Abstract
An electrical resonance network comprising a first capacitor and a first inductor whose resonance frequency can be tuned by means of a second capacitor and/or a second inductor. The resulting effective capacitor- or inductor value of a network period is controlled by a variable coupling respectively decoupling interval by means of at least one coupling switch. The coupling respectively decoupling interval is synchronized by a sign change of a current and/or voltage in the network.

An electrical resonant network in which at least one of a resonance frequency, an impedance and an admittance are controlled, said electrical resonance network comprising:
- a) at least one resonant circuit including at least one first inductor and at least one first capacitor;
- b) at least one reactive component;
- c) at least one switch controlled by at least one ON/OFF coupling signal for coupling said reactive component to at least one of said first inductor and said first capacitor, wherein said reactive component is charged and discharged by said resonant circuit and said at least one ON/OFF coupling signal alters its state at least once within a resonant circuit period;
- and
- d) a control circuit for generating said at least one ON/OFF coupling signal, wherein a first transition change in said at least one ON/OFF coupling signal is responsive to a control signal for controlling the at least one of the resonance frequency, impedance or admittance of said resonant network, and a second transition change in said at least one ON/OFF coupling signal, opposite to said first transition change in said at least one ON/OFF coupling signal is responsive to a state transition in said at least one switch.
A method of controlling at least one of a resonance frequency, an impedance and an admittance of a resonant circuit including at least one first inductor and at least one first capacitor, said method comprising;
- coupling at least one reactive component to said resonant circuit based on at least one ON/OFF coupling signal during a coupling interval, the coupling interval changing at least once within a resonant circuit period and said at least one reactive component is charged and discharged by said resonant circuit, and
- generating said at least one ON/OFF coupling signal, wherein a first transition change in said at least one ON/OFF coupling signal is responsive to a control signal for controlling the at least one of the resonance frequency, impedance and admittance of said resonant circuit, and a second transition change in said at least one ON/OFF coupling signal, opposite to said first transition change in said at least one ON/OFF coupling signal, is responsive to a state transition in said at least one switch.
