Abstract

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, it has no shoot-through risk of voltage source or capacitor and can be operated without PWM dead time. Thus the proposed inverter is greatly enhancing the safety and reliability of the system. Further, it can use power MOSFET to obtain high efficiency and allows operation with higher switching frequencies without failure risk from the poor reverse recovery of MOSFET body diode. In this paper, detailed analysis, simulation and experimental results are provided to validate the operation and advantages of the proposed inverter.
