Abstract

The invention relates to a variable capacitor which, due to its particular arrangement of electrodes, enables a significantly higher current flow than generally known constructions having the same or a similar structural shape, said capacitor also has an increased life expectancy and is compatible with existing capacitors in terms of connection. Such variable capacitors can be used in high frequency generators, in matchboxes and in interface networks for industrial high frequency applications, as regulatable filters in high frequency power electronics and in the power part of emission installations.
