| Abstract: | The main magnetic properties of the new developing Fe73.2Cu0.8Nb2V1.5Si11.5B11 nanocrystalline soft magnetic alloy is reported in this paper,which is 0 8104, B s=1.40T, P 0.5/20k19W/kg, P 0.5/50k90W/kg.With the parameters of e(1k) and P 0.5/20k,the temperature-stability of this alloy has been studied and it shows that comparing with 25,when temperature is -50 or +150,the relative changing-rate of the properties of this alloy is not beyond 5%.The application studies in the area of power electronic technology such as medium-high frequency power supplies,sensor,inductor and so on is introduced in this paper. |
