Hi,
I am about to design a MPPT buck controller with a PIC micro controller. I want to implement Incremental Conductance algorithm.
My question is what current value we have to use for the MPPT calculation? Because input current for the buck is pulsating (i.e. it a trapezoidal wave from in CCM or triangular in DCM ).
I think using average current value or RMS value of the wave form( hopping they will come close on doing math, but at this time I didn't do the math!) makes sense. Because all that we care is power out put from the solar panel.
My question also applies to voltage wave form, because I think the voltage from the panel will vary as the converter draws current from the panel.This is only my guess ( I didn't build the prototype yet).
I hope somebody would have successfully implemented the MPPT buck converter. Please share the ideas.
Thank you.
