Abstract
Background:
As wireless energy transmission technology advances, the demand for energy
directional transmission increases.
Objective:
Transfer of energy in the specified direction and increase in transmission power.
Methods:
A novel three-coil transmitting structure was proposed, which can transmit energy to a
specified single or multiple space regions, and enhance the magnetic field strength in a single direction
by magnetic field vector synthesis to improve the transmission power.
Results:
Combined with Mathcad numerical calculation and Maxwell simulation analysis, the experimental
platform was built and the magnetic focusi of the proposed novel structure was experimentally
verified.
Conclusion:
The novel emission structure can effectively perform directional energy transmission
and increase the transmission power by 2~3 times in a single direction at the cost of 10%~15% efficiency
loss.
