“…The proposed topology has been described in a previous publication [11], operating with the phase disposition (PD) modulation. In this paper, a centered space vector (CSV) modulation is also proposed for the asymmetrical multilevel inverter, and a comparison of the two modulation schemes is provided.…”

This paper describes a voltage-fed asymmetrical hybrid inverter based on a symmetrical hybrid multilevel DC-AC converter for high voltage/high power applications. The proposed inverter is controlled by two types of modulation patterns: low frequency (single pulse) and high frequency (sinusoidal PWM), responsible for obtaining a reduced harmonic distortion in the output voltage. Furthermore, the converter is asymmetrically powered, being fed by two sources with distinct values, obtaining seven levels phase voltage output. The results are presented with two pulse width modulation strategies, aimed at reducing the harmonic distortion in the voltage output. The operation of single-phase and three-phase circuits was verified by means of simulations and results obtained with an experimental prototype operating at a frequency switching of 1.5 kHz with a fundamental frequency of 50 Hz.

<p>Multilevel inverters have been opted for high power applications due to reduced harmonic distortion, less device voltage stress and modular structure. This work proposes new modified hybrid H-bridge multilevel inverter using auxiliary switch. This proposed inverter produces five levels output with five power devices and clamping diodes as a phase voltage and nine levels as a line voltage.The levels of the inverters are decided based on the phase voltage not on the line voltage. In this paper the performance of the proposed inverter are measured in terms of line voltage. However, by increase in the number of levels the proposed inverter with reduced number of switches produces low switching losses and improves the efficiency of the inverter. This method achieves the variation of Total Harmonic Distortion (THD) in the inverter and output voltage is observed for various modulation indices. Simulation is performed using MATLAB-SIMULINK for line to line output voltage. Variable Amplitude Phase Disposition (VAPD) strategy provides output with relatively low distortion for all the strategies. It is also seen that VAPOD is found to perform better for all strategies since it provides relatively higher fundamental RMS output voltage.</p>

“…En este sentido, es de interés optimizar la relación entre el número de niveles del convertidor y la cantidad de llaves. Existen antecedentes en los que se introducen celdas multinivel operando a distintas tensiones con esquemas de modulación híbridos [1]- [2]. A su vez las estructuras híbridas pueden explotar convenientemente las características de diferentes tipos de llaves como sus tensiones de bloqueo y frecuencias de conmutación [3]- [10].…”

This work presents a control strategy for an induction motor fed by a Cascade Asymmetric Multilevel Converter (CAMC). The approach is based on the Finite-States Model Predictive Control technique and uses the dynamic motor model and the converter model to pre-calculate the evolution of the variables of interest. These target variables are jointly compared with their reference values by means of an optimization function which allows to determine the best state among all switching combinations. This selection is carried out in a direct way, in each sampling period without modulator.
