Comparative of modulation techniques for modular multilevel converter

Summary:The modulation technique chosen for use in the power converter largely defines the harmonics generated, consequently it is a fundamental part that must be studied. In this paper it's shown a comparative between different modulations techniques applied to a modular multilevel converter. Sinusoidal Pulse Width Modulation, Space-Vector Modulation and Nearest Level Modulation are studied. The whole techniques are explained and finally are implemented in a hardware platform and tested in a real high-power six-level modular multilevel converter.
