摘要：An improved analysis of maximum power point tracking with incremental conductance of solarphotovoltaic array under partial shaded condition is proposed in this paper. To improve the extracted maximum powerfrom a PV array during partial shading conditions the switched photovoltaic (PV) approach is proposed in this paper. Inthis paper we use the IC techinque, it is used to track the maximum power point of the PV source. MPPT can minimizethe system cost and maximize the array efficiency. The proposed system is simple and cost effective. However,compared to other existing solutions it may provide lower power enhancement, which makes it more suitable fordomestic applications. This research was aimed to explore the performance of a maximum power point tracking systemwhich implements Incremental Conductance (IC) method. The IC algorithm was designed to control the duty cycle ofBuck Boost converter and to ensure the MPPT work at its maximum efficiency. The comparison has been made forseries and parallel connected solar photovoltaic modules under partial shading condition and it is inferred that parallelconnections must be dominant under partial shading condition. I-V characteristics of Parallel array shows that Isc ofparallel array is sum of short circuit current of all modules connected in parallel. Simulation results show thepossibility of enhancing the PV array’s extracted output power during partial shading with the proposed system.
