Abstract

Recent experimental studies on plasma armatures at the Applied Physical Electronics Research Center at the University of Texas at Arlington require the delivery of a single high-current pulse. The railgun diagnostic program now in progress requires a ramping current waveform with a continuously positive di/dt until peak current is delivered approximately 1 ms after circuit closure. This pulse forming network (PFN) is designed to power blocked-bore plasma armature studies being conducted on a section of the THUNDERBOLT prototype, SUVAC. The PFN design has an operating voltage range from 300 to 1400 V and is capable of delivering peak currents up to 200 kA.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
