Abstract
In order to improve the charging efficiency of photovoltaic system, the system controller takes the high-performance low-power Atmega 16 microcontroller as a core, changes the output voltage of Buck converter in real-time by adjusting the PWM duty cycle, and uses the MPPT control strategy of perturbation and observation method to achieve tracking of maximum power point of the photovoltaic power generation system. The MPPT algorithm was optimized to solve the problems of power oscillations and misjudg-ment probably caused by rapid perturbation during the tracking with perturbation and observation method. The real-time maximum power graph of the system is shown by a friendly man-machine interface. The testing results indicate that the method can ensure PV system to realize MPPT fast, steadily and accurately, and improve the charging efficiency.关键词
