For single phase grid-connected solar PV
applications, the single-stage buck-boost transformer less
inverter (BBTI) topology is the basic foundation of this study. In
this design, leakage currents are eliminated because the input
PV source shares a common ground with the grid's neutral.
Also, the suggested design includes a buck-boost converter that
maintains the maximum power point despite a wide range of
input PV voltage. One less energy storage inductor is used in the
suggested design, allowing for symmetric grid functioning
during both half cycles. Moreover, the suggested topology's two
out of five switches that operate at line frequency incur low
conductivity losses, while the remaining switch operates at high
frequency incurs low conductivity losses. To manage the
suggested inverter topology, a straightforward sine-triangle pulse
width modulation approach is suggested. All operational modes
are examined, and a thorough explanation is provided. The
suggested approach provides more efficiency while reducing
output current THD
