摘要：A compact high-voltage repetitive nanosecond pulse generator(HRNPG)was developed for studying the technology of repetitive nanosecond pulse technology and its related *** HRNPG mainly consists of a repetitive charging module,a Tesla transformer and a sharpening *** its voltage lower than 1 kV,the primary repetitive charging circuit comprises two fast thyristors as its low-voltage *** spiral Tesla transformer acts as the main step-up component,and its peak transformation ratio is designed to be more than 100.A self-breakdown spark switch,*** sharpening switch,is used to sharpen the output of the transformer and to generate nanosecond *** HRNPG prototype is capable of generating pulses of 100 kV in peak with rise time 30 ns and the maximum repetition rate of 500 Hz on a 6 k *** results show,without any magnetic core,the developed Tesla transformer prototype can easily output high voltage while keeping itself small in size and light in weight,which is of significance for the compactness and portability of the pulse *** N2-insulated spark switch operated well at voltage close to 100 kV and the repetition rate within several hundreds of hertz.
