Design and experiment of compact seed source for explosive magnetic flux compression generators

A compact seed source for explosive magnetic flux compression generators was developed, and its components, working principle, best output time sequence model were analyzed. An explosive-driven slide unit was designed for switching scheme, and its performance was tested at high voltage. The compact seed source is a system with Ф132 mm200 mm volume, 12.5 kg weight, 5 kV operating voltage, nearly 750 J storing energy, less than 30 s charging time, capable of delivering energy more than 600 J or current more than 5.4 kA into an flux compression generators load (42 H, 78 m) at static condition, coupling energy more than 550 J or current more than 5.2 kA at dynamic condition, time sequence control error less than 5 s, effect energy density more than 200 mJ/cm3, and transfer efficiency more than 75%.
