Capacitor clamped multilevel matrix converter controlled with venturini method

The article is discussion with authors of [Shi Y. et al., 2005], who have presented proposal of multilevel matrix converter scheme. Because the authors have shown results of research involved only with one phase output multilevel matrix converter and suggested application one of known modulation methods to control of three phase scheme, this paper undertakes this problem. New elements of power scheme are added. Venturini modulation method is examined. Improvement of waveforms synthesized at output and reduction of reverse voltages on semiconductor elements is achieved only for the case when multilevel matrix converter operates at output frequency equal the supply voltage frequency.
