The working principle of MPPT is: within a specified period, the microprocessor actively adjusts the duty cycle D of the PWM periodically to change the output current of the solar cell, thereby arching the output voltage of the solar cell, detecting the output voltage of the solar cell and Output current, calculate the output power of the solar array, and then find the position of the maximum power point according to the maximum power point tracking strategy.
Characteristics of solar array
The output characteristic of the solar cell array is different from that of the standard DC power supply. The output curve of the solar cell is a smooth curve, and the output curve of the standard power supply is rectangular.
The main parameters for determining the output curve of solar cells are: Voc open circuit voltage, LSC short-circuit current and Pmax peak power.
