The Modular Multilevel Matrix Converter (M3C) is an attractive topology for low-speed drives and DFIG applications. Both modularity and scalability make the topology attractive for high-power medium-voltage systems. One of the main challenges for the design and implementation of an M3C is the control platform, which has to handle a high number of submodules and measured values. This paper introduces a new control platform including a high-speed communication network between the distributed control units. The control platform and algorithms are implemented on a 15 kvar M3C test bench with 108 full bridge submodules.
