Modeling and simulation of inductive-based wireless power transmission systems

This chapter studies an inductive-based wireless power transfer system for low-power applications at short distances. The transferring power system has been modeled, simulated and analyzed via finite element method. A wireless power transfer system includes important parts such as coil, core and driver. In this chapter, the important parts of an inductive power transfer system have been analyzed. Receiving and transmitting printed spiral coils are designed in an optimized procedure. The experimental results were in a good agreement with the simulation results. Moreover, based on the performed modulation and simulation the use of the pot core as the receiving core is proposed. It is concluded that this type of core can improve magnetic flux density in the receiving side. Different geometries of coils for transmitting side have been modeled and simulated. An electromagnetic analysis has been done; the experimental result was in a good agreement with the simulation result. This work presents an efficient perspective to coil design

Resonant inductive coupling as a potential means for wireless power transfer to printed spiral coil

This paper proposes an inductive coupled wireless power transfer system that analyses the relationship between induced voltage and distance of resonating inductance in a printed circuit spiral coils. The resonant frequency produced by the circuit model of the proposed receiving and transmitting coils are analysed by simulation and laboratory experiment. The outcome of the two results are compared to verify the validity of the proposed inductive coupling system. Experimental measurements are consistent with simulations over a range of frequencies spanning the resonance
