Publikation: Patent


An active two-terminal capacitor device with a controllable capacitance based on a capacitance value input C_I. A processor system PRS executes an algorithm which controls a power converter PCV with controllable electric switches connected to the two external terminals A, B along with a fixed value capacitor component CI. Based on sampling of at least the voltage across the capacitor component CI, the algorithm controls the power converter PCV to provide a resulting capacitance across the external terminals A, B which serves to match the capacitance value in ut C_I.
