are that the output voltage is 43kV, the charging power is 30kJ/s, and the output voltage stability is 0.2%p-p. Being used in the old facility, their sizes are restricted in 480mm x 680 mm x 760mm. After various modifications, the 13 CCPSs in the linac have been operated with no fault since last October. The present status of the CCPSs, including the outlines, specifications, and the modifications against the faults, are described.
