“…Based on previous research comparing the three schemes shown in [18,19], all have demonstrated a significant difference in THD value of the output voltage when applied to MLIs as a control technique. The carrier's disposition and its effect on the reduction of the conducted EMI will be analyzed.…”

When connecting a multilevel inverter to a load or the utility grid, two major factors must be considered: total harmonic distortion and electromagnetic disturbance due to the fast switching of the semiconductor devices. This paper focuses on these electromagnetic interference aspects of a multilevel inverter. The change in the inverter's control scheme and the change in the operating frequency on the conducted electromagnetic interference are investigated. This paper addresses carrier-based level-shifted pulse width modulation as a pulse width modulation control for the multilevel inverter. Three different level-shifted control schemes were compared at different switching frequencies to determine the effect of the control scheme and switching frequency on the electromagnetic interference. As an example of multilevel topology, a reduceddevice single-phase multilevel inverter is presented in this paper.

Due to their performances and inherent benefits, especially in medium-voltage and high-power applications, multilevel inverters have received an increasing attention in real world industrial applications. The present paper deals with a review of the main multilevel inverter topologies as well their most common derived and hybrid structures quoted in previous research works. It also encompasses an investigation on voltage harmonic elimination and THD estimation. For that reason, the paper summarizes the most relevant modulation techniques used so far to enhance the output voltage quality. Theoretical formulas evoked in the literature, for calculating the output voltage THD upper and lower bounds are reported and verified by adequate simulations.

This paper describes the customizable multi-device unified power-quality conditioner (MD-UPQC) is designed especially for multi-feeder distribution networks. The proposed MD-UPQC can exchange the power between the multi-feeders and proficiently mitigates all voltage-current associated power-quality problems, make sure to maintain balanced power-flow to consumers. At recent days, various manufacturers recommend the provision of multilevel inverters in mid-range customized compensation devices with desirable control schemes. In distinct, the 5-level diode-clamped multi-level inverter (DCMLI) is best suited for MD-UPQC over traditional 3-level voltage source inverter (VSI) topology for attaining enhanced features. In this paper, MD-UPQC has been proposed with three 5-level DCMLI modules interfaced as back-to-back with a common direct current (DC) capacitor. The simplified phase-dispositional modulation technique is easily assembled with proposed universal voltage-current reference controller for significant functioning of DCMLI-MDUPQC device. The operation and performance of proposed model and its control scheme is evaluated with MATLAB/Simulink computational tool, simulation results are presented.
