Study and Comparison of Various DC-DC Converters used in PV Systems

Abstract

The use of renewable energy sources (RES) has grown intensely during the several years. Due to its specific qualities, such as its environmental friendliness, silence, and lack of pollution, solar power has emerged as the most practical RES source. Because DC-DC converters are extensively utilized in a range of operations, the extraction of electric power paid special attention to them. The energy conversion efficiency, stability, and intermittent properties of photovoltaic (PV) systems are typically lower. The biggest electricity Point Tracking (MPPT) method is required to certify that the solar PV can produce the maximum amount of electricity. The major characteristics of DC-DC converters and MPPT techniques are described and evaluated in this work. Both isolated and non-isolated DC-DC converters with various converter topologies are widely and in-depth investigated. Thereafter, a comparative performance evaluation and methodical techniques to modulation schemes are used. Towards the end, a quick summary of recent advances is covered along with the design and applications of the next-generation converter. For researchers and designers working on solar PV applications, this document will serve as a valuable foundation and point of orientation for DC-DC converters.
