A new theory could help build future superconducting alternating-current fault-current limiters for electricity transmission and distribution systems. The work identifies design strategies that ...

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

THE second edition of this text-book is a creditable effort on the part of the author to cover, in a single volume of 730 pages, the extensive field embracing the theory and applications of direct ...

In a hybrid and other electric vehicles (EVs), two key elements work together to manage power and recharge the circuits. Here is how these critical components—the inverter and converter—work ...
