Resumen

An important challenge in the wireless power transfer is the sizing of the coils for transmission and energy reception. The output power in a wireless power transfer system can be determined by analytical formulation, however the effects of using some geometry or material for the transmission and receiver coilassembly is not easily quantifiable by analytical method. This work quantifies by numerical simulation the impacton output power changing the separation between the transmitter coil and receiver, materials, geometries and number of turns. The quantifies obtained allowed to determine a model for coupling coefficient to compute optimal frequency for the power transfer. The analysisand evaluation of these parameters were developed through electromagnetic simulator with finite element, the work considers planar circular and square coils. The document contributes to identify the important parameters to be controlled or modified in the coils withthe goals to optimize the power transmission for awireless system.
