MPPT - The working principle of maximum power point tracking is that the microprocessor periodically adjusts the duty ratio D of the PWM periodically to change the output current of the solar cell during a specified period, thereby causing the output voltage of the solar cell to change. The solar cell output voltage and output current are calculated, and the output power of the solar cell array is calculated, and then the position of the maximum power point is found according to the maximum power point tracking strategy.
