Photovoltaic (PV) energy is one of the most important energy resources since it is clean, pollution free, and endless. Maximum Power Point Tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic output power, irrespective the variations of temperature and radiation conditions. This paper presents a comparison between \u0106uk and SEPIC converter in maximum power point tracking (MPPT) of photovoltaic (PV) system. In the paper, advantages and disadvantages of both converters are described. Incremental conductance control method has been used as maximum power point tracking (MPPT) algorithm. The two converters and MPPT algorithm were modelled using MATLAB\/Simulink software for simulation. Simulation results show that both \u0106uk and SEPIC converters can track the maximum power point with some minor variations. <\/p>\r\n","references":"[1]\tAeronautics and Space Administration, (NASA-CR-149364) National Solar Cell Array Design Handbook, Vol.1, Jet Propulsion Lab, 1976.\r\n[2]\tK.
