Abstract

In order to achieve single-to-multiple high-efficiency wireless power transfer, this paper provides a design strategy for output efficiency optimization using the LCC compensation topology. To overcome the interference of the mutual inductance between the receivers to the current of the transmitter coil, the transmitter adopts the LCC topology and sets it to a load-independent constant current (CC) output mode. In order to further improve the coupling coefficient between the transmitting coil and the receiving coil, and achieve high-efficiency of both single-to- single and single-to-multiple energy transmission, a quasi-DD coil wound with the same magnetic polarity is designed. High anti-offset capacity, high-efficiency energy transmission can still be achieved when the receiving coil is offset or cut in and out. This paper provides a detailed hardware design strategy, analyzes the energy loss in the transmission process, uses SIMULINK software to simulate and verify the designed parameters, and builds an experimental prototype with 76% energy transfer efficiency.
