SUMMARY:

This work presents a new transformerless photovoltaic inverter topology with the objective of reducing the leakage current to levels established by international standards and ensuring high efficiency compared to other existing topologies in the literature. The work includes a detailed description of the proposed inverter operating principle, the modeling and analysis of the system frequency response, as well as simulations to compare the performance of the proposed converter with other topologies in terms of leakage current levels, Total Harmonic Distortion (THD) of the injected current and conduction and switching losses of semiconductor devices. The results show that the proposed inverter presents excellent performance in mitigating the leakage current in photovoltaic systems, together with a reduction in switching and switching losses in relation to conventional topologies.
