Connecting Second-Order and Higher Order Compensated Capacitive Power Transfer Converters

This paper first presents a systematic extension of basic second-order compensated capacitive power transfer (CPT) converters, designed for achieving load-independent current (LIC) or load-independent voltage (LIV) output, to higher order compensated CPT converters through adding an inductor or capacitor at the input or output side. Conditions on the parameters to achieve the required output are given. The analysis provides a convenient connecting pathway from second-order circuits to higher order circuits, mapping each type of topological extension with the specific performance outcome.
