Wireless energy transfer for low power charging applications

This activity focuses on developing a high-efficiency proof-of-concept prototype for a wireless energy transmission system. The objective is to utilize the technology for wirelessly charging multiple batteries in low power portable devices such as mobile electronics, e.g., personal digital assistants (PDA) and smart-phones. The system consists of two windings, transmitter and receiver, that are in parallel with capacitors to form two parallel resonant circuits. The two resonant circuits are then linked together through a magnetic coupling. The key function of the above power transmission system is to achieve higher wireless transmission efficiency through the resonance phenomena. Resonance will allow the system to oscillate at larger amplitudes at some frequencies than others. Examples of wireless energy transfer application are power-delivery in hazardous applications due to presence of gas, energy transfer to implanted medical devices through the intact skin, and electric vehicle battery-recharging applications due to enhanced safety, reliability, and convenience.
