The microcontroller used in this project is the ATmega328 which is included in the Arduino Uno Rev3 board. The Arduino Uno has been used to upload a fuzzy logic C program where the program can optimise the power of the solar by controlling the duty cycle of MOSFET in boost converter according to the output voltage of the solar panel. The first input of the controller is the output voltage of solar panel. The second input is the reference voltage. The inputs for the fuzzy logic program are the error and change of error.
The calculations for these inputs have been written in methodology. The output of the controller and also fuzzy logic program is the PWM duty cycle for the MOSFET. Before connect the controller with solar panel and boost converter, it is connected with DC power supply for the input voltage and Digital Storage Oscilloscope (DSO) for checking the PWM output. The required debugging was done to see the final PWM output at DSO.
