Buck-Boost Single-Stage Microinverter for Building Integrated Photovoltaic Systems

Microinverters for Building Integrated Photovoltaic (BIPV) systems must have had a small number of components, be efficient, and reliable. In this context, single-phase Buck-Boost Single-stage Microinverter (BBSM) grid-connected BIPV is presented. The concept topology extracted from the buck-boost converter. leakage current in system kept under control. It uses an optimal active passive components to function at high-efficiency level. suggested provides high level reliability due absence shoot-through problems. To validate findings, simulation combination with experimental 70 W developed design approach. efficiency microinverter, total harmonic distortion grid are measured as 96.4% 4.09% respectively. Finally, comparison study has indicated advantages disadvantages inverter.
