TL;DR: Using the presented optimization approach, a generator design with the desired sinusoidal cogged torque pattern is obtained, achieving a total cogging torque reduction of the overall electromechanical energy harvesting system of 90%.

TL;DR: In this article , the authors investigated the advantages and disadvantages of a combination of series-and parallel-interleaving in terms of losses, volume and complexity scaling of UHBW-PAs.

TL;DR: In this article, a 1.5-kW, 12-V-output DC/DC converter for industrial power supplies that is required to operate across a wide 300-V −430-V input voltage range is presented.

TL;DR: In this paper, the authors proposed a speed detecting device that includes a magnetic flux producing unit (MFF) for producing magnetic flux changing at a predetermined frequency so that a magnetization pattern is formed on a principal surface (6a) of a relative moving body (6b) as the moving body(6c) moves or rotates.

TL;DR: This work presents a universally applicable design procedure for miniature bearingless slice motors intended for rotational speeds of several hundred thousand revolutions per minute, illustrated and facilitated to facilitate the selection of Pareto-optimal implementations.
