A modular multilevel converter with isolated energy-balancing modules for MV drives incorporating symmetrical six-phase machines
Diab, Mohamed S.; Williams, B. W.; Holliday, Derrick; Massoud, Ahmed M.; Ahmed, Shehab ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)A modular multilevel converter (MMC) configuration is presented as a medium-voltage high-power drive for variable-speed applications incorporating symmetrical six-phase machines. The topology employs six standard MMC ... -
Generation, performance evaluation and control design of single-phase differential-mode buck-boost current-source inverters
Darwish, Ahmed; Massoud, Ahmed; Holliday, Derrick; Ahmed, Shehab; Williams, Barry ( Institution of Engineering and Technology , 2016 , Article)Differential-mode inverter topologies are promising for renewable energy generation since they offer advantages such as passive elements sizes reduction, having decreased power losses and reduced total cost. Single phase ... -
Single-Stage Three-Phase Differential-Mode Buck-Boost Inverters with Continuous Input Current for PV Applications
Darwish, Ahmed; Massoud, Ahmed M.; Holliday, Derrick; Ahmed, Shehab; Williams, B.W. ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)Differential-mode buck-boost inverters have merits such as reduced switch number, ability to provide voltages higher or lower than the input voltage magnitude, improved efficiency, reduced cost and size, and increased power ...
