Recently our colleagues Mohamed Debbat, Camilo Henao, Antonio Pepiciello and Jose Luis Domínguez García from IREC – Institut de Recerca en Energia de Catalunya published their latest paper on “Sliding-Mode Based Control Technique for Triple Active Bridge DC-DC Converter” within the project at XV International Symposium on Industrial Electronics and Applications – INDEL 2024 in Banja Luka (Bosnia and Herzegovina) held at Faculty of Electrical Engineering, University of Banja Luka.
Our colleague, Mohamed Debbat presented this work on the capability of interfacing various energy sources, storage units and loads, multiport converters (MPCs) are increasingly being considered in distribution system applications. As a MPC, Triple Active bridge (TAB) is one of the most relevant.
It is a high order nonlinear and magnetically coupled system. Design a controller, for this converter, capable to ensure stability and an efficient power sharing flow, represents a major challenge.
In order to solve this challenge, our colleagues from IREC – Institut de Recerca en Energia de Catalunya propose a sliding mode controller
(SMC) approach based on reduced order model. In order to build this model, topology-level power decoupling method has been used and the current transformer dynamics has been ignored.
It is shown that the designed controller guarantees an efficient power flow sharing and an accurate reference voltage tracking, and it proves a good robustness when the DC-bus voltage and loads are disturbed. A comparison with PI controller shown that shows the proposed controller has better
dynamic performance and good robustness against sudden load change than a linear one.
