This paper presents the conditions for achieving maximum power output and maximum efficiency in a series- series (SS) resonant inductive link. It has been shown that output power depends on the nature of supply: current source or voltage source, resulting in different values for the same resonant link setup. For both types of sources, conditions for maximum power transfer with respect to different parameters have been derived. Efficiency, on the other hand, is independent of the nature of supply; it depends only on circuit parameters. Conditions for maximum efficiency with respect to circuit parameters have also been derived. It has been shown that an SS resonant inductive link is best suited for current-sourced input, since a voltagesourced link behaves poorly when deviated from ideal tuning conditions. Moreover, for a voltage-sourced link, there exists an optimum value of mutual inductance at which maximum power transfer occurs. However, for a current-sourced link, output power increases with increase in coupling coefficient. The modeling and analysis has been supported with detailed simulation and experimental results. © 2016 IEEE.
