Investigation of the effect of the gap at the zero-crossing point of PWMs creating the first level voltage in a multi-level inverterCan, ErolSayan, Hasan HüseyinDifferent First-LevelPWM OperatingZero-Point GrossingThe usage of multi-level inverters in converting direct current to alternating current is one of the most demanded and used methods. While creating multi-level voltage with inverters, the operating times of the switches that constitute the first step of the alternating voltage determine the gap of the step at the zero-crossing point. This situation can be preferred to create an extra level. Therefore, this article examines the effect of variation in operating times and frequencies of first-step PWMs on this zero-crossing point. First, the inverter structure providing load voltage is given in the study. Then, the transition of PWM run times is tried for different first-level voltages on the loads. The results obtained show the operation times of PWM at the transition point are quite effective on the load currents and voltages. © 2023 Kuwait University.Elsevier B.V.2023Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/12063https://doi.org/10.36909/jer.159412307-1877enJournal of Engineering Research (Kuwait)info:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12063
