Local maxima in the measured power curve of a photovoltaic (PV) panel, called traps, are caused by switching transients and other deterministic phenomena in PV power converters. Traps exist even in the absence of shading, and degrade the performance of perturb and observe (PO) maximum power point trackers. A generalized PO (GPO) algorithm is proposed which eliminates this degradation. PO/GPO algorithms...
