In this paper, we numerically characterized a novel, compact nanosecond high voltage pulse generator. The device was developed for innovative medical treatments and makes use of a combination of microstrip line technology and microchip laser triggered photoconductive semiconductor switches (PCSS). Two different modeling methodologies were considered. First, a full wave finite difference time domain (FDTD) analysis was completed. The second approach proposed a circuit model of the generator that was solved using SPICE simulations. Further, the FDTD analysis led to the development of an appropriate model for PCSS. The results showed good agreement between the two modeling methodologies and preliminary experimental measurements performed on a generator prototype. The presented work showed the utility of these modeling tools for the development of innovative devices.
