- To design and implement a cost-effective wireless transfer system.
- To design a relaxation oscillator.
- To design an ac signal amplifier.
- To design LC circuits with high Q-factor.
Wireless power transfer may seem like science fiction, but the idea is more than 100 years old. Around 1900 Nicola Tesla claimed to be able to radiate power over long distances with minimum loss of power, took a patent, and even got some industrial finance for trials.
These failed. Hundred years later, an electric toothbrush using a Contactless inductive charging device is a common commodity in many households. Even more, recently new breakthroughs are claimed to radiate enough energy from a power outlet to feed a nearby low-voltage lamp or electronic device using radiofrequency radiation over a distance of one meter. In this project, I want to design a wireless system that can light a standard room, eliminating the use of wires completely at a relatedly lower cost.
Purpose of the study
The main objective of this project is to present the status of the current trends and implementation of a wireless power transfer system.
