I was reading about grid tie inverters and how they work, but something I didn't understand is how they feed the greed with current. So I began reading several forums about it , and while some say that the output voltage of your inverter has to be a bit higher than the greed voltage, others say that the inverter acts as a current source. I didn't quite understand how that would work, but now that I think about it, it seems right. While using mosfets as switches you're turning them from cut-off to saturation, and as far as I understand, mosfets in saturation mode act as current sources. Am i right thinking that this is how it works? Or is there another mechanism out there that makes sure a grid tie inverter feeds current to the source?
Thank you.
