The Applications of Resonant Energy Transfer via Inductive Magnetic Coupling

CSEF · 2010 Electronics & Electromagnetics

Alex Hang, Duy Nguyen · Oak Grove High School, San Jose, Santa Clara County

Overview

Objectives/Goals To manipulate factors in order to maximize efficiency output, increase the transmitting power and finally, to integrate applications to everyday use. Methods/Materials RF amplifier Oscilloscope Function generator Copper coils/tube LED Incandescent light bulb Power outlet Multimeter Meter Stick Results During our experimentation, we were able to power LEDs wirelessly at an approximate range of 3 feet. Conclusions/Discussion In the end, we were able to successfully light a gauge 18 copper coil, with 20 revolutions, that has 2 3volts LEDs; the coil was resonating at 3.38 MHz and had a max distance of 60 cm. Many of the other coils reached similar progress. It is possible to light all six coils at once using only one transmitter, the circular loop that was created by alligator clamps. We discovered that 2.1 MHz all the lights lit up.
