Four-switch buck-boost inverter for stand-alone and grid
This paper proposes a novel highly reliable single-stage buck-boost inverter. It can be operated as grid-connected and stand-alone inverter. In a single-stage, it can generate an output ac voltage higher and lower than the input dc voltage. The proposed inverter can be employed in grid-connected single-phase PV systems without injecting large dc current into the grid. In addition,
