LECTURE 33 Inductor Design

An inductor is a device whose purpose is to store and release energy. A filter inductor uses this capability to smooth the current through it and a two-turn flyback inductor employs this energy storage in the flyback converter in-between the pulsed current inputs. The high µ core allows us to achieve a large value of L = µN2A c/l c with small
