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