Development of a 60 kHz, 180 kW, Over 85% Efficiency Inductive
... Abstract: Conventional contact-based train power transfer systems have high maintenance costs and safety issues and cause noise and additional aerodynamic drag. Instead of the conventional system, a loosely coupled online wireless power transfer (WPT) system for a train is proposed in this paper. Th ...

AXICOM Latching Relays
... This design is being used for telecommunication and signal relays. The relays are polarized and use an internal magnet instead of mechanical springs to apply mechanical forces to the relay armature when no voltage is applied to the relay coil. For non-latching relays the magnets are magnetized in a ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
