A Simplified PWM Technique for Reduced Switch Count Multilevel Inverter
Received Sep 19, 2017 Revised Dec 30, 2017 Accepted Jan 17, 2018 Penetration of multilevel inverters (MLI) in to high power and medium voltage application has been increasing because of its advantages. A conventional two level inverter has high harmonic distortion which gives poor power quality. Lot of topologies has been developed to overcome the drawbacks of two level inverter. These topologi...
متن کاملA Space Vector PWM Scheme for Three level Inverters Based on Two-Level Space Vector PWM
Multilevel inverters are increasingly being used in high-power medium voltage applications due to their superior performance compared to two-level inverters. Among various modulation techniques for a multilevel inverter, the space vector pulse width modulation (SVPWM) is widely used. The complexity is due to the difficulty in determining the location of the reference vector, the calculation of ...
متن کاملExperimental Comparison of Carrier and Space Vector PWM Control Methods for Three-Phase NPC Converters
Multilevel converters are powerful converters in the medium-voltage high-power range. Inside this family of converters, the three-level neutral point clamped converter has its own importance. The main control methods associated with this converter are the carrier-based PWM with added DC components and the space vector PWM. Two of the most important features of the NPC converter are the neutral ...
متن کاملSpace Vector PWM Implementation for Z-Source Inverter
Space Vector Modulation (SVM) Technique has become the most popular and important PWM technique for three phase Voltage Source Inverters. Z-Source Inverters have the ability to boost the dc link voltage, thus increasing the output ac voltage beyond the values reached by conventional inverters. The enhanced ratio from ac output voltage to dc link voltage is possible due to an impedance network c...
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...
