ارزیابی مواد مغناطیسی برای کاربردهای قدرت با فرکانس بسیار بالا

چکیده انگلیسی مقاله:
Abstract- This paper investigates the loss characteristics of RF magnetic materials for power conversion applications in the 10 to 100 MHz range. A measurement method is proposed that provides a direct measurement of an inductor quality factor Q L as a function of inductor current at RF frequencies, and enables indirect calculation of core loss as a function of ?ux density. Possible sources of error in measurement and calculation are evaluated and addressed. The proposed method is used to identify loss characteristics of several commercial RF magnetic-core materials. The loss characteristics of these materials, which have not previously been available, are illustrated and compared in tables and ?gures. The use of the method and data is demonstrated in the design of a magnetic-core inductor, which is applied in a 30-MHz inverter. The results of this paper are thus useful for the design of magnetic components for very high frequency applications.
