Abstract Based on the particle grading theory, the second-level Fe-Si-Al particles of different sizes were mixed with the first-level Fe-Si-Al particles and third-level carbonyl-iron particles in a fixed proportion to prepare different graded powder cores. The effects of the second-level particle size on the density, the volume resistivity, the effective permeability, the DC-bias performance and the core loss of graded powder cores were studied. It was found that the size of the second-level particle influences the magnetic properties of powder core through two ways. One is changing the core's porosity, which directly determines the core's density. The other is adjusting the distribution of different particles, which mainly affects the core's resistivity. Suitable second-level particle size is helpful for increasing both the core's density and the volume resistivity. It decreases the structural demagnetizing field and the eddy current within the core and thus results in the improvement of the core's magnetic properties. This study provides a possible reference for the application of particle grading in the field of soft magnetic powder core and introduces new ideas for the improvement of the performance for soft magnetic powder core.

Key words： soft magnetic powder core particle grading second-level particle porosity magnetic property
