Abstract – This paper presents a compact and portable high-voltage generator based on magneticcore
Tesla transformer for driving an UWB high power electromagnetic source. In order to optimize
the performance of the high-voltage generator, a novel open-loop cylindrical magnetic-core adopting
the quad-division lamination structure is proposed and manufactured. The designed high-voltage
generator using the proposed magnetic core has a battery-powered operation and compact size of 280
mm × 150 mm in length and diameter, respectively. The high-voltage generator can produce a voltage
pulse waveform with peak amplitude of 450 kV, a rise time of 1.5 ns, and pulse duration of 2.5 ns at
the 800 V input voltage.
