Present-day electric vehicles employ conventional two-level inverters. However, the usage of multi-level inverters as the propulsion inverter in electric vehicles has gained popularity in recent years. Thus, this thesis examines the performance of several topologies of multi-level inverters as traction inverters, and a comparison with conventional two-level inverters is made. Multiple output voltage levels can be achieved with a multi-level inverter, which contributes to a decrease in THD and losses. The majority of this work's implementation and analysis is done using the PLECS software, which models and simulates several multi-level inverter topologies and compares them in a number of ways, including losses, THD, Investigations are being conducted on a two-level and a three-level multi-level inverter. Four distinct topologies (i.e., T-type neutral point clamped inverter, Flying capacitor inverter, Neutral point clamped inverter, and Cascaded H-bridge inverter) through simulation, analysis, and modeling. For the inverter models, two distinct switching strategies—Sine wave PWM and Space vector PWM—are used. However, phase-shifted sine wave PWM is employed for the multi-level inverter versions. The inverter's size, cost, and modulation technique complexity all rise with the number of levels. Thus, choosing an inverter involves balancing all of the aforementioned factors.
