ORNL’s Omer Onar, left, power electronics research lead, discusses the 270-kW wireless charging system’s lightweight polyphase electromagnetic coupling coil, pictured in foreground, with Lee Slezak, ...

Abstract: The paper proposes a new framework for characterizing instantaneous non-active (reactive) power in general polyphase systems. The framework is based on the concept of multivectors, which are ...

Abstract: High phase order transmission systems (e.g., n φ ≥ 6) are revisited with a specific focus: the operation of a polyphase system with one phase out of service. The resulting voltage at the ...

Researchers at the Department of Energy’s Oak Ridge National Laboratory have successfully demonstrated the first 270-kW wireless power transfer to a light-duty electric vehicle. The demonstration used ...

The polyphase channelizer [1] down-converts simultaneously a set of frequency-division multiplexed (FDM) channels carried in a single data stream using an efficient approach based on digital signal ...
