Research on Maximum Power Point Tracking Control Based on the Low Power Photovoltaic Grid-connected Inverter

摘要：

The grid-connected photovoltaic system is the trend of the photovoltaic system .On the basis of the analysis of the equal circuit about the solar cell and the character curve, for the two-stage gridconnected inverter, provide the maximum power point tracking(MPPT) methods, and design a photovoltaic inverter based on the DSP which controls the maximum power point. Trough testing the old designed inverter has many unstable questions when tracking the maximum power point, after experiments and analysis .providing an improving way. The experiment proves the improved inverter runs stably and reliably.
