In order to ensure that the photovoltaic (PV) array always works at the global maximum point of
power to increase the system’s overall efficiency, this paper leads the study on maximum power point tracking
(MPPT) in redundant load mode. A new control system is designed by combining the redundant electronic load
module, embedded controller, supportive capacitor and boost circuit. The system adjusts duty ratio of boost
circuit dynamically based on the maximum power point parameter provided by redundant load unit in order
to realize MPPT. An experiment shows that no matter whether system is under an even illumination or partly
perturbed by shadow, this method can find the exact maximum power point.
