Performance Analysis of a Modifed Three-Phase Multilevel Inverter

Inverters are crucial for various applications, including electricity systems, residential settings, the automobile industry, and manufacturing. The Multilevel Inverter (MLI) has gained popularity due to its ability to produce waveform outputs resembling sinusoidal waveforms with minimal harmonics. However, the MLI's high component count presents a significant challenge and drawback. To address this issue and make the manufacturing process more efficient and cost-effective, the paper proposes a modified topology that reduces the number of switches in the MLI architecture. The suggested modification is evaluated using simulations in the SIMULINK environment, considering parameters such as Total Harmonic Distortion (%THD), power loss, inverter cost, and size. Comparing the results of the simulations reveals several benefits of the modified topology, including a more compact design and improved cost-effectiveness.
