In this work, theoretical and experimental results of solid-state resonant circuits for the transmission and reception of wireless electrical energy, for applications in mobile devices are presented. Analytical expressions are found to calculate the voltage range as a function of the distance between the emitter and the load, as well as the current at the front end of an electromagnetic wave receiver. These expressions show the parameters to be varied to achieve a greater range in the transmission of wireless electrical energy. The transmitted voltage and current are measured by an electromagnetic wave receiver and compared with theoretical values, finding an excellent correspondence between the two.
Se realiza un estudio tanto teórico como experimental de los circuitos resonantes aplicados a la transmisión y recepción de energía eléctrica inalámbrica. Se construye una bobina de Tesla de estado sólido para lo cual, se calcula la frecuencia de resonancia y el voltaje máximo que se genera al tener una carga en la punta de la bobina secundaria. Mediante un receptor de ondas electromagnéticas diseñado para resonar a la misma frecuencia de la bobina de Tesla, se mide el voltaje emitido por el secundario. Mediante un microcontrolador PSoC, se despliega en una pantalla LCD para medir el alcance, la frecuencia, la potencia y el voltaje efectivo del secundario.
