摘　　要：A new 20 kV high voltage system has been designed,developed and operated in CSRm cooler[1],in order to satisfy requirements of pulsed electron cooling experiments[2].Series of FuG high voltage power supplies were used,including a 20 kV main power supply,two 3.5 kV DC power supplies for the anode and suppressor,a3.5 kV power supply for the grid,a 3.5 kV power supply with the maximum current of 3.0 A for the collector and a 20 V power supply for the filament.The sketch of the power supply system is shown in Fig.1 and the main parameters of all power supplies are listed in Table 1.The residual ripple of the main power supply is around 105(max.p-p value).A LAN interface was built in the main power supply,and other modules were communicated with the main power supply by optical fiber.A interlock system was used for the grid and anode power supplies,therefore the extracted electron beam can be cutoff quickly(<10 ms)while the leakage current of the main power supply is over threshold.
