Abstract
To study the damage and protection mechanism of an electromagnetic pulse to an electronic system, an all solid-state high-voltage pulse power with photoconductive semiconductor switch is developed, which is a component of the bounded wave electromagnetic pulse simulator. The output peak voltage of the prepared all solid-state pulsed power source was 74.5 kV, the risetime was 2.05 ns, and the pulse width was 22 ns. In addition, the peak voltage of the output pulse of the all solid-state pulsed power source could be regulated. The all solid-state electromagnetic pulse simulator developed in this work can generate an electromagnetic environment with a risetime of 2.2 ns and a pulse width of 23.5 ns.
