What is it about?
Inductive power transfer is more and more applied in electric vehicles. A model of LCC-S compensation network is built up,the resonant conditions for realizing constant current (CC) output and constant voltage (CV) output with loads independent are revealed. By analyzing the leakage inductance equivalent circuit of the LCC-S resonant network, the relation between efficiency with frequency, coupling coefficient and loads are revealed. An optimal parameters tuning for working at the maximal efficiency state in both CC mode and CV mode is designed through changing frequency and adjusting the coupling coefficient.

Why is it important?
The relationship between the efficiency of the resonant network with the coupling coefficient, frequency and loads are analyzed, based on which an optimal parameters design for working at the maximal efficiency state in both CC mode and CV mode is designed through changing frequency and adjusting the coupling coefficient. Simulation results validated the theoretical analyses and proposed optimization scheme.
