West Coast Magnetics announced a proprietary inductor technology that achieves an improvement in cost and efficiency over existing inductor technology. It 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 percent to 50 percent compared to conventional wire wound devices are typical. The technology fits with the newer classes of silicon devices such as IGBTs designed to operate at current levels of 100A and up and at frequencies over 10 Khz.
