Wireless power transfer

Abstract

In this project, the power transfer and the coupling between two partially coupled coils using a ferrite core were studied. Some approaches of the magnetic parameters that define the coupling between the coils were done by analytical calculations and also by simulations with FEMM. Then, the system was assembled, and some real measurements were taken, so the calculations that were done previously were checked with the values obtained by the real measurements. To finish, some measurements more were done to check the influence of the design parameters, air gap, number of turns and frequency, in the system. The general conclusions of checking the analytical calculations with the values obtained by the real measurements are that it is possible to achieved tolerable approaches with simple calculations. Regarding the real measurements, it was found that when the frequency was varied and the other parameters were fixed, the maximum efficiency, 18 %, is achieved working at 50 kHz and with a load resistance around 40 Ω. When the number of turns was varied keeping the other parameters fixed, it was found that the greatest efficiency, 23%, is achieved with 20 turns and using a load resistance of approximately 20 Ω . _________________________________________________________________________________________________________________________ En este proyecto se han estudiado la transferencia de energía y el acoplamiento entre dos bobinas acopladas usando un núcleo de ferrita. Se han hecho algunas aproximaciones de los parámetros magnéticos, inductancias, mediante cálculos analíticos del circuito magnético, así como simulaciones con FEMM. A continuación, se hizo el montaje del sistema en el laboratorio, y se tomaron medidas reales con las que se calcularon los mismos parámetros, pudiendo de esta manera comprobar los valores calculados previamente. Para finalizar, se hicieron varias medidas, para comprobar la influencia en la transferencia de potencia del sistema de varios parámetros de diseño, frecuencia, número de vueltas de las bobinas, “air gap”. La conclusión general de la comparación de los valores obtenidos en el laboratorio con los valores calculados a través de simulaciones y cálculos analíticos es que es posible alcanzar aproximaciones bastante tolerables con cálculos muy simples. En cuanto a las medidas experimentales, se llegó a que cuando se varía la frecuencia, dejando fijos el resto de parámetros, la eficiencia máxima, 18 %, es alcanzada trabajando a 50 kHz y con una resistencia de carga en torno a 40 Ω. Cuando se varía el número de vueltas de las bobinas, manteniendo el resto de parámetros fijados a un valor, se llegó a que la mejor eficiencia, que fue del 23%, fue alcanzada con bobinas de 20 vueltas y con una resistencia de carga de aproximadamente 20%.
