West Coast Magnetics' 308 series power inductors deliver very high performance in a small, light, low cost package. They have been designed to handle very high DC currents and high AC ripple currents from 60Hz up to 500kHz.

These inductors offer exceptional reliability with an operating temperature rating of 200C and they can be ordered using West Coast Magnetics' SHAPED FOIL TECHNOLOGY^TM.

POWER MAGNETICS DESIGN SEMINAR

West Coast Magnetics will be offering a ½ day course in magnetics design for power electronics beginning in the first quarter of 2008. This course will emphasize a practical approach to design of power magnetics and is designed for engineers who are designing magnetics for the first time. Topics covered will include switch-mode transformer design, common mode choke design, boost inductor design and current sense transformer design. Litz wire, solid wire and foil windings will also be covered as well as an overview of core material types commonly used in power electronics..

February 2007 : Announcing a new inductor technology

West Coast Magnetics is pleased announce a new inductor technology which achieves a major improvement in cost and efficiency over existing inductor technology. This new technology combines the low DC resistance of a foil wound inductor with the low AC resistance of a litz wire wound inductor. For high current, high ripple applications at frequencies of 10 kHz and up loss reductions in the range of 25% to 50% compared to conventional wire wound devices are typical. The technology fits very well with the newer classes of silicon devices such as IGBTs designed to operate at current levels of 100 amps and up and at frequencies over 10 Khz.

The technology was patented by the Thayer School of Engineering at Dartmouth College and is under exclusive license by West Coast Magnetics. West Coast Magnetics has worked closely with Dartmouth to develop the technology so that it is ready for commercial use.

Weyman Lundquist, President of West Coast Magnetics, summarized the benefits

"Very simply, this new technology, will lead to the use of smaller and lower cost inductors for a host of very important developing power electronic applications in the energy field. Wind energy, hybrid vehicles, solar energy and many other environmentally friendly energy technologies rely on continued improvements in power electronics, and power inductors are one of the main building blocks of virtually all power electronic equipment."

West Coast Magnetics has completed a market forecast which concludes that the global market for inductors of the class which stand to benefit from this new technology is forecasted to exceed $1 billion by 2010, and reach $2.5 billion by 2015. The breakdown in 2015 is $832 million for hybrid vehicles (including heavy commercial, passenger, and light utility), $812 million for solar, wind and other power generation and transmission applications, $464 million for large uninterruptible power supplies, and $359 for other categories.

If the technology is extended into lower power applications such as personal computers, desktop electronic equipment and handheld devices the total global market will exceed $5 billion in 2015.
