| Abstract |
This paper deals with commutation problems in direct AC-AC matrix converters. It gives an overview
of existing commutation strategies and presents a new 3-STEP commutation control strategy that using both
output current and input line-to-line voltage sign allows the modulation errors, inherent in other commutation
strategies, to be eliminated. As a consequence, it is possible to extend the linear modulation region of the
converter with respect to four-step commutation strategies. Simulation results showing the effectiveness of
the new commutation strategy are given. |
