Abstract - Wireless power transfer via magnetic resonant
coupling has been extensively researched for various
applications. Impedance matching is implemented so that the
transfer system is resilient to positional changed and load
changed. Recently powering multiple loads simultaneously is
becoming the focus in wireless power transfer researches and
designs. Apart from maintaining high efficiency, controllable
power division is also an important feature in multi-receiver
system. This is due to ratio of power division depends not only
on the load but also on the gap of each receiver to the
transmitter. On the other hand, cross coupling exists when
receivers are placed relatively near to each other. In this paper,
novel algorithm is proposed for impedance matching and power
division considering cross coupling in between two receivers.
The wireless power transfer system is first represented by
equivalent circuit and the algorithm for impedance matching
and power division is derived. The new method is then verified
using simulations.
