Design of Wireless Electromagnetic Energy Transfer Systems


This paper presents a set of diagrams for wireless power transfer systems (WPTS) with applications in key domains such as: medical, electrical engineering, military, etc. Our research is based on original circuits working as WPTS. All the circuits are using sets of two magnetically coupled coils whose parameters were extracted by simula-tions using the specialized software ANSOFT Q3D Extrac-tor. The simulations of the circuits were performed using TINA, PSpice and Simulink in MATLAB. We used existing parts libraries from Texas Instruments. The circuits were also physically built and tested and the results were very close to the numerical ones. We also compared the results with data in existing literature and we obtained an accept-able computation error. We also studied the efficiency of the power transfer and presented some practical applications for these systems such as low power battery chargers. images
