Detuned Resonant Capacitors Selection for Improved Misalignment Tolerance of LCC-S Compensated Wireless Power Transfer System

“…To improve the power transfer performance of the WPT system, the resonant compensation topology must be implemented in the primary and secondary side circuits. There are four basic compensation topologies, namely SS, SP, PS, and PP topology, in which "S" means the LC series resonant circuit that is composed of coils and compensation capacitors, and "P" represents the LC parallel resonant circuit that consists of the same components [10], [11]. SS topology is the most commonly used of these four topologies due to its simple structure, coupling coefficient independently compensated capacitors design, and constant output current characteristic.…”
