Generating I-V Curves with the Solar Array Simulator
应用文章
Keysight Technologies, Inc.’s family of solar array simulators, including the E435XB Series and E4360A modular solar array simulator mainframe, can be programmed to simulate a wide range of solar array performances. Three methods for generating an I-V curve are available: using table mode to enter I-V data pairs and using parametric values in SAS and list modes.
Two major formats for parametrically programming solar array simulators using equation-based I-V curve generation are currently in use. The parameters required by the equipment using either format are not directly compatible with the other, and the conversion from one format to the other is not mathematically tenable since no closed-form solutions for the equations exist. However, values for Voc, Vmp, Imp, and Isc, the Keysight format, can be obtained from the values for Voc, Isc, N, and Rs through the application of an iterative solution technique. This application note provides the methodology.
