“…Conversely, the final structure will be different as most of them require boosting. Subsequently, the power of a single PV panel is low and strongly reliant on ambient temperature and solar irradiance (ambient conditions), therefore either a buck-boost or boost converter is required to attain an adequate DC-link voltage [95][96][97][98][99]. Figure 22 presents a H-bridge boosting PV inverter with low-frequency transformer, with highfrequency transformer, and without transformer, respectively.…”

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.

Photovoltaic power generations (PVG) have been widely accepted and applied. Various power conditioning systems including boost-inverters have been also studied by many researchers. In general utilization, the actual application of such solar panels are almost installed on top of the roof of isolated house. Some residents living in the apartment house, however, have fair desires to contribute for energy saving due to natural energy generation. The generating power in such case is fairly reduced, so the system construction should balance to the reduced power. Thus, it is necessary to improve the construction toward simple one. In this paper, in order to give a reply, simple and concise power conditioner is proposed, especially integrated inverter. Considering fairly reduced generating power and narrow space of installation, the system constructions should be compact. The circuits which gratifies their characteristics are presented and examined.

“…For this reason, the proposed structure is compared with conventional step-up inverter solutions, as Z-Source Inverter (ZSI) [10], [32]- [35], Differential Boost Inverter (DBI) [5], [36], conventional two-stage Boost-Buck inverter (dc-dc Boost converter + classical VSI, named as TS-BBI) and classical Buck VSI + autotransformer (named as VSI+AT). This comparison is shown in Tables V and VI, considering a LC filter at the output, 1 Based on [10], [32]- [35].…”

“…On the other hand, step-up inverters [5]- [12] present nonlinear gain characteristic, such as Z-source [8]- [11] and SEPIC [12] inverters. These structures increase the control system complexity and make it difficult to obtain a sinusoidal waveform at the converter output.…”

-In this paper the integration between a voltage source inverter (VSI) and a switched capacitor converter (SCC) is proposed to generate a sinusoidal waveform with a double peak voltage value at the converter output terminal, without the use of a transformer or a dc-dc boost converter. The novel structure (VSI-SCC) is designed as a transformerless step-up inverter with linear gain. VSI and SCC models are individually characterized to integrate both structures in only one model. To validate the theoretical analysis a prototype was designed for a power of 1 kW, considering a dc input voltage of 200 V and an ac output voltage of 220 V (rms). In this prototype the VSI converter supplies 110 V (rms) to the SCC converter, and this converter step-up it to 220 V (rms). Furthermore, open and closed-loop control were also tested in the prototype reaching a maximum efficiency of 90%.
