Abstract:
In photovoltaic (PV) systems connected to the AC power grid, traditional approaches employing series-connected PV panels with a single central converter often suffer from reduced efficiency and reliability due to partial shading or mismatch of PV cell characteristics. To address these challenges, the concept of differential power processing (DPP) converters has emerged, enabling independent maximum power point tracking (MPPT) of each PV panel while mitigating power loss under mismatched conditions. Various DPP system configurations are introduced and their advantages and trade-offs discussed. Additionally, recent research comparing bidirectional flyback and split-inductor boost converter topologies for PV-to-bus DPP systems is presented. Experimental results demonstrate a converter efficiency improvement of 14.7% over traditional flyback converters, offering promising avenues for enhancing the efficiency and reliability of PV systems.
