Скачать или смотреть Application and Design of Magnetic Devices for High-Frequency Power Electronics Circuits

Magnetic components like inductors and transformers are essential parts of power electronic circuits. They are used for galvanic isolation, voltage transformation, filters, etc. The size and overall dimensions of the circuit depend on how efficiently these components are designed and manufactured. Main requirements in designing these components are low losses and high power density with compact dimensions. Selection of core geometry and its magnetic material with desirable saturation magnetic flux density is the most important design step. Hysteresis, eddy and anomalous components make the total magnetic loss. Skin and proximity losses in windings can become critical at high frequencies. To overcome these challenges, relevant electromagnetic concepts including theory of eddy currents need to be properly understood. This talk focuses on such fundamental aspects in addition to design of magnetic circuits and coils for high frequency applications. Finally, steps in design of a high frequency inductor are elaborated.
