N2 - Matrix converter based open-end winding drives modulated with rotating vectors eliminate the high-frequency common-mode output voltage that could otherwise cause motor failure. Unlike back-to-back converters, no intermediate dc bus capacitor is required - better power density and reliability may, therefore, be achievable. A high voltage transfer ratio and input power factor control capability put these open-end winding drives at a significant advantage over conventional matrix converters. At least three realizations of the matrix converter based open-end drive are possible. This paper compares these three realizations to identify the best topology and presents experimental results validating its capabilities. Filter optimization, loss-optimal vector sequences, and other practical considerations are also discussed. Finally, a comparison with the state-of-the-art back-to-back converters is provided to investigate if the potential improvements are in fact attainable.
