“…Barbosa et al in [80] suggested a multilevel boost current inverter for grid-connected single-phase solar PV systems. In [81,82] different inverter topologies such as MOSFET inverter topology with H6-type technique, enhanced H6 topology, HB having a capacitor divider feature, HB designed with control circuit generation, H5 with optimized technology (oH5), grid connected multilevel inverter topology, high reliable and efficient (HRE) inverter topology, hybrid zero voltage rectifier topology (HR-ZVR), grid connected multifunction inverter topology, virtual DC bus topology, buck-boost converter, buck converter, boost converter, and related topologies for solar PV grid-connected applications were addressed. Comparison of numerous transformerless single-phase inverter topologies have been presented in [76][77][78][79][80][81][82], which are applied in grid-connected PV solar systems.…”

“…In comparison with FB-derived topologies because of the higher complexity, with ratings over 10 kW (mini-central) three-phase inverters these topologies are typically used. Besides, in the range of hundreds of kW, i.e., high power (central inverter), where multilevel inverters are too significant, these topologies are also very attractive [43,[76][77][78][79][80][81][82].…”

Abstract:The research significance of various scientific aspects of photovoltaic (PV) systems has increased over the past decade. Grid-tied inverters the vital elements for the effective interface of Renewable Energy Resources (RER) and utility in the distributed generation system. Currently, Single-Phase Transformerless Grid-Connected Photovoltaic (SPTG-CPV) inverters (1-10 kW) are undergoing further developments, with new designs, and interest of the solar market. In comparison to the transformer (TR) Galvanic Isolation (GI)-based inverters, its advantageous features are lower cost, lighter weight, smaller volume, higher efficiency, and less complexity. In this paper, a review of SPTG-CPV inverters has been carried out. The basic operational principles of all SPTG-CPV inverters are presented in details for positive, negative, and zero cycles. A comprehensive analysis of each topology has been deliberated. A comparative assessment is also performed based on weaknesses, strengths, component ratings, efficiency, total harmonic distortion (THD), semiconductor device losses, and leakage current of various SPTG-CPV inverters schemes. Typical PV inverter structures and control schemes for grid connected three-phase system and single-phase systems are also discussed, described, and reviewed. Comparison of various industrial grids-connected PV inverters is also performed. Loss analysis is also performed for various topologies at 1 kW. Selection of appropriate topologies for their particular application is thoroughly presented. Then, discussion and forthcoming progress are emphasized. Lastly, the conclusions are presented. More than 100 research publications on the topic of SPTG-CPV inverter topologies, configurations, and control schematics along with the recent developments are thoroughly reviewed and classified for quick reference.

“…Therefore, strong demands to PV systems for high efficiency are always of interest. As a consequence, in order to further extend the efficiency, transformerless PV inverters have gained much popularity like in Germany and Spain, where the penetration degree of PV systems is high [4], [30]- [32]. However, galvanic safety becomes a crucial issue for transformerless systems.…”

“…One is small scale PV system and another one is large scale PV system. Small scale PV systems are mainly used in Distributed Generating systems (DG).The problem with PV DG system is for designing this system high voltage gain need to be required [1][2][3][4]. In order to achieve this high gain we are choosing Grid connected PV system that is Large scale Grid connected PV system.…”

Abstract-Due to its advantages like clean energy production and more abundance availability solar energy is the most concentrated topic from last 20 years. Grid connected PV system gaining its importance due to high demand of power across the globe. Now a days different topologies of Multilevel Inverters are developing. By using this multilevel inverters we can interface the PV systems with Grid easily and effectively. But PV system facing so many problems like power flow control and output voltage disturbances because PV systems produce irregular output voltages. This paper demonstrates the Cascade Multilevel inverter with Active and Reactive power control using Fuzzy logic control approach of for Grid Connected PV System. With the help of this model we can improve the performance of the total PV system. In this paper we proposed a 3-MW, 12-kV PV system with the Fuzzy Logic control strategy is modelled and simulated in MATLAB.
