Novel Virtual-Ground Single-Phase Buck-Boost Inverter [PDF]
2023 11th International Conference on Power Electronics and ECCE Asia (ICPE 2023 - ECCE Asia), 2023 Due to variations in irradiance, temperature, and shading effect, the terminal voltages of photovoltaic panels are variable and therefore buck-boost inverters are required. This article presents a new buck-boost voltage-source inverter (VSI) topology. The proposed VSI is transformerless and has virtual-ground feature, which in terms mitigate the common-

Topological design and control of buck-boost multilevel inverters [PDF]
, 2019 Most dc-ac inverters developed to date can support only voltage buck energy conversion, and are therefore not suitable for use as interfacing inverters for tapping energy from renewable sources or other alternative clean sources like fuel cells, where an unrestrained voltage variation range is unavoidable.
