Hi,
I wanted to know how you can derive the soft limiter maximum and minimum points where it changes in slope as part of the voltage at Va and Vb.
In the attached graph, the derivation would be:
Va = Vref*(R4/R3) - Vd1*(1+R4/R2)
Vb = Vref*(R6/R5) + Vd2*(1+R6/R5)
where Vd1 and Vd2 is the voltage drop due to the diode.
Thanks.
