Adjustable Width Solid-State PFN Pulse Generation Using a Recyclable Energy Circuit
Pulsed power technology, with its trend toward compactness, flexibility, energy sustain-ability and adjust-ability, is the cornerstone of high-power microwave (HPM) system. Exploring and improving the generation of adjustable rectangular wave pulses is the key to this technology. This article presents an recyclable and adjustable pulsewidth solid-state Blumlein pulse-forming network (BPFN) pulse generation which consists a BPFN circuit, a recyclable circuit, and a chopper switch. The recyclable circuit is utilized to recycle oscillation energy generated by chopper switch and is ready to be released for further utilization. By controlling the switch-on time of chopper switch after the main switch switched on, the pulsewidth is able to be adjusted. The pulsewidth of output wave of our proposed circuit can be adjusted flexibly, energy recycle efficiency is up to 97%, and its wave process is verified by simulation. In addition, the pulse power evaluation circuit board is built to demonstrate its performance. The experimental results show that the pulsewidth can be adjusted from 0.3 to $1.2~\mu $ s with the output voltage of 800 V. The oscillation energy produced by chopping can be recovered, with recovery efficiencies of 2.91%, 8.03%, 26.69%, and 43.08% corresponding to pulse widths of 1.2, 1, and $0.4~\mu $ s, and fully recovery, respectively.
