| Abstract: | Because of low conversion efficiency of photovoltaic cells, how to effectively improve the utilization rate of photovoltaic is vital to solar photovoltaic system. In this paper, a common engineering model and its Boost converter are established. And an improved perturbation observation method is used to control the boost converter to realize the PV maximum power point tracking (MPPT). Then the implementation strategy is expounded and verified through the simulation. The results show that the proposed method can track the maximum power point accurately and achieve high energy conversion efficiency with the change of temperature and sunlight. |
