This paper presents a new transformerless inverter topology which is termed as a single-stage commonground boost inverter
(S2CGBI) for single-phase solar photovoltaic (PV) systems. The proposed topology provides a common-ground for both the dc source
and ac output to eliminate the leakage current induced by the parasitic capacitance of PV cells. Voltage-boosting is made possible
with the incorporation of only one inductor, which renders the realization of single-stage power conversion. The proposed pulse
width modulation (PWM) technique is capable of charging the inductor with a constant duty-cycle while guaranteeing ac output
generation. The operation of the proposed S2CGBI is analyzed. Simulation and experimental results are provided to validate the
effectiveness of the proposed topology and modulation scheme.
