The application of amplitude coefficient in an improved multilevel matrix converter space vector modulation

The AC-AC converters (such as matrix converter) gains increasingly attention in recent years due to their merit in compact design, regeneration capability and no large energy store elements. These advantages make the matrix converter attractive in industrial applications. The multilevel topologies are advantages in high voltage, large volume, high power application with better harmonic characteristics and less dv/dt features. The multilevel matrix converter topology and its modulation method has already been discussed in previous papers and this paper concentrates on developing the concepts of amplitude coefficient for multilevel matrix converter space vector modulation (SVM) to optimize the modulation accuracy and output precision. The amplitude coefficient is discussed in detail and demonstrated by the SABER simulation results to validate the algorithm.
