Examination of MPPT Algorithm on Three Step DC-DC Converter

Abstract

As a non-conventional energy source, PV installations are being increasingly applied in many applications. Still, a severe challenge in using PV sources is to grab its nonlinear output characteristics, which change with temperature and solar insolation. Photovoltaic (PV) array appearance is suffering from a temperature, solar insolation and array configuration. The benefit of using a Solar Photovoltaic System (SPV) is low cost, easy maintenance, low greenhouse gas emission etc. Maximum point tracker participates a vital part in the SPV system for enhancing efficiency. Hill-climbing technique based MPPT controller enabled with three steps DC-DC converter is applied to extract power from solar PV module and transfer to load. The single diode PV model is studied and the simulation results of MPPT with PV fed three steps DC-DC converter is analyzed.
