高周波POL電源の研究動向と磁性体装荷の展望

抄録

This paper describes the trends on research and development of the switching power supplies for point-of-load, whose switching frequencies are increased to make them smaller. Examples of small power magnetic devices and switching power supplies in which those magnetic devices are mounted will be introduced. In addition, it details the recent research trends of ultra-high frequency and ultra-compact switching power supplies, the latest efforts and prospects for novel high-frequency magnetic materials having granular structure and their applications as the high-frequency power magnetic devices for those power supplies.
