摘要：

A study of the maximum power point trackers using a switching-frequency modulation scheme (SFMS) for photovoltaic panels is presented; a dc/dc converter is used Method of locating the maximum power point (MPP) is based on injecting a small-signal sinusoidal perturbation into the switching frequency of the converter and comparing the ac component and the average value of the panel's terminal voltage. Apart from not requiring sophisticated computation of the panel power, this SFMS does not approximate the panel characteristics and can globally locate the MPP under wide irradiation conditions. Theoretical predictions will be verified with experimental results. Operating characteristics at steady state and in large-signal change of the solar irradiance (incident solar radiation) level will be studied.
