基于光伏电池特性的逆变器参数设计

Design of the Parameters of Inverter Based on PV Cell Characteristic

根据电池电压-电流(V-I)的工作特性曲线来选择主回路中的电容及电感参数,既满足了性能指标要求,又可以合理地降低成本。运用电池板在不同光照、不同温度下功率和电压的关系,得出电容和电感的参数计算曲线,从而确定了电容和电感的合理参数值。此参数选择方法为实际的光伏逆变器工程设计提供了依据。

According to the V-I operating characteristics curve of cells to select the main circuit capacitance and inductance parameters, both can meet the performance requirements, but it is reasonable to reduce costs.Using power and voltage relationship of solar cells groups in different light under different temperatures, the calculated curve of capacitance and inductance parameters are derived,thus reasonable parameter values of capacitance and inductance are determined. This parameter selection method provides a basis for the actual photovoltaic inverter engineering design.
