Grid-tied Photovoltaic power electronics converters: Overview, analysis, challenges and future trends

Author(s): Faramarz Faraji

Statement of the Problem: Renewable energy is progressively deemed necessary for fulfilling the current and upcoming energy demands. Amongst different renewable energies, solar photovoltaic (PV) is one of the cleanest, unlimited, emission-free, readily, reliable and widely available renewable energy resources. Grid-tied PV systems account for 99% of the whole established capacitance in comparison with 1% of the standalone systems. Grid-tied PV systems are generally categorized into two types, the galvanic isolation and non-isolation/transformerless systems, the latter having some advantages over the former, e.g. small size, weight, low cost and high efficiency. However, leakage current problem is one of the most important challenges in transformerless system which may cause some problems. Power electronics converter topologies play a significant role in restriction of this current. Therefore, a variety of state-of-the-art converter topologies with the ability to overcome this issue are reviewed in this work. Then possible improvements are investigated and proposed for several important aspects such as efficiency, reliability, power quality, cost, weight, velum, and leakage current problem.
