Abstract :
In this paper an analytical approach to predict the current ripple in an inductive load fed by a matrix converter controlled with space vector modulation is presented. The analysis aims at determining the optimal modulation strategy that minimizes the rms value of the load current ripple. The minimization procedure is based on the analysis of the locus described by the current ripple in the d-q reference frame. As a result, a set of equations which allows the on-line calculation of the optimal SVM switching pattern is found. It has been verified that it is possible to obtain a current ripple lower than that of traditional SVM strategies, and with a reduced number of commutations. Experimental results are provided to confirm the theoretical approach
