“…A pesar del incremento de coste que estos problemas suponen, suelen ser una buena solución para accionamientos de gran potencia o cuando se dispone de varias fuentes de tensión continua como en las aplicaciones de automoción. En (Walczyna and Hill, 1993;Zhang et al, 2012;Dharmaprakash and Henry, 2014) se propone un control con un inversor de tres niveles y en (Escalante et al, 2002) se propone una aplicación de control DTC con un invesor de cinco niveles. Dado que el número de vectores disponible ha aumentado, en este segundo caso se definen doce sectores (en lugar de los seis del DTC convencional) y cuatro tablas de disparosóptimos para cuatro rangos de velocidades diferentes.…”

“…They are popular in comparison to other motors, such as DC motors, because of their low cost, reliability, and flexibility [2,3]. Induction motors utilize more than twothirds of all industrial electrical energy [4]. Important advances in materials, power electronics, and high-performance microcontrollers are being made all the time, even though the basics of IM functioning have been known since the turn of the century.…”

Induction motors (IM) that are driven using the conventional direct torque control algorithm (DTC) suffer from vital drawbacks which are high ripples in the torque and flux. These ripples result due to the use of a look-up table and hysteresis comparators which causes variable switching frequency. Moreover, the use of a traditional two-level inverter leads to the production of low-quality voltage and current. The work presented in this paper proposed a modified control system to overcome these drawbacks. The proposed control system is based on the use of the space vector modulation-based DTC algorithm (DTC-SVM) for driving three-phase IM via a three-level T-Type inverter. The conventional DTC-SVM algorithm has been modified to match the work of the proposed inverter. The modification process was based on the mapping of the standard DTC-SVM algorithm in the space vector of the three-level inverter. The conventional and the modified control systems are implemented using MATLAB/Simulink package. The comparison of the standard and the modified DTC-SVM has been performed by simulation. Simulation results showed the superiority of the proposed algorithm in terms of reducing ripple in torque and flux and improving the quality of current and voltage supplied to the motor.

“…Reduction of THD% is achieved by improved switching sequence for 3-level diode clamped converter of multilevel space vector PWM technique [13]. Simulation results of multi-level diode clamped converter with direct torque control (DTC) of 3-phase induction motor (IM) are compared with 2-level converter under various speed condition with different loads [14]. Optimized switching sequence of multilevel neutral point diode clamped converter compared with conventional space vector PWM fed 3-phase induction motor, by means of that percent of THD reduced significantly with improved switching sequence of SVPWM [15].…”

Recent power distribution networks comprise abundant sensitive loads, which extremely impact the power quality of source in electrical power networks. Voltage dip, voltage rise, imbalanced voltage, line notching and distortion of harmonics are problems of power quality frequently take place. Pre-disturbance voltage compensation strategy and phase-locked-loop (PLL) based dq- space vector control are presented to improve a Dynamic Voltage Restorer (DVR), which restore the magnitude of voltage disturbance and displacement of phase angle to prior of voltage disturbance. 3-phase Multilevel strategy of Space Vector Pulse Width Modulation (MSVPWM) based- Multilevel Diode Clamped Converter (MDCC) is proposed as switching pulse signals employed low frequency, which creates high levels of voltage and fewer harmonics in the output waveform in comparison to 2-level SVPWM based- DVR. 3-level SVPWM based- DVR under balanced and imbalanced distortion voltage disturbances included sags and swells injected appreciated quantities of voltage, thereby attained ideal sinusoidal waveform with lower Total Harmonic Distortion THD% compared to 2-level SVPWM based- DVR. Furthermore, real and imaginary powers balanced effectively at sensitive load during various distortion voltage disturbance conditions via presented work. The proposed simulation model of multi-level SVPWM based- DVR is implemented by dedicating the software system of MATLAB/SIMULINK. The results of simulation exhibit the effectiveness and efficiency of the presented work under different distortion voltage disturbance conditions.
