Feedback loop switch on/off W1 to keep VLOAD = Vref±δV. It switchs off W1 and inject current when VBatt goes down. When Battery is charged W1 is switched on and no current flows into VLOAD
X1 adds hysteresis
X3 and V1 models real world battery.
X2 is a linear (a/1+s*τ)
Circuit is unstable. I need to know how to analyze such topology. VBatt and C1 Parasit elements matter regarding stability.
Adding a lead in X2 improves stability (present circuit only has lags, too much lag of course) but I need the math o show how the intuitive works, trade-off, limitations etc.
I don't now the name of this kind of regulator, to know it would allow search in the web.
