Abstract

-A Mn-Zn ferrite with fine grain size and low core loss at 0.5 to 2 MHz was developed, and a conductor-embedded-type planar transformer was made using the developed ferrite. The Bm-f value in the loss level of 400k W m"3 of the developed ferrite at f=lMHz is 2.2 times larger than that of the commercial ferrite. The efficiency and the output power of the conductor-embedded-type planar transformer were 91% and 1.8W, respectively. i
