摘　　要：　采用软开关恒流充电技术,研制了一台40kV/20kW开关型脉冲成形网络(PFN)充电高压电源装置,该装置在重复频率范围、PFN电容容量较大变动时,都能达到高的稳定性,并具有体积小、效率高、可并联运行的特点,可用于环型加速器注入引出、直线加速器、雷达发射等领域。介绍了该装置的研制及带PFN负载的实验状况。A 40 kV/20 kW switching-mode pulse forming network (PFN) charging power supply was developed by constant-current, series-resonant and soft-switching techniques. High pulse to pulse repeatability was achieved even under the condition of high repetition rate and small PFN capacitance. The power supply also featured in high efficiency, small size and the ability of being used in parallel mode. The techniques can be applied to injection/extraction system of circular accelerators, klystron modulators in Linasc and radar transmission. Design of the power supply and PFN charging and discharging experiments are presented in the paper.
