Analysis of Compensation Topology of Magnetically Coupled Wireless Energy

Compensation topology is an important part of the magnetic coupling wireless energy transmission system, which is of great significance for improving system efficiency and minimizing device stress. Firstly, the classification and evolution of the compensation topology is introduced, and then the equivalent circuit models of various topologies is derived by using the fundamental wave approximation method as a tool, the parameter design methods of the topology are obtained, and the output characteristics of these topologies are. Finally, based on the same set of coils, the circuit characteristics of the system under different topologies are quantitatively analyzed, and the advantages and disadvantages are summarized.
