Powder cores are a small but important family of materials that bridge the gap between low frequency strip cores and high frequency ferrite cores. Their unique combination of high saturation flux, relatively low core loss and distributed airgap
Because powder cores have properties that are at the same time both similar to and different from ferrite, we can take advantage of the differences to make chokes that take up less space and cost less. That applies to many choke types, including pfc chokes,
