| Abstract |
This paper deals with the problem of current commutation in matrix converters. Existing strategies are reviewed. An improved implementation of a semi-soft snubberless commutation method is presented. This method employs current detection within intelligent gate drive circuits for each bi-directional cell. Each cell communicates with the other cells to provide accurate current direction information. The problems with other methods at low currents are overcome. Experimental results verifying the method are presented. |
