Amorphous high power inverter

What are amorphous magnetic cores?

Amorphous magnetic cores have superior magnetic characteristics, such as lower core loss, when compared with conventional crystalline magnetic materials. These cores can offer superior design alternative when uses as the core material in the following components:

Can amorphous material be used as a high frequency core?

More research is still needed to evaluate the amorphous material for alternative high frequency cores in high power converters or filters requiring low coercivity, good temperature stability and high permeability. “Bourns” is a registered trademark of Bourns, Inc. in the U.S. and other countries.

Why does amorphous magnetic metal have high permeability?

Amorphous magnetic metal has high permeability due to no crystalline magnetic anisotropy. Amorphous magnetic cores have superior magnetic characteristics, such as lower core loss, when compared with conventional crystalline magnetic materials.

Which amorphous materials are used in power inductor applications?

Nickel–iron alloy (NiFe) cores are commonly used in power inductor applications as they ofer good coercivity compared to ferrites and have higher flux densities as well. The chart in Figure 2 shows that amorphous materials have a good mixture of coercivity and saturation flux density.
