Abstract : Ever-rising concerns on climatic changes and accelerated depletion of fossil fuels raised by the world needs an immediate action to accelerate the clean energy generation with available renewable energy resources (RES). Hence the involvement of alternative energy sources is growing at a faster pace. There are many renewable sources like solar, wind, hydro, geothermal, etc but only a few pertain the adequate potential. Alternative from solar energy for daily needs is one such platform which has immense potential and is universally accessible with least environmental effects. Solar photovoltaic (PV) is a promising solution for extracting solar energy. Along with the growing dependence, there is a thriving need for the development and advancement of the technologies presently on the deck. This is a platform which needs the ultimate attention in the current scenario. This paper focuses on the analysis of the available trends in inverter technology for grid tied solar PV systems to make it fast and reliable thereby reducing losses and mitigating harmonics. Some of the inverter control strategies will be discussed here to improve the overall efficiency of the system by modifying synchronous reference frame (SRF) technique. The adaptive dc link technology is being focussed in all the topologies as it helps in reducing the switching losses in the system.
