Analysis of Wireless Power Transmission System Behavior for Various Compensation Topologies

This paper presents wireless high-power transfer application in wireless chargers for electro mobility, cordless tools e.g.. It discuses mutual influence of rectifiers and wireless power transfer coupling elements in various compensation topologies. The basic and derived topologies are discussed together with various rectifier topologies. Influencing factors are discussed theoretically and are further practically verified by laboratory testing. Finally, the paper presents optimal wireless power transfer and rectifier topologies combinations for specific application areas of wireless power transfer.
