【Abstract】 High power inverter cores made of nanocrystalline FeNbCuSiB alloy are introduced. The new cores show excellent properties, such as low core loss and high permeability. The heat produced by the core can easily be sent out by new cases. The new cores can be applied in various high frequency and power main transformers under 20～100kHz.更多还原
