Abstract: A high-voltage capacitor includes a gas-tight enclosure containing interleaved electrodes. The dielectric of the capacitor is a pressurized gas at a pressure of at least 6 bar, and preferably 10 or 15 bar. In order to withstand this level of internal pressure, the insulating body section of the capacitor may be formed of a high-strength polymeric material.

Abstract: A vacuum variable capacitor includes a vacuum sealed enclosure to contain a vacuum dielectric medium, wherein the enclosure includes a first plate and a second plate, the first plate and the second plate being separated by an electrically insulating element, a fixed electrode attached inside the enclosure to the first plate and a movable electrode attached to a movable plate, wherein the movable plate is attached inside the enclosure to the second plate by at least one vacuum bellows, wherein the vacuum capacitor includes a mechanical drive system for displacing, in particular translating, the movable plate relative to the first plate so as to vary the capacitance of the vacuum capacitor, wherein the mechanical drive system includes a ball screw arranged to drive the movable plate and wherein the mechanical drive system includes outside of the vacuum sealed enclosure a limiting element limiting the maximum distance between the first plate and the movable plate and wherein the drive system includes a nut attached to the ball screw, wherein the nut includes a first shoulder configured to abut against the limiting element to limit the maximum distance between the first plate and the movable plate.
