“…Three major multilevel inverter structures, which have been mostly applied in industrial applications, have been emphasized as the diode clamped, the flying capacitor, and the cascaded H-bridge converters with separate DC sources [3][4][5][6][7][8]. We briefly present the topologies of these three types of multilevel converters.…”

Abstract. Multilevel converters are becoming increasingly used in many industrial applications due to the many advantages that they offer. The improvements in the output signal quality, lower Total Harmonic Distortion (THD) and many other properties make multilevel converters very attractive for connecting photovoltaic generators to medium voltage grid directly or to be used in a local power supply. In this paper, we focus on the implementation of a three-phase five-level diode clamped inverter and design of a performing nonlinear controller using the Backstepping approach. The control objective is to generate, at the system output, sinusoidal three-phase voltages with amplitude and frequency fixed by the reference signal independently of load variations. The performance study of the multilevel inverter and the designed controller are made by simulations in Matlab/Simulink environment.

“…Several authors have addressed the using of multilevel inverter in large electric drive application to meet the high power demands. In [2,4,13,14] cascaded H-bridge multilevel inverter has been used by fundamental frequency switching scheme for decreasing the harmonic distortion in output voltage. Symmetrical and asymmetrical arrangements have been used in [6,15] in DTC induction motor drive by modified lookup table to improve the torque and flux profile.…”

-In this paper, analysis of cascaded H-bridge multilevel inverter in DTC-SVM (Direct Torque Control-Space Vector Modulation) based induction motor drive for FCEV (Fuel Cell Electric Vehicle) is presented. Cascaded H-bridge multilevel inverter uses multiple series units of H-bridge power cells to achieve medium-voltage operation and low harmonic distortion. In FCEV, a fuel cell stack is used as the major source of electric power moreover the battery and/or ultra-capacitor is used to assist the fuel cell. These sources are suitable for utilizing in cascaded H-bridge multilevel inverter. The drive control strategy is based on DTC-SVM technique. In this scheme, first, stator voltage vector is calculated and then realized by SVM method. Contribution of multilevel inverter to the DTC-SVM scheme is led to achieve high performance motor drive. Simulations are carried out in MatlabSimulink. Five-level and nine-level inverters are applied in 3hp FCEV induction motor drive for analysis the multilevel inverter. Each H-bridge is implemented using one fuel cell and battery. Good dynamic control and low ripple in the torque and the flux as well as distortion decrease in voltage and current profiles, demonstrate the great performance of multilevel inverter in DTC-SVM induction motor drive for vehicle application.

“…Xiao et al [6] have proposed a strategy to minimize harmonics and achieve zero error tracking. Tolbert et al [7] explored the benefits and discussed control schemes of the cascade inverter for use as an Electric Vehicle (EV) motor drive or a parallel Hybrid Electric Vehicle (HEV) drive and the diode-clamped inverter as a series HEV motor drive. Josh and Jerome [8]have stated that the power quality improvement can be achieved by reducing the harmonics at the output voltage of the inverter.…”
