Abstract –In photovoltaic (PV) systems, conventional energy conversion architectures are frequently compelled to choose between power generation and conversion efficiency. This work proposes an energy conversion scheme that, although converting just a small fraction of the total power generated, allows each PV element to function at its maximum power point (MPP). To achieve this, only the MPP current mismatch of a group of series-connected PV elements is supplied. Differential power processing improves overall conversion efficiency and provides solutions to issues caused by subpar MPPs (due to partial shading, damage, manufacturing tolerances, etc.). The analysis and comparison of different differential power processing architectures with Monte Carlo simulations. Distributed monitoring and protection are made possible by local control of the differential converters. System reliability has significantly increased overall, according to reliability analysis. simulations and experimental results exemplify the advantages of this strategy at the panel and subpanel levels, respectively, and are included.
