Which type of Powder Core?
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, output chokes and differential emc chokes. The difference is that they not only have a higher saturation, but it is also a “soft” saturation.
In this TECH TIP, I shall give a first example of the sort of size reductions that can be achieved...
