Comparison of a two-phase interleaved boost converter and flyback converter

A big majority of electricity energy is generated from naturel sources such as coal, petroleum etc. in all over the world. The reserve of this sources are decreasing. However, the demand of electricity is increasing day by day. The researchers head for alternative energy sources such as biomass, geothermal, marine energies, hydropower, wind and solar. The most important of these is the solar energy. The studies about solar energy are increased in recent years. This study deals with the design and analysis of different converter topologies which are two phase interleaved boost converter and flyback converter in terms of structure, efficiency. Each system is consists of a photovoltaic (PV) module, converter topology and Maximum Power Point Tracking (MPPT) algorithm. The MPPT algorithm is necessary to acquire maximum power from the PV module. The power capacity of each system is 295 W and the input voltage of converters are around 54 V. While the output voltage of two-phase interleaved boost converter is 232 V, the output voltage of flyback converter is 238 V. In this study, it is determined that the efficiency of flyback converter is better than the two-phase interleaved boost converter
