Abstract: | This article discusses a new experimental way to measure the I-V characteristic curve of photovoltaic (PV) generators based on DC-DC converters. The obtained results show that the classical buck and boost converters are not capable of reproducing the whole I-V curve of PV generators and that the single-ended primary inductance converter (SEPIC) is optimal for this application. We propose a method based on SEPIC converters in parallel connection, operating in an interleaved mode. This method gives advantages with respect to the use of conventional methods. |
