Multisampling in interleaved converters and modular multilevel converters
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016This paper presents a method for sampling the analog variables and running the controller in multi-cell converters with a frequency higher than the switching frequency. First we introduce the multi-cell converters and highlight their similarities. Next we describe the devised method and explain the strategy to avoid simultaneous sampling and switching ...

The Multilevel Modular DC Converter
IEEE Transactions on Power Electronics, 2013The 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.

Capacitor monitoring for modular multilevel converters
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017The modular multilevel converter (MMC) is attractive for medium-or high-power applications because of the advantages of its high modularity, availability, and high power quality. Reliability is one of the most important challenges for the MMC consisting of a large number of submodules (SMs).

Synchronous Control of Modular Multilevel Converters
Proceedings of the IEEE International Symposium on Industrial Electronics ISIE-02, 2002A 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 ...
