  • Integration of the pulse power source into a bounded wave electromagnetic pulse simulator.
  • Characterization of the simulator's output pulse parameters (peak voltage, risetime, pulse width).

    • Main Results:

    • The developed pulse power source achieved an output peak voltage of 74.5 kV.
    • The source exhibited a fast risetime of 2.05 ns and a pulse width of 22 ns.
    • The all solid-state electromagnetic pulse simulator generated an electromagnetic environment with a 2.2 ns risetime and 23.5 ns pulse width.

    Conclusions:

    • The all solid-state pulsed power source is a viable component for EMP simulators.
    • The developed simulator can produce controlled EMP environments for studying electronic system vulnerability.
    • This technology aids in understanding EMP effects and developing effective protection strategies.
