Integrated Simulation-Based Design Environment

At this point in time, existing capacitors technologies fail to meet satisfactorily Navy application needs for parts that are able to deliver energy densities greater than 1 J/cc and that are able to operate in severe conditions such as high temperatures,high operating voltages, and high currents. As a solution to this problem, Sigma proposes to develop a unique multilayer capacitor architecture to produce parts that are projected to deliver energy densities over 10 J/cc. These parts will be rugged enoughto withstand the harsh conditions. In the phase I program, we propose to design and fabricate high voltage, high current, high temperature capacitors, with an energy density in the range of 10-20J/cc, based on existing and proven capacitortechnology. The new capacitor design will based on Sigma's new nanocomposite patented technology that allows the production of polymer/inorganic multilayer capacitors that have improved self healing characteristics, higher breakdown strength, lowerdielectric absorption and superior thermal and mechanical properties which result in higher current carrying ability. In the Phase II program, specific DOD applications will be addressed and capacitors will be produced and delivered for field testingThenew generation high energy density capacitors will serve a multitude of critical high power defense and commercial applications which may include motor controllers, inverters, power conversion, advanced linear motor, implantable defibrillators, pulsedlasers, electromagnetic catapults, high energy switches, radar modulators, isotope separation lasers, directed energy weapons, countermeasure pulse generators and other applications in the power electronics industry
