Explosive-driven ferroelectric generator

An explosive-driven ferroelectric generator (EDFEG, explosively pumped ferroelectric generator, EPFEG, or FEG) is a compact pulsed power generator, a device used for generation of short high-voltage high-current pulse. The energies available are fairly low, in the range of single joules, the voltages range in tens of kilovolts to over 100 kV, and the powers range in hundreds of kilowatts to megawatts.[1] They are suitable for delivering high voltage pulses to high-impedance loads and can directly drive radiating circuits.
