Carrier Based Hybrid PWM Algorithm With Reduced Common Mode Voltage For Three Phase Voltage Source Inverter Fed Vector Controlled Induction Motor Drives

This paper proposes a simple carrier based Hybrid active zero state pulse width modulation (HAZSPWM) Algorithm (HPWM) which is capable of reducing the common mode voltage produced by the Pulsewidth Modulation (PWM) Inverter fed vector controlled induction motor drive. The classical vector controlled algorithm gives variable switching frequency operation and increased harmonic distortion due to ...

Space 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...

A SVPWM to Eliminate Common-Mode Voltage for Multilevel Inverters

This paper presents a new space vector pulse width modulation (SVPWM) to eliminate common-mode voltage (CMV) for multilevel inverters. The proposed SVPWM is performed in a new coordinate system, in which the converter voltage vectors have only integer entries and the absolute coordinate increment between adjacent vectors is equal to 1. The location of the reference vector, detection of the near...

Three-level inverter configuration with common- mode voltage elimination for induction motor drive

A scheme for a three-level voltage space phasor generation with common-mode voltage elimination is proposed. An open-end-winding induction motor, fed from both ends by two threelevel inverters, which are realised by a cascading two two-level inverter, is used in this configuration. The voltage space vectors of individual three-level inverters, which generate the same commonmode voltage in the i...
