Battery Charging Circuit of Wireless Power Transmission Receiver Side for Electric Bicycle

In this paper, we design a low component-intensive charging circuit for a wireless power transmission system, which is applied in an electric bicycle. The system is composed of a rectifier, a driving circuit, a primary power topology, and a sampling feedback topology. The circuit can be used as the secondary side circuit of a wireless power transmission system for an electric bicycle battery as the receiving end of electromagnetic energy transmission. The circuit topology has low electronic component density, which is used to promote the use of electric bicycles on a larger scale. In order to verify the propose circuit, simulation results and experimental results are presented, which well validate its feasibility.
