A Compact Battery-Powered 500kV Pulse Generator for UWB Radiation

Many applications involving compact and portable systems for generating high power electromagnetic fields depend on the enabling pulsed high voltage technology. This paper describes a system that is able to produce nanosecond rise time pulses with voltage exceeding 500 kV. It is based on a pulsed resonant Tesla transformer, and requires also a pulse forming line, a fast spark-gap output switch, and an antenna. After dealing with the system design and various measurement results, the paper suggests means by which improvements to the existing system could be made.
