Multi-phase matrix converters (more than three phase) are distinctively advantageous as because of reduced per-phase current and unity power factor operation. The electrical motors supplied through these converters do have the common-mode voltage problem. In this paper, an approach to reduce the common-mode voltage is presented through appropriate vectors selection. An availability of the (35) 243...
In this paper a generalized multi-phase space vector theory is considered for developing the space vector modulation of a three-phase to seven-phase direct matrix converter (DMC). The modulation is based on the control of the voltage vectors in the first d-q plane, while imposing the remaining voltage vectors in the second and the third planes (x1–y1, x2–y2) zero. The duty cycles of the bidirectional...
