Abstract

The Multi-level Inverters, or MLIs, are used extensively in applications ranging from medium to high power across many different industries. MLIs convert the voltage coming from various DC sources into stair case AC voltage across the load. The output voltage of the MLI becomes closer and closer to becoming a sinusoidal wave as the number of levels increases. This results in a number of benefits, including an enhanced harmonic spectrum of voltage and current, a lower dv/dt across the switch, less switching losses, and an increase in efficiency. Yet, the performance of the inverter is not just dependent on the number of levels in the output; rather, it is also dependent on the sort of Pulse Width Modulation (PWM) approach that is utilized. Due to greater usage of DC bus voltage, lower THD level, reduced common mode voltage, and increased practicality for digital implementation, the Space Vector (SV) based PWM technique is regarded to be the optimum option. The traditional SV algorithm, on the other hand, is more difficult to understand. Calculations in identifying sectors and subsectors, calculating switching times, and selecting the optimal Switching State Configuration (SSC) are required. These computations can be time-consuming and extensive. Researchers created a variety of SV algorithms in an effort to lessen the complexity of computation.
