Hello I am making an ANN based MPPT using the following schematic. After generating Vmpp I dont understand how or what goes on in the Calculation block that eventually produces a PWM ? Is there a PI controller in it or a duty cycle formula ?

Hello Haider,

Firstly, how did you combine the Step and Ramp sources together?

Thank you.

I think the ANN will give a new value of the Vmpp at every instant and then the calculation block will set the duty cycle in accordance with the set value by the ANN and hence at every instant the DC-DC Converter will operate on that point so to get max power. I'm also implementing the same 6KW system for varying irradiance conditions but there are a lot of trouble in the implementation of the ANN. Can u help me for it? Any guideness how You implement the ANN? You can contact me at pmtaimoor786@gmail.com. I'll be waiting for your response. Thanks
