Shade-tolerant photovoltaic microinverter with time adaptive seamless P-V curve sweep MPPT

This paper proposes a novel approach to photovoltaic (PV) module level power electronics (MLPE). Functionally, it is a hybrid of PV power optimizer and microinverter with such key features as shade-tolerant (or global) maximum power point tracking (MPPT), galvanic isolation, direct AC connectivity, PV module level monitoring and safety cut-off, flexibility of installation and PV power system sizing. Focus is on the realization of the...
