Design of A Simple Wireless Powering System XIA ,Zenglin CHEN,Qijun Department of Control Science and Engineering, Tongji University, Shanghai 200092, P.R.China Abstract: Wireless powering system is a new technique, which is convenient and safe. Power energy can be transferred to the load without any physical connections. Based on electromagnetic coupling, this paper presents a simple wireless powering prototype, as well as its primary analysis and discussion. It works like a loosely coupled transformer whose primary side and secondary side are detachable. Ferrite pot core is used to improve the coupling efficiency and reduce the magnetic leakage.
