Single-Phase Common-Ground-Type Buck-Boost Transformerless Photovoltaic Inverter

In this paper, a transformerless photovoltaic inverter is proposed with three main advantages. First, leakage current is eliminated by using common-ground topology. Secondly, the proposed inverter has relatively less component counts, i.e., five active switch and one diode only. Lastly, the proposed...

Summary:In this paper, a transformerless photovoltaic inverter is proposed with three main advantages. First, leakage current is eliminated by using common-ground topology. Secondly, the proposed inverter has relatively less component counts, i.e., five active switch and one diode only. Lastly, the proposed inverter provides voltage boosting feature by integrating buck-boost converter into the transformerless inverter. The performance of a 500W inverter is evaluated via PLECS simulation, It is demonstrated that the proposed inverter achieves 97.49% of CEC efficiency and THD of 1.48%.
