Abstract
A power capacitor () is described for use in an RF power delivery system. The power capacitor comprises at least two RF electrodes () separated by a capacitor dielectric () comprising a solid paraelectric dielectric material whose relative permittivity is controllable by varying a DC bias voltage applied across the dielectric () at DC bias electrodes (). Composite capacitor configurations, an RF power system and a method of controlling the power capacitor are also described.
