Switching Frequency Behaviour for a Practical Matrix Converter

There are certain barriers that prevent the commercialisation of matrix converters. In the design of a real converter, the parameters that intervene in the modulation and commutation must be quantified with precision. This paper defines the commutation parameters that intervene in a vector modulation algorithm (SVM). On the other hand, it determines the commutations that occur when the double sided SVM technique is used both with semi-soft commutation, assessing the influence of the modulation frequency and technique on the design of the filter, driver consumption and their power sources. All this facilitates the dimensioning of the clock and the resolution of the variables to be used in the implementation of the algorithm in a FPGA. The paper concludes with a series of experimental results made with a Eupec module, allowing the selection of MC components
