Abstract :
A new experimental way to measure the I-V characteristic curve of a solar cell, module or photovoltaic generator by using Buck-Boost-Derived DC-DC converters is proposed. Theoretical analysis shows that the optimal topologies for this purpose are the SEPIC (Single-Ended Primary Inductance Converter) and Cuk converter. The advantages of this method are described, and experimental results show its usefulness.
