A Single-Output-Filter Double Dual Ćuk Converter

2024 , Robles-Campos, Héctor R. , Rosas-Caro, Julio , Valderrabano-Gonzalez, Antonio , Posada, Johnny

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.

The Permanent Magnet Synchronous Motor (PMSM) drive system is extensively utilized in high-precision positioning applications that demand superior dynamic performance across various operating conditions. Given the non-linear characteristics of the PMSM, a neuroadaptive sensorless controller based on B-spline neural networks is proposed to determine the control signals necessary for achieving the desired performance. The proposed control technique considers the system’s non-linearities and can be adapted to varying operating conditions, all while maintaining a low computational cost suitable for real-time operation. The introduced neuroadaptive controller is evaluated under conditions of uncertainty, and its performance is compared to that of a conventional PI controller optimized using the Whale Optimization Algorithm (WOA). The results demonstrate the viability of the proposed approach.

Design Methodology for Interfacing DERs to Power Systems through VSC

2021 , Valderrabano-Gonzalez, Antonio , F. Beltran-Carbajal , R. Tapia-Olvera , O. Aguilar-Mejia , Rosas-caro, Julio , David Bigaud

This paper presents a methodology to connect distributed energy resources via an 84-pulse voltage source converter to three-phase system grid or load of standard or nonstandard voltage values. Transfer function blocks are included to illustrate interfacing among converters. The main input-output values to be considered in the application are detailed and the system can be modified to be included in other systems without loss of generality. The definition of the reactive component for supporting grid or load variations without degrading the overall performance is carried by for the DC-DC converter. A control variable for reducing the DC gain is used to improve the settling time. Our proposal defines the capacitive and inductive component values for an operating point and gives the option to reduce them when adding smoothed variations and adaptive controllers.

Double Dual High Step-Up Power Converter with Reduced Stored Energy

2023 , Robles-Campos, Héctor R. , Valderrabano-Gonzalez, Antonio , Rosas-caro, Julio , Hossam A. Gabbar , Bhanu Babaiahgari

This paper introduces a dual-switchhigh step-up DC-DC power converter. The proposed converter features a high step-up voltage gain, relatively low cumulative stored energy over its inductors, low voltage stress on the active switches, and high efficiency, even at a relatively high duty ratio. An assessment of the proposed converter against conventional boost and a high step-up power converter is presented in terms of steady-state time, voltage gain, stored energy over its inductors, and efficiency. The assessment shows a reduction of 81.25% and 62.5% of stored energy in inductors to comply with the same operational conditions. Simulation and experimental results are provided to validate the benefits of the proposed dual-switch high step-up power converter.
