Abstract :
This paper describes a method of Maximum Power Point Tracking(MPPT) with MCU controlling system in grid-connected photovoltaic generation system, especially introduces the techniques and principles of DC-DC conversion. The MPPT is implemented with a Buck-Boost DC-DC converted circuit topology. The system is simple with good response speed, and the controlling method is flexible with software and hardware combined. And the efficiency of photovoltaic power generation is improved apparently with the method in grid-connected photovoltaic system.
