MPPT code

Hi i am doing project in PV mppt, i want to multiply 2 analog signal (p1 = x1 * y1 ) and with a delay i need to compare those two power (p1 and p2) and need to vary the pwm output....
i am not using battery , (using boost converter)

Good to know, thanks.

Go ahead - you don't need permission.

If you are not using a battery, what purpose is served by varying the PWM rate, ie what is the purpose of the project.
