摘要

I-V曲线是一个重要的参数，因为它包含了光伏组件的特性。它显示了由于外部变化而在模块中发生的情况。本文提出了一种在部分遮阳条件下，用反向电压跟踪光伏曲线的方法。此外，还提到了旁路二极管的作用。最后，对有阴影模块和无阴影模块的曲线以及并联电阻效果进行了比较。

Method to trace the photovoltaic characteristic curve with reverse voltage for shading conditions

The I-V curve is an important parameter, because it contains the PV module characteristics. It shows what happens in the module due to external variations. This paper presents a method to trace the photovoltaic curves with reverse voltage under partial shading conditions. In addition, it mentions the effects of the bypass diode. Lastly, it makes comparisons between curves of shaded and unshaded modules and the shunt resistance effect.
