Abstract

A liquid filled variable capacitor or PFL which provides variable frequen impedance, and pulse length without changing the capacitor or PFL hardware. The capacitor is constructed from two or more conducting surfaces. A dielectric fluid mixture separates the conductors. A fluid supply system furnishes the dielectric fluid mixture to the conductors and provides for varying of the dielectric constant of the fluid and thus the capacitor operating characteristics, by varying the mixture composition. The fluid supply system has a mixing tank connected to both a supply of high dielectric constant fluid and a supply of low dielectric constant fluid. The high dielectric constant fluid and low dielectric constant fluid are mixed proportionally to obtain a dielectric fluid having the desired dielectric constant. A pump conveys the dielectric fluid between the mixing tank and the conductors while a heat exchanger controls the temperature of the dielectric fluid.
