A main circuit of inductive power transfer system based on LCC‐S compensation network is built up. The resonant conditions for realising constant current (CC) output and constant voltage (CV) output with loads independent are revealed. By analysing 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 parameter 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. The theoretical analyses are confirmed by simulation results.
