A New Hybrid Cascaded Multilevel Inverter Fed Induction Motor Drive with Mitigation of Bearing Currents and Low Common Mode Voltage
This paper deals with new hybrid multilevel inverter fed induction motor drive. It focuses on the different topologies to mitigate the common mode voltages, bearing currents and their effects on the drive. In proposed topology, the total harmonic distortion (THD) is reduced with more number of steps in output voltage without using pulse width modulation techniques. The main advantage of this pr...
متن کاملVoltage Balancing in Diode Clamped Multilevel Inverter Using Sinusoidal PWM
Multilevel inverters offer several advantages compared to the conventional 3-phase bridge inverter in terms of lower dv/dt stresses, lower electromagnetic compatibility, smaller rating and better output features. This project presents a 9-level diode Clamped inverter using Sinusoidal pulse width Modulation techniques as the control strategies. The algorithm has been developed within the carrier...
متن کاملLink Capacitors Voltage Balancing in Diode - Clamped Multilevel Inverter
In all multilevel topology with several DC link, the voltage balancing problem of DC capacitors is a key problem. This paper proposes a new topology of chopper circuit for dc capacitor voltage balancing in diode clamped multilevel inverters (DCMLI). In the presented topology the number of switches is reduced respect to other proposed topology in literatures. Suggested topology is modular and ha...
متن کاملComparative Analysis and Simulation of Diode Clamped & Cascaded H-Bridge Multilevel Inverter using SPWM Technique
Multilevel inverters have become more popular over the years in high power medium voltage applications without the use of a transformer and with promise of less disturbance & reduced harmonic distortion. In this paper, two types of multilevel converter in three phase configuration, cascaded H-Bridge multilevel inverter (CMLI) and diode clamped multilevel inverter (DCMLI) of 5 and 7-level are mo...
متن کاملSpace Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
