Chakravarty, Saurabh (author)Photovoltaic (PV) modules have considerable difficulty when exposed to shading since even partial blockages can significantly reduce energy production. To make the PV module shade-resilience, sub-module maximum power point tracking(MPPT) can be done for each string in the module. One way of doing it is by using converters at the sub-module level...master thesis 2023
