Wireless Transmission of Electricity

CSEF · 2017 Electronics & Electromagnetics

Wyatt C. DeCraemer, Sergio I. Lozano · Sundale Union Elementary School, Tulare, Tulare County

Overview

Objectives/Goals The objective of this project is to design an effective way to transmit useful electricity wirelessly. Methods/Materials A solid-state wireless electricity transmitter (Tesla coil) with input of approximately 30 volts. A smaller receiver coil with a full bridge rectifier to produce useful DC, and a few florescent light bulbs. Improve the transmitter with the engineering design process to yield greater distance. Results Six different versions of the design had varying levels of success. The final and most efficient was a 30 volt power transistor driven transmitter with up to a meter in range. Conclusions/Discussion Repeated trials proved that higher voltages yield greater power and distance, but as a disadvantage, a proportionally increasing amount of heat. It is concluded that the greater the performance becomes.

Summary statement

We showed that a low voltage Tesla Coil is an effective way to transmit long range wireless power.
