Nonlinear Effects for Inductors
Scott,

Saturation, the nonlinearity of inductance with current, is at least able to be regarded as a quasistatic (0+ Hz) effect, but winding resistance with frequency is also nonlinear, and increases with number of winding layers and wire size. It cannot be ignored except for circuits exciting the inductor with only low frequencies because it has a major effect on resistance.

Eddy-current and saturation effects - both nonlinear, and without them, inductor modeling would be much simpler!

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the emergence of solid state electronics as well as the phasing out of mechanical components in favor of electrical components.
It’s been a while since I addressed Bode plots as a main subject so I thought this would be a good opportunity for a refresher on a very basic stability tool
Although they are a simple device, diodes do have a number of traits to consider. These traits are often application dependent.
Recently, I found that the area of hysteretic control offered me a change to look in a new area that simplifies control loop design to a degree
