Efficiency Improvement for Three-coil Cooperative Inductive Power Transfer Systems
A compensation method has been proposed for three-coil inductive power transfer (IPT) to realize cooperative transmission with load-independent output voltages. However, the existing configuration has not considered the mutual coupling between the primary coil and the secondary coil, and for that reason it suffers from an efficiency degradation when significant cross coupling exists. This paper proposes a novel configuration to improve the efficiency while maintaining the constant voltage functionality for the cooperative IPT system. EM simulations and experiments verify effectiveness of the proposed scheme.
