Space Vector Modulation Techniques for Common mode Voltage Elimination in the Three- level Voltage Source Inverter
AbstractThe low common mode voltage vector modulation technique for the three-level cascaded voltage source inverter is presented in the paper. The large number of available states for multilevel inverters can make implementation vector control strategies complicated. The main characteristic of the proposed modulation technique is its simplicity of implementation due to the fact that any availa...
متن کاملSpace Vector Modulation Based on Classification Method in Three-Phase Multi-Level Voltage Source Inverters
Pulse Width Modulation (PWM) techniques are commonly used to control the output voltage and current of DC to AC converters. Space Vector Modulation (SVM), of all PWM methods, has attracted attention because of its simplicity and desired properties in digital control of Three-Phase inverters. The main drawback of this PWM technique is 
its complex and time-consuming computations in real-time ...

متن کاملA 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...
متن کاملThree-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...
