In this paper, nanosecond pulse power generators and their applications are reviewed. Generally, in pulse generating circuits, the Drift-Steps-Recovery diodes (DSRDs) play an important role as the opening switches. The simulation of a pulse generating circuit using (DSRDs) is done by using MATLAB software. A generating circuit of unipolar and then bipolar pulses are simulated and discussed. Whereas in all simulations we focus on a pulse generator circuit because of its important application.
