Drivers of small and medium scale electromagnetic pulse simulator based on Marx generator

In order to meet the requirements of anti EMP performance test of the difference size effect test compounds, and to generate the simulated EMP environments with more comprehensive coverage and more ideal waveform, in the paper, the basic composition and working principle of the EMP-simulator diver with one-stage pulse sharpening and based on the Marx generator are introduced. According to the actual experiences of design and debugging of this kind of devices, some problems that may be encountered when using the ideal principle to design these drivers are analyzed, and some targeted solutions are provided. In addition, some drivers for the small-and-middle scale EMP simulator with rated output voltage of 100-600 kV are developed. With the development of super compact Marx generator, compact flat-form film capacitor and low inductance output switch, the optimization of the connection structure, and the selection of reasonable parameters, these drivers connected with the load of 120-180 Ω can produce the ideal double exponential waveforms with the rise time of 1.2-2.7 ns and the half width of 32-41 ns.
