Explosively driven pulsed power has developed significantly over the past few years in the form of Magnetic Flux Compression Generators (MFCG), Ferroelectric Generators (FEG), and Ferromagnetic Generators (FMG). However, two critical areas still need to be addressed to make it possible to use these technologies in small munitions. First, the generator output needs to be matched to the load in order to deliver maximum amount of power. A second problem with explosively driven generators is that they tend to be sensitive to high strain loads. HEM Technologies, with the Texas Tech University Pulsed Power and Power Electronics Center, propose to address these critical issues with several solutions focused on FEG technology.

Explosively driven pulsed power has developed significantly over the past few years in the form of Magnetic Flux Compression Generators (MFCG), Ferroelectric Generators (FEG), and Ferromagnetic Generators (FMG). However, two critical areas still need to be addressed to make it possible to use these technologies in small munitions. First, the generator output needs to be matched to the load in order to deliver maximum amount of power. A second problem is that they tend to be sensitive to high strain loads. This is especially true for FEGs. Therefore, survivability of the generators after the munition is fired, but prior to activation of the warhead is critical. HEM Technologies propose to address these critical issues with several solutions focused on FEG technology. Power conditioning of a FEG will be accomplished using a proven high voltage output pulsed power system to match the FEG output to high power microwave sources. Second, a compact attenuation system will be developed to protect the ferroelectric from the high shock loading associated with launching a projectile using conventional weaponry. The developed technology is expected to greatly increase the capability range of explosively driven pulsed power systems.
