Design and Performance Analysis of New Seventeen Level Reduced Switch Count Multilevel Inverter

Multilevel inverter has emerged newly as a very important alternate in the area of high-power medium-voltage energy control.The main problem in this technology is high devices, total standing voltage, cost, THD and efficiency.This paper's main goal is to provide a 17-level multilevel inverter with only 8 switches and 4 diodes.Four different unequal DC sources are used in this arrangement to produce the output voltage waveform with 17 levels.For the proposed inverter, the cost function per level, efficiency, total standing voltage, conduction losses, and switching losses have all been calculated in detail.Typical inverters have higher switching losses, prices, and harmonic distortion because they have more semiconductor power switches, diodes, capacitors, driver circuits, and DC sources.The switching components of the suggested arrangement have been controlled using the nearest-level control approach.The suggested multilevel inverter offers a higher efficiency of 98.24%, cost function of 5.7 for a weight coefficient of 1, improved power quality, and higher reliability.The total harmonic distortion produced by this inverter is 3.43%, which comes under the IEEE standard of 5%.
