I know this is an old post, but I have a similar query.
I have a voltage controlled current source that represents a V-I limiter for an audio amp. This gives me a typical limiting curve when Iout (y axis) is plotted against V control (x axis).
I would like to add a power rating curve representing the real life transistor max dissipation of 250 watts on the same graph as V against I. This is a simple I = 250 / V curve but not related to the DC analysis plot. Is it possible to add this, ideally from V = 14V to 70V? Dissipation below 14V exceeds the I limit of 17A and so is of no consequence, but the location of the curve in relation to the V - I limiter above 14 v is the critical factor to show.
The VCCS is set to 250mA/V and the control for that is a voltage generator that swings from 0 to 70V This is the x term.
The output is an ammeter in series with the VCCS and a 0.22 ohm resistor and is the y term
What I would like to show over the DC analysis graph is like this: (in basic, not sure what the syntax is for TINA)
for V = 14 to 70
i = 250 / V
next V
I can get this on an x/y plot using VP_1[1] (x) for the x term and 250/x+1 as the y term ( x+1 or the unit complains about division by 0) as the voltage swings from 0 to 70, but cannot superimpose this on the DC analysis for the main circuit.
Any help would be really useful.
