Evaluation of a multilevel cascaded-type dynamic voltage restorer employing discontinuous space vector modulation
(
IEEE Industrial Electronics Society
, 2010 , Article)
In this paper, the application of a cascaded multilevel inverter as a dynamic voltage restorer (DVR) is investigated. Two discontinuous multilevel space vector modulation (SVM) techniques are implemented for DVR control ...
A Pulsewidth Modulation Technique for High-Voltage Gain Operation of Three-Phase Z-Source Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Z-source inverter (ZSI) was recently proposed as a single-stage buck-boost dc-ac power conversion topology. It augments voltage boost capability to the typical voltage buck operation of the conventional voltage source ...
Capacitor voltage balancing using redundant states of space vector modulation for five-level diode clamped inverters
(
IEEE
, 2010 , Article)
A redundancy balancing technique for the five-level diode-clamped inverter is presented, which balances the four dc-link capacitor voltages at high modulation index and high power factor. The technique is based on dividing ...
Studying the effect of over-modulation on the output voltage of three-phase single-stage grid-connected boost inverter
(
Elsevier B.V.
, 2013 , Article)
Voltage boosting is very essential issue in renewable-energy fed applications. The classical two-stage power conversion process is typically used to interface the renewable energy sources to the grid. For better efficiency, ...
