Research of Photovoltaic Charging System with Maximum Power Point Tracking based on DSP

摘要：

According to the output characteristics of photovoltaic (PV) array and battery charging characteristics, this article used DSP to design a PV charging system with maximum power point tracking (MPPT) , and the three-state charging method was implemented on it. The incremental conductance (INC) algorithm was applied in fast-charge stage to track maximum power point. PI regulator algorithm was exploited to realize constant voltage charge in the stage of overcharge and float-charge, and the charge voltage was compensated by the sampling temperature. Experimental and simulation results indicated that this method can be used to improve the energy efficiency of PV cell, and extend the lifetime of battery.
