  • Abstract

    The Modular Multilevel Matrix Converter (M3C) performs a direct three-phase AC to AC power
    conversion and is highly suitable for medium voltage high power drive applications. One area of
    application are high speed drives such as compressors. However, additional balancing power
    components which reduce the output power capability of the M3C when input and output frequencies
    are similar occur. This paper analytically examines the operation behavior and power
    capability in these operation points in order to assess whether the M3C can generate these
    additional components without oversizing the converter’s components. Subsequently, the theoretical
    evaluation is verified by a laboratory scaled prototype with a rated power of 15 kW.
