Aero Propulsion and Power Technology

This Phase I SBIR program will demonstrate the production of high temperature,high saturation inductance magnet materials and power converter circuit designsfor directed energy laser power supplies. Powdermet will manufacture and characterizea series of articicially structured metallic magnets with controllable permeabilitiesand low losses at 300 C. These insulating ferromagnetic heterostructures resolvetemperature limitations of ferrites enabling high efficiency directed energy powersupplies to be produced and used without excessive cooling requirements. The proposed high temperature, tailorable permeability magnet materials will resolveperformance limitations in directed energy power supplies. Commercial applications ininduction motors, switch-mode power supplies,and fast selenoids will benefit from thetechnology.
