PSpice model simulation of electric exploding opening switch

Electric exploding opening switch(EEOS) is widely used in the inductive energy storage system, which has the features of simple structure, low cost, and strong ability of cutoff. Firstly the process of electric exploding wire was introduced. Its essence is a rapidly increased resistance, using its high impedance to achieve cutoff. Then a PSpice model, which simulated the resistor of the electric exploding opening switch, was created. A set of electric exploding opening switch experiments were designed. After that, the PSpice model simulation results were compared with the experimental results. The exploding moment and the voltage of the model were relatively close to the experimental results. The result shows that the model is reasonable. Finally, the deviation and limitation of this method were analyzed.
