Combining Solar and Wind

Altair Forum User

I am designing a system to combine solar and wind. I am having issues with the output… Depending on which system has more output it will affect the output of the other. Any suggestion on what I'm missing? I have the output of the two sources attached to the input of a DC motor.

If the output voltages of the wind system and the Solar system are not equal you will get circulating currents.

For example if the Solar module has an output voltage greater than the output voltage of your wind generator, the wind generator will act as a motor rather than a generator. You need to put in systems to control the voltage on the outputs of you wind and solar stages so that they are equal.
