Abstract: In this work, based on the traditional pulse generators, we present an electromagnetic induction generator driven by explosion as a new technology of electromagnetic pulse generator. Having described the working process of the generator, we simulated and calculated the shock process of the explosion. Furthermore, we established the model for the working circuit of the generator with initial voltage and static magnetic, obtaining the calculation method of the induced voltage. An experimental generator with initial static magnetic provided by permanent magnet was designed, and the generators respectively fitted with two different explosives were tested. The experimental results show that the generator driven by higher detonation velocity of explosive can produce higher peak and shorter rise time voltage pulse, which are found to be a little lower than the calculation results due to the simplification in theoretical calculation of the magnetic field of the core and the velocity of shock wave.
