Abstract—Future applications of wireless power transfer
will include powering various devices in a room, charging
electric vehicles in a parking area, charging moving robots
and so on. Therefore practical wireless power transfer must
be able to support complicated configurations for example
combination of multi-receiver and repeaters. Many past
works have discussed on methods for improving efficiency
and more recently extended the methods to multi-receiver
system. However controllable power division among receivers
is also an important feature as receivers nearer to the
transmitter tend to absorb more power compared to further
antennas. In this paper, a new impedance matching and
power division method utilizing impedance inverters only
at receiver sides is proposed. The mathematical equations
in the proposed method are then generalized for arbitrary
number of receivers and arbitrary number of repeaters.
