What are the dynamic magnetic properties of a C-type amorphous core?
Based on a novel designed tester, the dynamic magnetic properties of the C-type amorphous (AMCC025) core and nanocrystalline (F3CC0125) core with different lengths of the air gaps are measured and analyzed when the cores are excited at different frequencies.
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.
Do frequency-dependent losses increase with flux density?
In particular, the frequency-dependent losses decrease to a minimum value and then increase with the increase in flux density accordingly. The modified loss model and results would be beneficial to the design of high-frequency inductors and transformer cores.
Do amorphous materials have a good mixture of coercivity and saturation flux density?
The chart in Figure 2 shows that amorphous materials have a good mixture of coercivity and saturation flux density. The composition of amorphous materials consists of trace elements such as Cobalt and Iron together with mixtures of Silicon and other elements such as Niobium.
How to correct amorphous material with domain wall movement magnetization?
The core losses of amorphous material with domain wall movement magnetization are high and are dominated by anomalous losses. This is corrected by applying magnetic annealing (up to 5T magnetic field) in a transverse direction to the easy axis at diferent temperatures starting from 500 °C.
Why is amorphous Wire better than NiFe?
The amorphous material had a strong advantage over NiFe when it came to form factor reduction as fewer turns would be needed, and it would be more eficient as thicker wire with lower copper losses could be introduced.
