Analysing efficiency of DC-DC converters joined to PV system run by intelligent controller

Generating electricity using Photovoltaic Cells (PVCs) is a challenging task as photovoltic array hinges on solar irradiance, temperature and photovoltic Cells voltage (PVCsV). A maximum power point traker is indispensible to mitigate this challenging task. Developing efficient PV arrays strongly stresess to fix the operating point at MPP. In this paper, MPPT supported by Buck and Boost topologies are designed run by Intelligent Controller(IC). The intelligent controller is governed by improved perturb and obserb algorithm (IPOA). This algorithm helps the Boost converter always fix the operating point at maximum value regardless of atmospheric circumstances. Hence Boost converter exhibits better efficiency than Buck converter. A hardware model is used and laboratory testing of this model is performed.
