We have demonstrated a WPT network architecture, which
can harvest powers from multiple TX and deliver the powers to
multiple RX. The system performance has been examined by
theory and verified by experimental setups of 2 × 2 and 4 × 6
systems. The power transfer and system efficiency can be significantly
enhanced by utilizing a RP coil. The coil orientation is an
important factor as it varies the power flows from TX to RX. The
results from a scaled system with four TX and six RX show that
the system can operate at a sufficient efficiency when the source
or load dynamically drops out of the grid. These demonstrations
show feasibility for future implementation of large-scale electrical power combining and distribution in the free space and
possible applications utilizing management of dynamic power
flows. Future wireless power systems may incorporate optimal
designs of RP to control the power flows adaptively in order to
maintain the system at maximum efficiency.
