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 electromagnetic and optical diagnostics of pulsed power systems. Applications of pulsed power technology for lasers, non-thermal plasma, and environmental and medical applications will be discussed. Students are required to simulate typical pulsed power circuits and gas breakdown.
The students will comprehensively understand pulsed power technologies, which have been widely used in industry, through the generation, diagnostics, and applications of high power electrical pulses.
Upon completion of this lecture students should be able to design pulsed power circuits including high-power switches, pulse forming networks/lines with discharge loads, using LTSpice circuit simulator or MATLAB software to solve various pulsed power circuits and gas breakdown. They should also be able to choose appropriate methods of measuring, grounding and shielding techniques for pulsed large currents and high voltages, and understand the applications of pulsed power technology.
