Abstract
 In this paper the performance of Nanocrystalline material in comparison with ferrite is evaluated for a high frequency high power transformer core application. The major advantage of Nanocrystalline material over ferrite is its ability to go for higher design flux densities. However, this is limited with increased losses occurring with the increase of operating frequency. The situation is studied for a 40kW, 20 kHz application. Samples of both versions are developed and a performance evaluation is made on the application. Based on the practical outcome a comparison is made in terms of power density per physical parameters such as weight and volume. The cost and manufacturability are also discussed.
