Improved control strategy of the Modular Multilevel Converter for high power drive applications in low frequency operation
(2016)
Modular Multilevel Converters (M2C) are considered an attractive solution for high power drives. However,
its operation at low rotational speeds can produce undesired voltage fluctuations in the M2C capacitors.
In this ...
