"A Novel Transformerless Single-Phase Three-Level Buck-Boost Inverter", 2023 IEEE Applied Power Electronics Conference And Exposition, APEC, Proceedings, pp. 114-120, 2023.1048-2334http://hdl.handle.net/20.500.12416/7024This paper proposes a novel transformerless, single-phase, three-level, buck-boost inverter. The proposed inverter can suppress the leakage current drawn from the input power source and provide a long-lasting solution for applications with a wide range and unregulated input voltage. Unlike similar topologies, in the proposed inverter there is no need to have a mid-point of DC sources or DC bus capacitors at the input side of the inverter. A single-phase, three-level, buck-boost inverter for realizing the power stage with 110-Vrms output AC voltage and a range of 100V-200V input DC voltage is investigated in this study. The proposed topology has been proven through theory, computer simulations, and experimental studies with SiC MOSFETs-based prototype of a 300-VA power supply. Theory, computer simulation, and experimental results are all correlated.eninfo:eu-repo/semantics/closedAccessAalborg InverterAnkara InverterBuck-BoostInverterSingle-PhaseThree-LevelTransformerlessH5 InverterConference Object11412010.1109/APEC43580.2023.10131374
