This paper analyzes two multi-carrier pulse-width modulation (PWM) techniques (N+1 and 2N+1) of the Modular Multilevel Converter (MMC) used in a back-to-back configuration under conventional dq-frame control. The PWM method applied to the MMC has an effect not only on the output waveforms and number of levels derived out of a given configuration of the MMC but also on the DC-link voltage and arm currents...
The modular multilevel converter (MMC) is based on the cascaded interconnection of half-bridge switching sub-modules and features modular characteristics that allow its expandability while providing high quality voltage and current output waveforms and removing the need for filtering. The switching frequency of each of the individual converter sub modules being maintained low and the balancing of...
