Magnetic cores for power supply inductors require careful selection because of the important role they play. An inductor core must be able to retain inductance with dc bias and handle any ripple ...

If, on the other hand, you design for the much larger value of inductance required at light load, your inductor will be overspecified for the nominal load and will be too large physically. One ...

One of the best tools in the engineer’s lightning protection toolbox is a tried, true and frequently underutilized friend, the ferrite toroid. The principle is quite simple. If you have two (or more) ...
