The basic principles of MPPT are as follows:
The basic process is to calculate the power difference and the voltage difference for the input signal.
Then, the judgment is made according to the product of the power difference and the voltage difference.
Then the specific calculation iterative formula for not long is:
Note that some documents use P and rotational speed W for judgment, and some documents use P and U for judgment. Here I use P and U for judgment, and the effect is better than the joint judgment of P and W.
