Modeling, characterization and evaluation of MU100 high-energy density ceramic nanodielectric for use in pulsed power applications
Abstract
A high dielectric, nanodielectric, composite material, MU100, was developed by the University of Missouri for use in dielectric loaded antennas. Based on its dielectric strength and losses, MU100 had possible uses in the development for high energy-density capacitors. This work presents the theory behind, methods of preparation and evaluation, modeling and properties of MU100. MU100’s dielectric properties are explored in high energy-density pulsed power applications, compact high voltage capacitors. Small scale tests have shown the average dielectric strength of MU100 to be 225 kV/cm with a peak break down field of 328 kV/cm. When potted, these small-scale capacitors have lifetimes in excess of 800,000 discharges at 80% of their maximum rated field strength. This shows a remarkable development in the performance of high energy density capacitors for use in pulsed power applications.
