A review on single-phase boost inverter technology for low power grid integrated solar PV applications

Solar Photovoltaic (SPV) inverters have made significant advancements across multiple domains, including the booming area of research in single-stage boosting inverter (SSBI) PV scheme. This article comprehensively covers four critical components of the system, namely boosting topologies, voltage and current control methods, Maximum Power Point Tracking (MPPT) methods, and grid synchronization. It conducts thorough analysis and comparisons of various topologies in terms of their performance, cost, volume, lifetime, and grid interfacing requirements for a 200 W reference power level. Furthermore, it investigates the advantages and disadvantages of single-phase inverter control methods and synchronization methods. The MPPT techniques are evaluated based on complexity, robustness, and precision. This paper presents an outline of the series-connected Low Voltage AC (LVAC) scheme, along with several potential areas for further study. By providing insightful analysis and development ideas, this article equips researchers to design and develop optimized single-stage PV systems with increased efficiency and effectiveness.
