A Novel Single-Stage Buck–Boost Inverter
IEEE Transactions on Power Electronics, 2022 Traditional nonisolated multilevel inverters based on the buck–boost principle usually have some disadvantage such as necessary dead time or capacitor precharging. To overcome these, a new transformerless single-stage buck–boost voltage source inverter topology and its control method are proposed.

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-
