Abstract
Energy management circuits are indispensable for wireless power transmission via inductive links to realize high efficiency in spite of the electronic losses and coil position perturbations. This chapter examines the most popular energy management circuits applied to the sending and the receiving side of inductive power transmission systems. First of all, we examine coil shape and orientation. Then, the energy management design of the sending side and receiving side are illustrated, and the system topology is presented in detail, including resonance circuits and the necessary transformations. Finally, different approaches for control systems in the inductive power transmission are summarized.
