In this paper a comparison between a LCCL and CLLC resonant compensations for Capacitive Wireless Power Transfer (CWPT) system is presented. A review of several compensation topologies is presented. From this analysis emerges that these two topologies represent the more promising compensation for high power applications, such as Electric Vehicle (EV) wireless charging. The frequency behavior of each topology is analyzed studying the equivalent input impedance and the voltage transfer function. After design of each compensation to operate at optimum operating condition, the output power and the efficiency are evaluated under load, coupling parasitic resistances variations through LTspice simulations.
