Characteristics comparison of typical secondary-side compensation topologies in wireless powering systems with constant-current primary-side

This paper compares the characteristics of serial, parallel and LCC compensation topologies of secondary-side in wireless powering systems with a constant-current primary-side. The topologies characteristics of power, efficiency and load are carefully analyzed and detailed presented. And the correctness of theoretical analysis is verified by simulations. This study results can guide the selection of compensation topology in practical application.
