A nonlinear lumped element transmission line (NLETL) that comprises a LC-ladder network where either the capacitors or inductors are nonlinear can be used to convert an input rectangular pulse to a series of RF pulses at the output. This article describes the implementation and demonstration of a high voltage nonlinear hybrid line (NLHL) where both the line components (inductor and capacitors) are...
A nonlinear lumped element transmission line (NLETL) that consists of a nonlinear LC ladder network whose capacitors are nonlinear and inductors are linear can be used to produce oscillating pulses. This article describes the implementation of an oscillating pulse generator based on such high voltage nonlinear capacitive lines (NLCL) using commercial-off-the-shelf (COTS) components. Instead of using...
A Marx generator is a well-known type of electrical circuit first described by Erwin Otto Marx in 1924. It has been utilized in numerous applications in pulsed power with resistive or capacitive loads. To-date the vast majority of research on Marx generators designed to drive capacitive loads relied on experimentation and circuit-level modeling to guide their designs. In this paper we describe how...
The UNM educational reltron is driven by a 2 stage bipolar 396 J Marx generator capable of generating a maximum of 120 kV. The output voltage pulse has a rise time of less than 0.25 ??s and a variable pulse width of 1-4 ??s. The pulse width is controlled by a crowbar switch that shunts current away from the load. An analytic model of the Marx generator's charging and discharging is developed. The...
Summary form only given. The relativistic magnetron provides a low-impedance (10-20 U) load that inherently needs matching to a low-impedance pulsed-power supply (gigawatt or greater power) to operate with maximum efficiency. One of the most common and reliable pulsed-power drivers used to accomplish this is a Marx generator. The University of New Mexico previously used a modified Pulseradreg 110...
