Performance comparison of MPPT techniques using Cuk converter for photovoltaic energy conversion system

This paper deals with performance analysis and comparison of photovoltaic (PV) energy conversion system for two different maximum power point tracking (MPPT) techniques. A CUK converter is used in the PV system to implement the MPPT controller. Two different MPPT controllers are designed to locate the maximum power point: Perturb & Observe and Fuzzy logic based. To evaluate and compare the performances of the designed MPPT controllers PV system is operated with different environmental conditions.
