Analysis of WPT system using rearranged indirect-fed method for mobile applications
We investigate the indirect-fed magnetic resonant wireless power transfer system by rearranging the loops and coils used in the conventional wireless charging system for mobile devices. Three rearranged configurations (Out-Out, Out-In, In-In) have been considered and experimentally investigated by using hollow pipe copper loops (coils) and wire copper loops (coils). The power transfer efficiencies for the three configurations were similar. The highest measured efficiency of 82.5% was achieved at 35 cm distance between the Tx and Rx coils. We also investigated the practical application of the mobile device (note-pc), by rotating load loops and the Rx coil vertically, L-shape. The highest efficiency of the L-shape system, was 64.5 % at 45 cm distance between the Tx and Rx coils.
