Control strategy for modular multilevel matrix converters at high output frequencies
2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017 This paper presents a new control strategy for Modular Multilevel Matrix converters where the output frequency is higher then the input frequency. In operating points when ω$_{out}$ $ \geq \ $ ω$_{in}$ the energy pulsation in the converter cells are dominated by the second harmonic of the input frequency.
