摘要: 介绍了一种输出脉冲峰值功率在GW量级,脉宽约6 ns,重复频率1~300 Hz可调的加速器的初级能源系统的设计与实验研究。它的初级能源由商用三相电源供能,利用硅堆整流,并通过固体开关及继电器等装置控制来实现对Tesla变压器初级线圈的重复谐振充电。实验表明该装置运行稳定,通过变压器升压之后可在120 W负载端得到300 kV的重复高电压脉冲。同时,该回路还利用了晶闸管拥有的自关断特性实现了能量的回收,提高了装置的能量利用率。Abstract: This paper introduces the design and experimental study of the primary energy source of an accelerator which can produce high power pulses (up to GW level) of duration about 6 ns, and repetition rate controllable from 1 to 300 Hz. The primary energy source is powered by a commercial three-phase AC power supply, rectified by semiconductor devices, and resonantly charges the Tesla transformer controlled by solid switches and relays. The experimental results indicate that this system can produce repetitive high voltage pulses (up to 300 kV) at a 120 Ω load through the Tesla transformer and operates stably. Meanwhile, this source takes the advantage of self-shutoff of the thyristors to realize energy recovery.
