Outline of lecture

This lecture provides the generation, diagnostics, and applications of high power electrical pulses. A wide range of pulsed power technology will be discussed, including fundamental as well as advanced concept. Topics covered are high-voltage generators, energy storage devices and circuits, high power switches, pulse forming networks, pulse forming lines, magnetic pulse compression circuits, and the electrical and optical diagnostics of pulsed power systems. Applications of pulsed power technology for lasers, non-thermal plasmas, and environmental and medical applications will be discussed.
Students are required to do numerical simulations to understand a behavior of pulsed power circuits and breakdown phenomena, and to complete a report for a given project.

Purpose of lecture

Upon completion of this lecture students should be able to design pulsed power circuits including switches, pulse forming networks/lines with discharge loads, using LTSpice circuit simulator and Scilab/Matlab software to solve various pulsed power circuits. They should also be able to measure pulsed large currents and high-voltages with appropriate methods of grounding and shielding, and understand the applications of pulsed power technology.
