Abstract:
A methodology for efficiency recovering in Wireless Power Transfer (WPT) systems under a misalignment condition between driver and receiver is presented. The configuration is made by an array of passive resonant elements placed in the proximity of the driver coil of a common 2-coils system. The method is based on one numerical full-wave evaluation of the scattering parameters matrix of a 2-coils system together with a passive resonant array of (N-2) elements, made resonant by tuning capacitors. By a post-processing evaluation of the SNxN matrix of the system, it has been demonstrated possible to partially recover the efficiency from the drastically reduced value caused by a misalignment of the receiver coil into respect to the driver coil, by acting only on the tuning capacitors.
