Energy Yield Assessment Methodology for Photovoltaic Microinverters

Autor: Dmitri Vinnikov, Samir Kouro, Kosenko Roman, Oleksandr Korkh, Andrii Chub

Publikováno v: 2019 IEEE 15th Brazilian Power Electronics Conference and 5th IEEE Southern Power Electronics Conference (COBEP/SPEC).

Two-stage photovoltaic (PV) microinverters with a buck-boost front-end converter can provide unparalleled performance under shading conditions. However, their efficiency curve is not monotonic across the input voltage range. As a result, it is hard t
