Compact 700-KV Erected Pulse Forming Network for HPM Applications (Postprint)

摘要

Increased interest in deployable High Power Microwave systems has led to demand for compact pulsed power drivers for HPM loads, such as magnetrons, that are sensitive to pulse shape, APELC has developed a 600-J, erected pulsed-forming network capable of delivering a 200-ns square pulse to RPM loads. The generator consists of eight, erected pulse-forming sections charged from a common supply. The resonant sections combine to produce a Fourier-approximated square pulse at the load. Pulse characteristics include a FWHM of 200-ns, rise time of 25 ns, and a decay time of 60 ns. The generator is housed in an 18' diameter by 60' long pressure vessel and uses only compressed dry air for insulation. The generator is capable of 50-Hz pulse repetition frequency and features soft-failure modes for continued operation in the event of component failure.
