Abstract
A repeatable explosive-driven electrical pulse generator system includes an explosive propellant driver in which the chemical charge in a cartridge is exploded by impact of the driver's firing pin by the hammer of an actuator. The chemical energy released by the explosion drives a piston and piston rod within a cylinder of the driver from an initial retracted position to an extended position. Simultaneously, a high coercivity permanent magnet attached to the piston rod and disposed between the poles of a magnetic circuit in a slot of a ferromagnetic core is ejected from the magnetic circuit. Such rapid ejection causes rapid decrease in the flux flow in the magnetic circuit and generation of an electrical pulse in a coil coupled in the magnetic circuit. The restoring action of a reset spring and pneudraulic device compressed by the movement of the permanent magnet returns the magnet and piston rod to their initial positions where they are set for a repetition of the operating cycle of the generator system.
