“…El espacio que este tipo de estructura utiliza es menor en comparación a los convertidores que se encuentran en el mercado [10]. Es gracias a lo anterior que el convertidor matricial posee una densidad de potencia mayor que los otros convertidores, la cual llega a ser 5 veces mayor que otras topologías de convertidores [11], pero así como posee una densidad de potencia mayor la cantidad de semiconductores que necesita para operar también es mayor [9]. Esta característica lo hace ser una opción muy aplicada en elárea aeroespacial.…”

Power converters play a fundamental role in grid interconnection systems. In this article we present the design, assembly and start-up of a multimodular converter. The different stages and design components of the system are detailed. The main idea of this paper is to provide the reader with a guide on how to proceed with the design and assembly of this type of converters.Index Terms-convertidores matriciales, convertidores de potencia, interconexión de redes.

“…On the other hand, space‐vector‐based methods intrinsically incorporate this feature. Thus, methods discussed by Venturini in [15, 16], by Roy in [17], carrier‐based methods [18] etc., fall under the scalar category. Space‐vector‐based method, on the other hand, is applied in two ways: direct [19] and indirect [20] approaches.…”

This paper addresses multiphase matrix converter (MPMCs) modulated with Venturini's classical scalar approach. The solution to obtain time-varying modulation functions was limited to 3 × 3 configuration, which was later extended to 3 × n configuration. The equations had four constants that were common to all modulation functions; out of which two were defined arbitrarily and other two were found analytically by reducing the equation to a two-variable optimisation problem. However, in this work, an attempt is made to provide flexibility in finding other solutions by taking all the constants as variables. Thus, Differential Evolution (DE) algorithm is adopted in the proposed modulation approach to solve the complex equations thus obtained. Another aim is to find the solution for the MPMC, where inputs are more than three. It is found that the optimal solutions exist only for 3 × n configuration and are in close approximation with the results of analytical approach. Other solutions were found for certain input and output frequencies and voltage transfer ratios whose results are discussed. It is also found that the solution does not exist for configurations with input phases are other than three. The discussion is supported by simulation and experimental results on a 3 × 7 matrix converter at various values of voltage transfer ratios and input/output frequencies.

“…The authors introduced the name 'matrix converter' and proposed control theory known as Venturini modulation [14]. Different control techniques known as modified Venturini modulation, scalar control strategy, space vector modulation and carrier based modulation technique were proposed [15][16][17][18][19][20][21]. Zuckerberger introduced the single phase matrix converter for direct AC-AC conversion [22].…”

In this paper, a real time implementation of selective harmonic elimination pulse width modulation (SHEPWM) using Real Coded Genetic Algorithm (RGA), Particle Swarm Optimization technique (PSO) and a new technique known as Linearization Method (LM) for Single Phase Matrix Converter (SPMC) is designed and discussed. In the proposed technique, the switching frequency is fixed and the optimum switching angles are obtained using simple mathematical calculations. A MATLAB simulation was carried out, and FFT analysis of the simulated output voltage waveform confirms the effectiveness of the proposed method. An experimental setup was also developed, and the switching angles and firing pulses are generated using Field Programmable Gate Array (FPGA) processor. The proposed method proves that it is much applicable in the industrial applications by virtue of its suitability in real time applications.
