Control strategy for modular multilevel matrix converters at high output frequencies
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 $_{out}$ $ \geq \ $ $_{in}$ the energy pulsation in the converter cells are dominated by the second harmonic of the input frequency. These energy pulsations can be identified and
