Comparison of DC-DC Converters for Photo-Voltaic Application

Abstract:

Electricity demand is a major concern in the world today. To meet this demand, a number of natural sources are used for electricity production. The produced electrical energy from these natural sources will be given to consumers after going through a lot of conversion stages. So losses mostly occur in these conversion stages. In this paper the four existing converters CUK, SEPIC, Self-lift CUK and Self-lift SEPIC performances are separately compared and analyzed with each other. The voltage-lift (VL) technique is a popular method that is widely applied in electronic circuit design. This technique overcomes the effects of parasitic elements and increases the output voltage effectively along with high power efficiency and high power density with a simple structure. The operating principles of these converters are discussed and Simulation results are provided to verify and compare the feasibility of each systemwith solar photo-voltaic panel incorporated maximum power point tracking (MPPT).
