VIRTUAL INFINITE CAPACITOR

摘要

A circuit that behaves as a non-linear capacitor over a predetermined operating range, the circuit comprising: an input node arranged to receive an input current; an input capacitor coupled to the input node; an energy storage component arranged to store energy; a control circuitry, comprising a non-linear controller, arranged to receive information regarding the received input current; a power converter coupled between the input capacitor and the energy storage component, the power converter responsive to the control circuitry, the control circuitry arranged to operate the converter such that over the predetermined operating range the voltage on the input capacitor is substantially unchanged irrespective of the total charge received at the input node.
