Cell capacitor sizing in multilevel converters: cases of the modular multilevel converter and alternate arm converter [PDF]
IET Power Electronics, 2015 Multilevel converters, such as the modular multilevel converter (MMC) or the alternate arm converter (AAC), rely on charged capacitors in their cells to generate their AC voltage waveform. Since the cell capacitors are physically large and occupy approximately half the cell volume, their capacitance must be kept minimal while limiting the voltage ...
