A review on power electronic converters suitable for renewable energy sources

At present, power electronics advancements on renewable energy sources are mainly lying on converters and inverters (i.e.) moderators. The power electronic modules play a vital role in handling generation, transmission, distribution and consumer end appliances. Due to the lack of familiarity on the power electronic modules the researchers experience the complexity in choosing appropriate power electronic modules for standalone renewable energy sources like Photovoltaic panels, wind turbines etc. The improper selection of power modules leads to deteriorating the efficiency of the system and detriment of the equipments too. There is a discussion on the usefulness of hybridization of renewable energy resources by taking into account of optimum utilization and compensation of the investment done on the sources. So, choosing a suitable power module for the hybrid system further increases the complexity in choosing the appropriate power electronic modules. This proposed paper will emphasis on different power electronic converters that have been presented in the literature which are suitable for stand-alone and an array of renewable energy sources. In addition, it presents about different kinds of power converter topologies along with the technical requirements, control structures and boundaries. This paper also gives an insight on the evaluation of the existing converter topologies by considering the various parameters. Through which a suitable characterization of promising converter topology can be opted for either stand alone or hybrid renewable energy resources.
