High Speed and High Voltage Capacitors for Naval HPRF Directed Energy Applications Navy SBIR FY2014.2 Sol No.: Navy SBIR FY2014.2 Topic No.: N142-123 Topic Title: High Speed and High Voltage Capacitors for Naval HPRF Directed Energy Applications Proposal No.: N142-123-0584 Firm: PolyK Technologies, LLC 1981 Pine Hall Road State College, Pennsylvania 16801-2435 Contact: Nanyan Zhang Phone: (814) 308-0778 Abstract: We propose to develop polymer-based negative-positive-zero (NPO) capacitors by combining our proprietary dielectric formulations, film processing technology, and unique capacitor design. As polymer film capacitors have intrinsically high dielectric breakdown strength than multilayer ceramic capacitors (MLCC), our capacitors will be able to provide high operation voltage > 80 kV. The dielectric formulation and capacitor design will be optimized to minimize the equivalent series resistance (ESR) to achieve the high speed discharging. The self-healing process of polymer film will enable the reliable operation of the capacitors at high electric field close to its breakdown strength without failure, therefore, provide energy density higher than 1 J/cc. Benefits: Potential commercial applications include a variety of communications, sensor and medical applications using high power RF systems requiring compact, high speed and high voltage capacitors. Capacitors are common across a variety of electronic applications from current blocking, signal filtering, voltage stabilization, frequency tuning, to active power control. As systems get smaller, higher voltage and faster acting capacitors would be an enabler for commercial RF generation related systems. The commercial potential for new and more dynamic system applications would be enabled by lower cost, more reliable, better protected compact high voltage capacitors. Return
