Differential-mode EMI currents flow only in the functional unit's active input and return path, and are isolated from the system ground or earth-return path. By understanding where EMI conduction ...

Inductors control electric current by using magnetic fields to resist sudden changes. This video explains how a simple coil ...

Inductor selection for very-low-power or very-high-power energy conversion is not as simple a process as it is for the majority of power-supply designs. Off-the-shelf inductors from major suppliers ...

Various switchmode power supply topologies use inductors for energy storage. The photos, below, show examples of an unshielded (left) and shielded (right) power inductor. The necessary inductance ...
