Abstract
A vacuum variable capacitor includes a vacuum bellows for allowing a pressure differential between two volumes inside the capacitor, wherein one of the volumes may be a vacuum volume. The vacuum variable capacitor further includes a conductive bellows disposed within the vacuum volume. In such an arrangement, the materials selected for the vacuum bellows and the conductive bellows may be selected to optimize the function of each bellows.
