Trends in Electromagnetic & Magnetic Components

Author: Andrew Adams, ETAL Group

For many designers these magnetic and electromagnetic components are considered very "low tech". The reality is, however, that much technology and know-how is applied to designing and constructing these passive components: moving their capability inexorably forward. Technological developments - energy efficiency, weight minimisation, surface mounting and miniaturisation - have been major factors in driving advancements in this sector.

Selecting a Power Supply for Operation on Three-Phase Input

Author: David Buck, Market Development Manager, TDK-Lambda

Different countries around the globe have different regulations for supply voltages. It is important to be aware of each area's needs. Power supplies with a rated output of greater than 2,500W often require, or have an option for, a high voltage three phase AC input. A load of 3,000W, for example, operating from a single phase 230Vac input will consume 13A (3000W / 230V = 13A).
