Project: Resonance Based Wireless Power Transfer
Abstract
This Project focuses on Wireless Power Transfer System, which allows
transferring wireless energy with spatial freedom. We have researched and
modeled the entire Wireless Power Transfer System and its components. System
efficiency is the main goal of this project. In the design process all factors that
impact the system efficiency have been considered and analyzed carefully. We
have used a cellular phone as our load model. Load model is considered to
determine the size of the receiving coil. The concept of resonance between two
objects is the key to this project. Also, system component were designed from
basic electrical elements. At high frequencies, impedance is frequency, distance
and load dependent. It is very important to have impedance matching network in
order to achieve resonance and make the system efficient. Hence impedance
matching in the receiver as well as the transmitter chains was taken into
consideration. We have successfully modeled the system and its components and
tested each component separately.
