AN IMPROVED VOLTAGE-BASED MAXIMUM POWER POINT TRACKINGMETHOD FOR PHOTOVOLTAIC PANELS

摘要

The paper presents an improved maximum power point tracking (MPPT) scheme forphotovoltaic panels which is more accurate than some of the methods reported in literature. Theproposed scheme includes temperature compensation and demonstrates the operation for abattery charging system with a buck-boost converter. The development of the control law,implementation of the control scheme, and experimental results are presented.
