Chris Vanek, a senior electronics engineering technology major, worked on sponsored research by the United States Naval Research Laboratory in Washington, D.C., on wireless power transfer (WPT) technology. He designed and implemented a 4-MHz inductive-resonance WPT system that transferred 75 W of power wirelessly to a light bulb.
The WPT system, designed under the guidance of Biswajit Ray, professor of EET, worked up to a separation distance of 50 cm between the transmit and receive coils. The wireless power transfer technology is becoming increasingly popular for consumer electronics, electric vehicle charging, and implantable biomedical devices.
The current engineering challenge is to design systems that maintain high power and high efficiency capability for dynamic loads with changing distance and orientation.
