Solar PV Curve Genorator

[House91320]

I need a a power supply that will simulate the pv curve of a solar cell, dose anyone know of a good circuit to do this?

Depends on what you need, but a constant current source shunted by a diode is a pretty good model.

That's what was thinking thank you.

Depends on what you're trying to do with it. Obviously implementing the single diode model as a CC across a diode doesn't shift much in its characteristics (other than adjusting the current of course.), that may or may not be of any significance to you.

If you want it to match a certain cell a bit more closely you can easily tune the slopes of the IV curve by adding in series and parallel resistance like the single diode model has.
