Implementación de un sistema de transmisión inalámbrica de energía eléctrica a través de acoplamiento resonante magnético de campo cercano para dispositivos de bajo consumo de potencia en el hogar.

Abstract

The present research work, entitled " Implementation of a wireless transmission system of electric energy through magnetic resonant coupling of near field for low power consumption devices in the home" was intended to develop electric power methods according to the modernization and technological advance of society. Mathematical methods tested in previous research contributions were used for the design of the antennas responsible for the wireless transmission of energy with microstrip technology, on an FR4 substrate, in addition, was used integrated circuits with MMIC technology for the generation and amplification of radio - frequency waves in the range of 16 MHz to 23 MHz as an energy source. In the reception, a 3-stage voltage doubling circuit is used for the purpose of rectifying and amplifying the received signal. The results obtained in the implementation of the system, show a reception of the energy received between 20% and 30% of the total transmitted, for distances between 10 and 90 millimeters between the antennas without obstacles. This research indicates that it is feasible to use wireless power to charge devices with low power consumption, verifying that, with obstacles, the efficiency of the system decreases when passing through materials such as agglomerate, plastic, glass, expanded polystyrene, cloth and wood, totally losing the performance with metal.
