- Pulse power circuit is made simply because switching signal of PFN circuit is made by only external trigger signal after CCPS command voltage charging.
CCPS(Capacitor Charging Power Supply) can be used as an charging power supply of a pulse modulator which is a power of RF amplifier of linear accelerator at Pohang Linear Accelerator. The pulse voltage of this modulator requires high-precision stability at plat top. The high-precision power for 4th generation PAL-XFEL facility is known for requiring the stability of output voltage(≤ 50 ppm) and high efficiency >90%. The smart CCPS, as an ultra stable charging power supply, satisfies all this specification, and can control charging of each pulse unit.
