The aim of this project is to develop a single-phase transformerless DC-AC inverter system, with a focus on reducing switching losses and mitigating the effects of leakage currents. The implementation of buck-boost transformerless inverter is used to decrease switching losses and the leakage current. The expected impact of this research is significant as it has the potential to improve the efficiency and reliability of single-phase transformerless inverter systems. The use of transformerless inverters can significantly reduce the size and cost of inverter systems, making them more accessible and attractive for a wider range of applications. Additionally, the proposed techniques for reducing switching losses and leakage currents can further improve the efficiency and performance of these systems, making them more competitive in the market. Overall, this research aims to contribute to the development of more effective and sustainable energy solutions that can benefit society by reducing the reliance on fossil fuels and mitigating the impact of climate change. The results of this project have the potential to be applied in a variety of settings, including residential, commercial, and industrial inverter systems, making it a valuable contribution to the field of renewable energy.
