Implementation of Five Level Multilevel Inverter with Reduced Leakage Current

As nonrenewable fuels deplete; most of the businesses are transitioning to renewable energy. Solar energy is a abundant in nature and is a reliable source of renewable energy. In today's photovoltaic systems, multiple inverters are employed to convert DC power to AC power. Because of the low harmonics and low leakage current levels, multilevel inverters are more efficient than full-bridge inverters. In the presented work, various types of grid-connected multi-level inverters are simulated and results are compared. According to the simulation output, the value of leakage current is lowest in the case of a 5-level transformer less multilevel grid-tied inverter.
