Wireless Power Transfer System Turns on LED TV from 16 Feet Away
Added Apr 25, 2014 | Rate View top rated
Chun T. Rim, a professor of nuclear and quantum engineering at KAIST (Korea Advanced Institute of Science and Technology), and his team recently showcased a great improvement in the distance that electric power can travel wirelessly. The research team developed the Dipole Coil Resonant System, or DCRS, for an extended range of inductive power transfer up to five meters (over 16 feet) between transmitter and receiver coils. One large LED TV and three fans (40 W each) can be powered simultaneously through DCRS. It transfers a maximum output power of 209 W at a time. "Although the long-range wireless power transfer is still in an early stage of commercialization and quite costly to implement, we believe that this is the right direction for electric power to be supplied in the future. Just like we see Wi-Fi zones everywhere today, we will eventually have many Wi-Power zones at such places as restaurants and streets that provide electric power wirelessly to electronic devices," says Rim.
