Renewable energy resources like sun, wind, biomass, geothermal, etc., are abundant in nature, toxic-free, and eco-friendly. Those are sufficient to meet the energy demands which are required by the consumers. Solar photovoltaic energy is one of the clean renewable energies among others. A solar photovoltaic system is gaining popularity as compared to other non-conventional sources because of the sufficient solar irradiation received by the earth. Moreover, the costs of PV modules have been declining. PV system has been included with PV panels, batteries, or any other storage devices as well as power electronic converters. Power electronic converter systems are the only choice to fulfill the requirements in the power system. Therefore, this work aims to discuss the power electronic converter technologies that can be used as interfaces and discuss their merits and demerits. Power electronic converter technologies are used to convert the one form of energy to other energy or vary the energy range as per the load requirement

The Role of Power Electronics in the Field of Photovoltaic System: A Study

In upcoming years, energy generated through solar which plays a vital role in power generation has gained importance. The key problem in solar generation is to extract maximum power from solar photovoltaic module at all weather conditions. But due to partial shading conditions caused by bird droppings, soil accumulation and cloud formation, it leads to multiple local peaks making the tracking complex. Since, PSO has gained its significant popularity in the area, maximum power point tracking under partial shading conditions. Analysis of PSO and variants to observe their adaptability for different irradiance conditions such as uniform irradiance, strong shading and weak shading. In this article, a comparative study has been presented for different variants of PSO. The results are analysed based on power oscillation and catching peak through MATLAB simulations.
