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: In a single-phase or balanced polyphase circuit, the two factors which are contributory to power factors less than unity are wave distortion and phase displacement between current and ...

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 ...

The possibilities of alternating current by no means stop with using a single source. Ordinary household current in the US is at 60 Hz and about 120 volts. We have, in other words, a single undulating ...

Wireless power transfer (WPT) is an essential technology enabling automated charging of electric vehicles with safety, convenience, and flexibility while having high efficiencies. High-power wireless ...

In honor of the recent news that the not-for-profit Tesla Science Center at Wardenclyffe has signed a letter of intent to acquire Tesla’s lab and property on Long Island, NY, EDN celebrates one of ...

This implementation of APS is based on the following paper from the Computer Vision and Pattern Recognition (CVPR) 2021 conference: Chaman, A., & Dokmanic, I. (2021). Truly Shift-Invariant ...
