Operating Performance of the Modular Multilevel Matrix Converter in Drive Applications

Abstract

The Modular Multilevel Matrix Converter (M3C) is an emerging topology, especially suitable for\n\t\t\t\t\t\thigh torque low speed drive applications in the medium voltage range. One special benefit is\n\t\t\t\t\t\tthe overload capability of the output currents. Up to 200% of the nominal values can be reached\n\t\t\t\t\t\tnear standstill to overcome breakaway torques without additional efforts. This contribution gives\n\t\t\t\t\t\tan experimental verification of the operating performance by using a low voltage laboratory\n\t\t\t\t\t\tprototype with 5 cells per arm. In addition, different energy balancing methods, depending on\n\t\t\t\t\tthe operating point are presented. Finally, possible applications for the M3C are discussed.
