    variable power source (like solar panel) component in proteus required

    i want library for a solar panel in proteus or a variable power supply which gives voltage and current variation during simulation.kindly help

    Re: variable power source (like solar panel) component in proteus required

    A PV panel puts out high A at low V, or low A at high V. It depends on how much you load it.

    Example:
    0.1 A @ 20V (2W, light load)
    4 A @ 0.5 V (2W, heavy load)

    Maximum power transfer is at a middle point. Example, 2A @ 12V (24W, medium load).

    This is difficult behavior to model in a component. I have not seen a simple circuit which is able to mimic it.

    Thanks for the reply,i thought there is some component for it just like i have downloaded microphone's library the other day.
    i would be very thankful if you can find a variable power supply for proteus as the one attached (image)Click image for larger version.

    To simulate a PV panel, I believe it's okay to use a DC source and a resistor in series.

    The scope traces agree pretty much with real tests I did on my PV panels, by attaching different value resistors.



    Notice you do not get maximum power at highest V or highest A.
    Rather it occurs at a middle point. It is where the load equals the panel's internal resistance. This is the principle of impedance matching.
