Design and Parameter Analysis for Explosive-Driven Demagnetization Pulsed Power Source

We design a pulsed power source based on the technique for explosive-driven demagnetization. The physical process and geometry structure of this power source are described in detail and several formulae are deduced to predict some important properties of the power source. With a Ф 40mm×20mm×10mm cylindrical magnet, the maximum output voltage and current reaches 125.5V and 862.9A, respectively. The rise time of the front edge of the output voltage is about 264ns. On the 0.05Ω simulative load, the net power is 37kW.
