Charging mobile electronic devices is a hot topic in the field of wireless power transfer. The change of mutual inductance during the movement of the electronic device will cause the output voltage to fluctuate and the power transfer efficiency to drop. In order to solve these problems, this paper proposes a CLC compensation network that is embedded between the power supply and each transmitter coil. Optimizing the parameters of the CLC compensation networks can ensure that the position-varying load obtains stable voltage while ensuring high power transfer efficiency. Specific theoretical analysis of output voltage control and power transmission efficiency optimization is detailed in the article. Finally, a typical experimental platform is established and the result of the experiment can verify the theory.
