贮能电感器和变压器是开关电源中的关键器件,提高开关频率可使之小型化,电源的功率密度(功率/体积)可得到提高,文章介绍其研究发展状况,并比较说明各种新型高频磁性元件的特点。
Energy-saving inductors and transformers are the key components in the switching power supply. It can be miniaturized by increasing the switching frequency and the power density (power / volume) of the power supply can be improved. The article introduces its research and development status and compares various new-type highs Frequency magnetic components of the characteristics.
