One important reason is its high control complexity. It is therefore relevant to propose a simpler but efficient modulation scheme, similar as three phase VSI modulators with the well-known symmetrical carrier-based ones. The modulation presented in this paper is equivalent to a particular Space Vector Modulation (SVM) and takes into account harmonics and unbalanced input voltages, with the same maximum voltage transfer ratio (86%). The aim of this work is to propose a simple and general pulse-width-modulation method using carrier-based modulator for an easier matrix converter control. Furthermore, a simple duty cycle calculation method is used, based on a virtual matrix converter. Finally, simulations and experimentations are presented to validate this simple, original and efficient modulation concept equivalent to matrix converter SVM.

A review of predictive control techniques for matrix converter applications

“…for Matrix Converters Scalar Techniques [5], [6] Pulse Width Modulation [7]- [10] Direct Torque Control [11], [12] Direct Power Control [13], [14] Model Predictive Control [15]- [38] Other Methods Direct Transfer Function [5] Scalar (Roy) [6] Carrier Based PWM [7], [8] Space Vector Modulation [9], [10] Predictive Current Control [15]- [24] Predictive Torque Control [25]- [29] Predictive Power Control [30]- [33] Predictive Voltage Control [34]- [36] Unity Transfer [37], [38] [40], [41] Fig. 2.…”

“…As reviewed in [39] and shown in Fig. 2, the most commonly used techniques are Venturini [5], carrier-based pulse width modulation (PWM) [7], [8], space vector modulation (SVM) [9], [10] and direct torque control (DTC) [11], [12]. Other control methods that have been applied to MCs in specific applications are fuzzy control, neural networks and genetic algorithms [40], [41].…”

An Efficient Second-Order Approach to Factorize Sparse Matrices in Recommender Systems

“…Note that H f (X) is of size n×n. Therefore, the computational complexity of (2) is Θ(n 3 ) where n denotes the number of desired parameters [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. In context of LF-based CF described by (1), we have n = (|U|+|I|)d. Thus, with huge user and item counts which are commonly seen in real applications, it is intractable to employ (2) directly.…”

Space vector PWM for a three-phase to six-phase direct AC/AC converter

“…It is to be noted here that the most common configuration of the matrix converter discussed in the literature is three-phase to threephase [2]. Recently, topologies of matrix converter with threephase input and multi-phase outputs have been reported [4][5][6][7][8][9][10][11][12][13][14][15][16]. This paper is motivated from the recent development in three-phase input and multi-phase output matrix converter.…”
