Arm-Sensorless Sub-Module Voltage Estimation and Balancing of Modular Multilevel Converters

IEEE Transactions on Power Delivery, 2020
Modular multilevel converters (MMCs) have established their position as the choice of next-generation high voltage converters. These converters, however, require a bulk number of sensors in each phase for sub-modules (SMs) voltage balancing.

The Multilevel Modular DC Converter

IEEE Transactions on Power Electronics, 2013
The modular multilevel converter (M2C) has become an increasingly important topology in medium- and high-voltage applications. A limitation is that it relies on positive and negative half-cycles of the ac output voltage waveform to achieve charge balance on the submodule capacitors.

Synchronous Control of Modular Multilevel Converters

Proceedings of the IEEE International Symposium on Industrial Electronics ISIE-02, 2002
A novel method of direct synchronous pulsewidth modulation (PWM) is applied for control of modular multilevel converters consisting from three standard triphase inverter modules along with an 0.33 p.u. output transformer. The proposed method provides synchronisation of the voltage waveforms for each module and the composed voltage at the output of the ...
