Item type:Publication, A Method for Stabilizing Dual Active Bridge Converters with Constant Power Loads(Institute of Electrical and Electronics Engineers (IEEE), 2025); Md Habib UllahDual Active Bridge (DAB)-based energy storage systems are the key to integrating renewable energy sources into the power grid. However, DAB converters can become unstable due to the negative impedance characteristic of constant power loads (CPLs), posing a risk to the overall system stability. To address this issue, a stabilization method based on inductor saturation is proposed. This method ensures converter stability by expanding its stability region, mitigating the risk of destabilization from fastacting transients. Based on the mathematical analysis that uses full-order continuous-time average models and the characteristics of a CPL, the proposed method effectively stabilizes the DAB converter by expanding the stability region and achieves a fast dynamic response, even under large signal variations. Unlike other advanced stabilization methods, this approach does not require any modification of the main control objectives, such as bandwidth, voltage regulation, or load performance. The experimental results support the theoretical analysis, demonstrating the effectiveness of the proposed converter and showing an improvement in the overall efficiency of the converter under high load conditions. © 1972-2012 IEEE.17 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A comparative evaluation of modulation strategies for Hexverter–based Modular Multilevel ConvertersIn this work two different modulation strategies termed: i) nearest level control, and ii) phase disposition-sinusoidal pulse width modulation, are described, simulated and compared when applied to a Hexverter-based modular multilevel converter. In addition, two different voltage balancing algorithms are implemented and evaluated. Furthermore, total harmonic distortion regarding three-phase system voltages are assessed. In the end, synthesized branch voltage spectrum for each modulation strategy is analyzed.26 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Improved interleaved Ćuk power converter(2023); ; ; Posada, JohnnyAn improved interleaved Ćuk power converter called in short –"Interleaved Two"– is designed and presented in this article. It is investigated and compared to a similar interleaved Ćuk power converter named as –"Interleaved One"– . The result is that the "Interleave Two" topology requires less reactive elements than the "Interleaved One" to achieve same performance, it will offer the possibility to reduce its size and economic cost. The operational principle and modeling is presented thoroughly. Moreover, simulation results comparing steady state time, output voltage, input current ripple and efficiency are presented. Additionally, in order to validate the performance of the "Interleaved Two" converter experimental results are included.2 16Scopus© Citations 1 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Numerical Optimization of Switching Ripples in the Double Dual Boost Converter through the Evolutionary Algorithm L-SHADE(2020); ; <jats:p>Power-electronics based converters are essential circuits in renewable energy applications such as electricity generated with photovoltaic panels. The research on the field is getting increasing attention due to climate change problems and their possible attenuation with the use of renewable energy. Mathematical models of the converters are being used to optimize several aspects of their operation. This article is dedicated to optimizing (through the mathematical model and an evolutionary algorithm) the operation of a state-of-the-art converter. The converter, which is composed of two parts or phases, is controlled by pulse width modulation with two switching signals (one for each phase). The converter provides by itself low switching ripple in both the output voltage and the input current, which is beneficial for renewable energy applications. In the traditional operation, one of the switching signals has an algebraic dependence on the other one. This article proposes a new way to select the duty cycle for both signals. In the proposed method, duty cycles of both phases are considered independent of each other; this provides an extra degree of freedom; on the other hand, this produce that the possible combinations of duty cycles which produce a certain voltage gain is infinite, it becomes a problem with infinite possible solutions. The proposed method utilizes the a linear success-history based adaptive differential evolution with linear population reduction, also called L-SHADE algorithm for simplicity, to find the two duty cycles that achieve the desired voltage gain and to minimize the converters switching ripple. The obtained results are compared with the former operation of the converter; the proposed operation achieves a lower output voltage ripple while achieving the desired operation (voltage gain).</jats:p>Scopus© Citations 5 1 11 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A Single-Output-Filter Double Dual Ćuk Converter(2024); ; ; Posada, Johnny<jats:p>This study introduces an innovative version of a recently studied converter. A Double Dual Ćuk Converter was recently studied with advantages like the possibility of designing it for achieving a low-input current ripple. The proposed converter, called the Improved Double Dual Ćuk Converter, maintains the advantages of the former one, and it is characterized by requiring one less capacitor and inductor than its predecessor. This allows addressing the challenge of optimizing the topology to reduce component count without compromising the operation; this work proposes an efficient design methodology based on theoretical analysis and experimental validation. Results demonstrate that the improved topology not only retains the advantages of the previous version, including high efficiency and robustness, but also enhances power density by reducing the number of components. These advancements open new possibilities for applications requiring compact and efficient power converters, such as renewable energy systems, electric vehicles, and portable power supply systems. This work underscores the importance of continuous innovation in power converter design and lays the groundwork for future research aimed at optimizing converter topologies. A detailed discussion of the operating principles and modeling of the converter is provided. Furthermore, simulation outcomes highlighting differences in steady-state duration, output voltage, input current ripple, and operational efficiency are shared. The results from an experimental test bench are also presented to corroborate the efficacy of the improved converter.</jats:p>Scopus© Citations 1 13 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Modeling, Modulation and Control of Hexverter-Based Modular Multilevel ConvertersElectrical power extraction from renewable energy sources such as photovoltaics (PV), wind farms, and some others, have their own technical challenges. It is necessary to perform the power processing tasks according to the nature of the power supply and, at the same time, it is required to be compliant with technical regulations and particular needs of final users. These tasks are achieved with the development of power electronics converters and suitable control systems. Modular multilevel converters (MMCs) have been during the last years, and will continue to be in the near future, a trending research topic. To better process the electrical power, MMCs can be used where two or three level power converters are used today. This is essentially due to multiple advantages, such as, (i) inherent fault tolerance or some times called redundancy, (ii) application in medium and high power levels, (iii) high scalability: in function of the number of power modules, (iv) better quality of output power, and (v) comparatively low switching frequency.17 1 - Some of the metrics are blocked by yourconsent settings
