"CHIPS: Shaped-foil inductor could reduce size, cost for energy applications"

Inductors smooth current flow in voltage conversion applications, but add significant bulk and cost, especially to high power applications like hybrid vehicles. Now a shaped-foil inductor design is offering loss reductions as high as 50 percent compared to conventional inductors. The shaped-foil design was invented at Dartmouth College (Hanover, N.H.) and has been licensed to West Coast Magnetics (Stockton, Calif.).
