“…Many different configurations of the VSI-based converters have been reported (also known as a dual active bridge) [55,56,77,[125][126][127][128][129][130][131][132][133][134][135][136]. In [105], the topology consists of two voltage source full-bridges, as shown in Figure 18.…”

This paper presents a review of isolated matrix inverters. The study contributes to creating a point of reference for a comprehensive classification of existing solutions. Over 30 topologies were reviewed, and the main advantages and disadvantages discussed. Applications of isolated matrix inverters are summarized in a tabular form to demonstrate their flexibility for different power and voltage levels achieved due to the presence of a transformer. These inverters have been proposed for the uninterruptible power supplies, high and low-voltage/power photovoltaic systems, low-power fuel cell, different low- and high-voltage battery and/or electric vehicle chargers, audio amplifiers. The fully controlled switches on both terminals of these converters typically can provide the bidirectional power transfer capability, which is also addressed for most of the topologies, but requires some modification in their modulation strategy. Average efficiency of today’s isolated matrix inverters is comparable with the two-stage power converters; however, they can provide higher reliability and lower cost.

“…En el caso de [21] el documento presenta un convertidor bidireccional aislado de DC a AC trifásico, el aislamiento lo realiza en base a un transformador trifásico que trabaja en alta frecuencia, en esta propuesta no se utiliza la estrategia de control predictivo, a cambio de esto se propone una estrategia de control que busca controlar el flujo de potencia en ambas direcciones, el circuito presentado utiliza veinte IGBTs y se reportan resultados buenos en la calidad de la energía eléctrica y el control del factor de potencia, además de tener conmutaciones suaves, el convertidor que se describe está orientado para aplicaciones que integren fuentes renovables a la red principal de energía eléctrica.…”

The development of a three-phase electronic power converter is presented, the converter uses IGBTs as electronic power devices, it can act bi-functionally as a threephase full-wave rectifier or as a three-phase three-arm inverter, using the same three-phase power bridge For the conversion, the control design is carried out using the FCS-MPC technique (Finite Commutations Set-Model Predictive Control). The quality of the electrical energy conversion is evaluated, evaluating the average and effective parameters of the voltages and currents, with various types of loads. As well as distortion with the THD coefficient, frequency and phase. The converter seeks to be very flexible and somewhat universal for the conversion of AC-DC and DC-AC energy, for diverse applications in the field of distributed power generation systems, particularly with the presence of renewable energy sources. Modeling and testing have been done with MATLAB, SIMULINK. The loads have also been modeled for typical applications with real characteristics, so in the case of rectifier the test load has been considered a lithium ion battery, then with a 5HP, 240 v and 1750 rpm DC motor, to later test with a general load of RL characteristics. For the inverter, it is tested with a balanced three-phase RL load and then with a three-phase squirrel cage-type asynchronous motor. The results are presented by means of graphs and tables for a better understanding of said results obtained in the simulations. The functionality and operation of the developed converter is explained by means of block diagrams that incorporate the units that make up the converter including the control units, the command unit, the operation selection switch unit, as well as the power unit. The results obtained show good functional characteristics of the converter in its two modes of operation, reflected in the parameters measured in the simulation tests.

“…Two positive effects are clearly visible in Table 1. First, by increasing the number of CSCs, i.e., the number of levels, the total equivalent AC inductor value (with interleaving control) is significantly reduced by a factor equals to (number of CSC) 2 . For example, for 20 CSCs, the total AC inductor falls from 10 mH to 25 µH.…”

“…Isolated DC-AC step up bidirectional converters are presently of great interest for connecting storage batteries to the grid for many applications, such as electric mobility and remote applications, as well as renewable energy storage [1][2][3]. These applications generally require an inverter/rectifier stage, as well as a DC-DC step-down/up stage to adapt the voltage rating of the battery.…”

DC-AC Isolated Power Converter Array. Focus on Differential Mode Conducted EMI

et al. 2019

This paper introduces the implementation of a DC–AC step up isolated converter from associations of bidirectional Conversion Standard Cells (CSCs). The designed multi-cell converter is an array of standardized converter cells. It is described and then compared to a reference converter with respect to differential mode conducted electro-magnetic interference (EMI). The paper outlines the motivation for developing a generic multi-cell approach before underlining the benefits from the point of view of conducted EMI when implementing power converter arrays (PCAs). In particular, it is shown that in PCAs, the differential mode (DM) EMI filter can advantageously utilize distributed CSCs, making it possible to use very low value AC inductors to filter the AC current ripple. Experimental results are provided to validate the analysis carried out in the paper.
