“…In [27], a new family of single-stage buck-boost inverters has been introduced. These inverters, which are a combination of the SSI, dual-buck inverter (DBI), and high gain dc-dc converter, consist of four switches, six diodes, one capacitor, five inductors, and a boost unit, including several inductors and diodes (without active components).…”

Single-stage buck–boost inverters have attracted the attention of many researchers, due to their ability to increase/decrease the output voltage in one power conversion stage. One of the most important uses of these inverters is in photovoltaic applications, where the voltage of the solar panels varies in a wide range. In recent years, many new inverters have been proposed to improve the performance of existing structures. In this paper, the state of the art of these single-stage buck–boost inverters is discussed. The advantages and disadvantages of each structure are examined from different perspectives, such as the number of components, losses, and performance. Finally, in a general comparison, the properties of all structures are discussed and summarized in a table.

“…The presence of a direct dc‐link capacitor across the SSI will, however, require dead‐time protection for its two switches per phase‐leg. Such protection can nevertheless be avoided like in [6], where a dual‐buck inverter has been combined with the SSI. The outcome is a topology that can withstand the short shoot‐through time of a phase‐leg.…”

Split-source inverter (SSI) is a topology developed for flexibly stepping up and down its ac output voltage using only a standard inverter bridge. However, when configured as a single-phase inverter, it is still burdened by common second-order ripples. This study, therefore, proposes a modified SSI (MSSI) that can perform dual power decoupling. Unlike existing schemes, dual power decoupling makes use of both dc-and ac-side capacitors for diverting second-order ripples away from the dc source, which may be solar or other types of sources that do not work well with sizable ripples. Dual power decoupling, however, requires careful topological changes, before its effective realisation can be achieved with only a standard inverter bridge and a very small overall capacitance. Design of this capacitance and its comparison with passive decoupling have then been analysed, before testing the MSSI in experiments. Results obtained have verified the MSSI as an enhanced single-phase inverter with both buck and boost abilities while using no extra switches.

Resumo-A topologia Nine-Switch (9S) é uma interessante alternativa frente ao tradicional inversor back-to-back trifásico, pois permite a redução do número de interruptores de potência. Por outro lado, algumas aplicações dispõem de tensões CC menores que o valor mínimo requerido para síntese da tensão alternada de saída, sendo necessário o emprego de um estágio CC-CC adicional. Neste sentido, o inversor com fonte dividida ou Split-Source Inverter (SSI) agrega a elevação e inversão de tensão em um único estágio de processamento de energia, dispensando múltiplos conversores. Este artigo propõe a topologia 9S-SSI que une as características de dupla porta bidirecional trifásica conjuntamente com o estágio de elevação de tensão CC. É proposta uma estratégia de modulação PWM abordada de forma vetorial e escalar. Ambas abordagens são correlatas, contudo a primeira permite a escolha direta dos vetores de comutação enquanto que a segunda possui a vantagem da facilidade de implementação. Além disso, uma análise de perdas e o dimensionamento dos dispositivos de potência são apresentados. Resultados de simulação e experimentais são apresentados para demonstrar o bom desempenho da topologia e estratégias de modulação propostas.
