“…En este trabajo se adopto ´ el método de detección y diagnóstico de falla propuesto en (Davoodi et al, 2018), el cual consiste en evaluar los valores medios de las corrientes de fase. Para ello, se programó un filtro IIR digital pasa bajo de segundo orden, cuya expresión general se indica en la expresión (13) y en la Tabla 4 se indican los coeficientes del filtro.…”

“…En este trabajo se utiliza la estrategia de detección y diagnóstico de fallas presentado en (Davoodi et al, 2018). La estrategia consiste en evaluar los valores medios de las corrientes de fase, pudiendo demostrarse que un valor nulo indica que el convertidor funciona sin fallas, mientras que un valor positivo o negativo indica una FCAT.…”

Este trabajo propone un nuevo funcionamiento en modo tolerante a fallas aplicado a convertidores CC-CC con Puentes Duales Activos Trifasicos (CPDA3) cuando ocurre una falla de circuito abierto de transistor en el puente del lado de la carga. La propuesta consiste en modificar las senales de activación de los transistores, para lograr mantener la transferencia de potencia dentro de determinados limites despues de la reconfiguración. Este enfoque no introduce costos computacionales adicionales y no requiere la incorporacion de componentes o circuitos adicionales a la topología original. La potencia maxima que se puede transferir es mayor comparado conlas propuestas anteriores. Ademas, la ondulación de la tensión de salida se reduce significativamente, lo que permite aumentar la vida util esperada de los capacitores del filtro. Se presentan los resultados de la simulación y experimentales de un prototipo de 1.5 kW para validar el analisis teórico y la viabilidad de la propuesta.

As the power interface between the energy storage devices (ESD) and the dc link of DC Micro-grids, dc-dc converters, which have been regarded as the heart of many critical applications such as electrical vehicles, data center, and aerospace power systems, have gained more and more attentions recently. The fault diagnosis and tolerant control in dc-dc converters become essential to ensure a reliable and robust power system especially for critical applicants, where a sudden stoppage, loss of functionality, or degradation of performance might result in a catastrophe. This paper focuses on different types of faults in dc-dc converters by analyzing main failure spots and mechanism, covering catastrophic fault and parametric fault from component to system. A comprehensive review of the up-to-date fault mode analysis, fault diagnosis signals and algorithms, and fault tolerant control in various dc-dc topologies has been presented. This research will provide a useful design guideline for the reliability improvement in all forms of dc-dc converters.

“…Presently, control methods for 3-phase DAB converters primarily aim at extending the Zero Voltage Switching (ZVS) range [8][9][10] or involve strategies for detecting emergency states [11]. These control approaches leverage various modulators, ranging from fundamental Single-Phase Shift (SPS) to more sophisticated methods like those discussed in [12][13][14][15], all relying on either current or voltage-current control loops.…”

The presented work discusses issues related to the use of modern multiphase topologies of Dual Active Bridge (DAB)‐type converters. Converters of this type are widely used in most DC microgrid applications. The introduction emphasizes a comparative analysis between single‐phase and multi‐phase DAB topologies within high‐power DC microgrids, delving into their respective advantages, drawbacks, design procedures, and considerations based on the latest knowledge. The publication explores the comparison and selection of viable topologies for deployment in high‐power and high‐efficiency DC microgrids. The unified method of controlling 1‐phase and multi‐phase DAB converters was proposed in this design, simplifying the issues of DC microgrid control. All topologies were tested on the same controller concept. The study performs laboratory investigation of DAB 1‐phase and 3‐phase: Star–Star, and Star–Delta topologies. Attention was paid to maintaining uniform operating conditions of the system, contrary to studies known from the literature, all tests were carried out on the same laboratory stand and the same magnetic components in different configurations. Analytical and laboratory analyses of the Zero Voltage Switching (ZVS) region were performed, accounting for non‐linear phenomena. Based on these findings, an assessment of the system's performance in soft switching was carried out. The presented results were implemented in a simulation model and subsequently validated through tests on a constructed laboratory setup to ensure the proper operation of the system. This work meticulously presents and discusses variations in efficiency, dynamic response, phase current harmonic distribution, phase shift distribution, ZVS switching region, and more among the examined topologies. To ensure a fair comparison, the converter configuration for both simulation and laboratory models utilized identical components across all configurations.
