Abstract

Building Integrated Photovoltaic (BIPV) microinverter system needs lower component
counts and high efficiency at low power levels. In this context, this paper proposes a singlephase Transformerless Single-stage Buck-Boost Microinverter with sensorless control for
the Grid-integrated BIPV system. The current estimation strategy is used to control the PV
system, which reduces the costs and volume of the system. The leakage current of the system is reduced within the limits. It operates at a high level of efficiency, using an optimized
number of active and passive components. In the absence of shoot-through problems, reliability is high for the proposed topology. MATLAB/Simulink simulation with a laboratory
experimental setup for the proposed inverter for the First Solar BIPV module is designed
to validate the results. Finally, the proposed inverter was compared to different Buck-Boost
inverters at a power level of 70 W
