CPC H02J 50/40 (2016.02) [H02J 7/0013 (2013.01); H02J 7/04 (2013.01); H02J 50/10 (2016.02); H02J 50/80 (2016.02)] | 20 Claims |
1. A wireless power system comprising:
a phase locked loop (PLL) providing an input signal tuned in frequency;
a plurality of dividers coupled to the PLL to divide the frequency of the input signal, wherein the plurality of dividers provides a plurality of phases for the input signal;
a plurality of phase interpolators electrically connected to the plurality of dividers to generate multiple phases based on the input signal, each divider associated with a group of phase interpolators; and
a plurality of drivers electrically connected to the plurality of phase interpolators, the plurality of phase interpolators selecting phases from the plurality of phases for the input signal to digitally direct a plurality of output signals from the plurality of drivers each having a different frequency to a plurality of sensor clusters, each sensor cluster operating at a different frequency, wherein electromagnetic coupling is used for near field sensor clusters and radiating elements are used for far field sensor clusters.
