Abstract :
A SPICE macro model for a triggered vacuum gap, a sprytron, intended for use in rapid discharge circuits such as Exploding Bridge Wire (EBW) applications, is presented. Power MOSFETs in the avalanche mode are utilized as the active switching elements in the model. The macro model is compared for accuracy in predicting the time dependent switching current, switch resistance and voltage drop across the switch using several test circuits. Techniques for extracting model parameters are discussed
