    摘要： Provided are a flexible variable capacitor and method for preparation thereof. The flexible variable capacitor includes two highly conductive flexible electrode layers and an elastomer dielectric insulation layer disposed between the two highly conductive flexible electrode layers, wherein the highly conductive flexible electrode layers include first polymeric elastomer and carbon nanomaterial, and the elastomer dielectric insulation layer includes second polymeric elastomer and functional ceramic nanoparticles. The method for preparation of the flexible variable capacitor is as follows: first, preparing an elastomer composite film with different functions, and then pressing upper and lower electrode layers with the intermediate elastomer insulation layer together to obtain a stretchable strip-shaped plate capacitor. Different from existing technologies, the present application uses independently developed highly conductive flexible electrodes to replace traditional silver oil electrodes, which greatly reduces the cost of variable capacitor devices, and enhances the integration and operability. The prepared flexible variable capacitor has characteristics such as high dielectric constant, low dielectric loss, simple preparation process, and capacitance being sensitive to deformation.

    摘要： A capacitor provides a plurality of selectable capacitance values, by selective connection of six capacitor sections of a capacitive element each having a capacitance value. The capacitor sections are provided in a plurality of wound cylindrical capacitive elements. Two vertically stacked wound cylindrical capacitance elements may each provide three capacitor sections. There may be six separately wound cylindrical capacitive elements each providing a capacitor section. The capacitor sections have a common element terminal. A pressure interrupter cover assembly is sealingly secured to the open end of case for the elements and has a deformable cover with a centrally mounted common cover terminal and a plurality of section cover terminals mounted at spaced apart locations. A conductor frangibly connects the common element terminal of the capacitor section to the common cover terminal and conductors respectively frangibly connect the capacitor section terminals to the section cover terminals. Deformation of the cover caused by failure of the capacitor element breaks at least some of the frangible connections sufficient to disconnect the capacitive element from an electric circuit in which it is connected. A cover insulation barrier mounted on the deformable cover, has a barrier cup substantially surrounding the common cover terminal and a plurality of barrier fins each extending radially outwardly from the barrier cup, and deployed between adjacent section cover terminals.

    摘要： A new composition of matter, and more specifically a new compound, includes two or more highly resistive materials integrated into the chemistry of the grain boundary of an internal barrier layer capacitor material. This new compound includes a high permittivity and high resistivity dielectric compound. This new compound has high permittivity, high resistivity, and low leakage current. In certain examples the new compound can be used to create a dielectric energy storage device that is a battery with very high energy density, high operating voltage per cell, and an extended battery life cycle.

    摘要： A high power low frequency tuner uses motor controlled rotary capacitors submerged in low loss high epsilon dielectric fluid and lengths of semi-rigid RF cable interconnecting the floating static blocks of the capacitors, the rotating blocks being grounded. And tuner calibration and tuning methods, allowing accurate tuning and perfect Smith chart impedance coverage. The full calibration lasts several hours and is reduced by the “de-embedded” calibration algorithm to minutes. A maximum power embodiment comprises full immersion of capacitors and interconnecting cables in circulated dielectric liquid (mineral oil) for breakdown voltage increase and heat removal.
