TL;DR: The implementation of the double-sided space vector modulation, commutation, reference-frame changes, and protection of the matrix converter through a series of hardware blocks (cores) integrally implemented in an FPGA, obviating the need for sequential control and its resulting latencies and leading to an increase in the safety of the MC.
Abstract: The matrix converter (MC) presents a promising topology that needs to overcome certain barriers (complexity of the modulation and control techniques, protection systems, etc) in order to gain a foothold in the industry Traditionally, the MC has been controlled by means of a DSP, together with a field-programmable gate array (FPGA) The sole aim of the latter is to perform the safe commutation of the converter This involves a waste of resources, as the excellent features of the FPGA are infrautilized by the control system This paper deals with the implementation of the double-sided space vector modulation (DS SVM), commutation, reference-frame changes, and protection of the MC through a series of hardware blocks (cores) integrally implemented in an FPGA The designed cores are technology-independent descriptions, which means that the developed design can be used in the FPGAs of any manufacturer Moreover, the proposed design, which has been validated experimentally, has obviated the need to use a DSP Likewise, given that all the processing capabilities have been integrated in a single chip, it can be said that an FPGA-based system on a programmable chip (SoPC) has been designed Due to the computational capacity of the developed cores, processing time is reduced to the order of nanoseconds This allows a response in real time and very high modulation frequencies can be attained Moreover, these cores operate independently, and simultaneously, therefore obviating the need for sequential control and its resulting latencies and leading to an increase in the safety of the MC

TL;DR: A new method is proposed for detecting the breakage of MC semiconductors, and a new variation of SVM modulation with failure tolerance capacity is presented, which guarantees the continuous operation of the converter and the pseudo-optimum control of a PMSM.

TL;DR: In this article, the authors propose a metodeto-metodo-nomen (MMD) metodo, which is a generic metodo that can be used for a variety of tasks.
Abstract: Egun, potentzia-bihurgailuak paraleloan konektatuta aurki daitezke hainbat aplikaziotan. Konexio horiek kontrol bat behar dute, bihurgailuen arteko korronte zirkulatzaileak saihesteko eta kargaren banaketa ona bermatzeko. Proposatutako metodo guztien artean, droop metodoak nabarmentzen dira, eskaintzen dituzten malgutasuna, erredundantzia eta fi dagarritasunagatik. Lan honetan, jatorrizko droop metodoaren azterketa egingo da, eta oinarrizko printzipioak azalduko dira. Alde horretatik, jatorrizko droop metodoak dituen funtsezko abantailak eta desabantailak deskribatuko dira, baita bibliogra fi ako jatorrizko metodoa hobetzen duten aldaera batzuk ere. Azkenik, sistema baten diseinua droop metodoa erabiliz aurkeztuko da, baita simulazioetako emaitzak ere.

TL;DR: In this article, a control that resolves the traditional conflict between two of the most important properties of the single phase inverter connected to the network, i.e., current injection with low harmonic content and fast dynamics, is proposed.
Abstract: This article focuses on the design of a control that resolves the traditional conflict between two of the most important properties of the single phase inverter connected to the network, i.e., current injection with low harmonic content and fast dynamics. To do this, the use of frequency selective solutions is proposed so that these only modify the response of the system for a limited range of frequencies. The solutions employed are, furthermore, frequency adaptive. In this way, the proposed control is completely resistant to variations in grid frequencies.
