Flexible Pulsed Power Generator for High Power Microwave Applications
Abstract
This proposal requests to purchase an inductive adder (IA), which is a high voltage pulsedpower modulator capable of achieving fast rise times while maintaining the advantages of an allsolid-state system such as highly controllable waveforms, repetition frequency, and efficiency.This device will be able to output 20-24 kV into a 25 or 50 load with an adjustable pulsewidth of 30-100 ns, output rise time of 12 ns or less, and a continuous pulse repetition frequencyof at least 1 kHz and up to 6 kHz for bursts of 100 pulses. This device will greatly enable currenthigh power microwaves (HPM) and directed energy (DE) research by the BioElectrics andElectroPhysics (BEEP) Laboratory at Purdue University, while also providing a flexible highvoltage, high repetition rate pulse generator for expanding this research in the future. The BEEPLaboratory current has three pulse generators with pulse durations of 10 ns, 60 ns, and 300 ns thatcan drive biological loads with impedances of approximately 10 with repetition rates of 1 Hzand voltages up to approximately 30 kV. While these pulse generators provide some prototypingcapability, they do not encompass the typical 50 impedances of HPM and DE systems. Theproposed IA will fill this operational gap.
