| Abstract |
Proposed paper discusses FEM analysis, simulation and experimental verification of a low power, inductive, wireless energy transfer system for rotating shafts. For the purpose of flexibility the secondary side design features a phase - shifted, double - layer PCB coil design, that can also be implemented on flexible FR4 laminate. Coil design data and basic properties are provided for a ferromagnetic core based transmitter design and PCB coil receiver configuration as well as ferromagnetic foil on the receiver side. Basic excitation system topology is described with main electrical waveforms. Hard switching operation waveforms and basic analytical and experimental results are given. |
