Furthermore, Ansys/Maxwell simulations are completed to
analyze magnetics of each charging situations and explained
the power changing rule by extracting parameters from
Ansys/Maxwell to WPT system model in LTspice for all
charging combinations. In this paper, simulation of one
situation is presented to explain why adding a second Rx will
change the charging power of the first Rx and why the Rx
closer to the Tx coil will receive more power than the other
one. However, two phones cannot have the same power as of
charging only one phone. This problem will be the next target
of investigation
