@sribasu Just to be clear, you want hysteresis to avoid the chattering. Lacking it is the reason for the chattering behavior.

@EdinFifić Thanks for taking a moment. I'm of two minds. The first is to completely embrace your arrangement as a very good teaching stair-step. The output is essentially useless faced with the usual...

I'm not entirely clear on this. Are you asking about a case where you want the source-free evolution of the voltage across this Ztotal given initial conditions for the capacitor and inductor? Or is...

How mathy of an answer do you want? Closed solution? And can it be limited to the six parts on the left side of your redrawn schematic?

@eccentricOrange I broadly agree with others saying you won't find a single defined standard here. That doesn't mean there aren't good designs to learn from and use to help improve what you already do....

Zachary, this kind of problem is usually handled with either nodal or mesh analysis, especially so due to the dependent sources. Have you experience there?
