Unconventional Compact Wound Glass Capacitors for Pulsed Power System in RF Accelerators

Capacitors are critical components in power modulator systems for radio frequency accelerator technology, in power electronics in electric vehicles, wind energy, and photovoltaic panels, and in directed energy weapon systems. Current capacitors have low energy density and occupy 25-50% volume of the devices. We propose to develop unconventional wound glass capacitors with high energy density, high temperature stability, and low dielectric loss. The capacitors will combine high energy density, self-healing feature, and low-cost commercial manufacturability. Commercial Applications and Other Benefits: The high energy density wound glass capacitors with high reliability will enable the miniaturization of many power electronic devices. Potential applications include capacitors for hybrid electric vehicles, plug-in electric vehicles, high power strobe lights, defibrillators, directed energy weapon systems, and uninterruptable power supplies.
