(
Elsevier Ltd
, 2014 , Article)
Semiconductor advancements in the past three decades have positioned the voltage source converter-based HVDC (VSC-HVDC) solution as a practical and popular alternative to its line-commutated converter high voltage DC ...
A static three-phase to five-phase transformer based on Scott connection
(
Elsevier B.V.
, 2014 , Article)
Multiphase machines have become challenging candidates for safety-critical applications that require wide fault tolerant capabilities and higher system reliability. However, this adds more complexity to the adopted power ...
Investigation of sensorless capacitor voltage balancing technique for modular multilevel converters
(
IEEE
, 2014 , Conference Paper)
Modular Multilevel converters (MMC) have become one of the most promising topologies for DC-AC conversion in recent years. Capacitor voltage balancing is a vital issue for proper operation of the MMC. Generally, conventional ...
An interline dynamic voltage restoring and displacement factor controlling device (IVDFC)
(
IEEE
, 2014 , Article)
An interline dynamic voltage restorer (IDVR) is invariably employed in distribution systems to mitigate voltage sag/swell problems. An IDVR merely consists of several dynamic voltage restorers (DVRs) sharing a common dc ...
A dual three-phase induction machine based flywheel storage system driven by modular multilevel converters for fault ride through in HVDC systems
(
IEEE Computer Society
, 2016 , Conference Paper)
One of the main challenges of voltage source converter based high voltage direct current (VSC-HVDC) transmission systems is the AC faults at the grid side. This work introduces the integration of multiphase induction machine ...
Fault-tolerant control of five-phase current source inverter for medium-voltage drives
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Multiphase Machines offer a promising solution to many practical challenges due to their advantages over the three phase counterparts, as fault-tolerant capability and lower torque ripple magnitude. Among different multiphase ...
