Design and Control of a Two-Phase Interleaved DC-DC Boost Converter with Constant Power Load for More Electric Aircraft

In this study, a two-phase interleaved synchronous DC-DC boost converter with a CPL (constant power load) in an MEA (more electric aircraft) system was extracted and analyzed. In addition, a backstepping control based on the extracted model is created to assure the system's stability when tracking the required bus voltage in the MEAs. The demand for stable and efficient power converters capable of supplying CPLs in MEA microgrids is growing as aviation shifts from traditional to more electric systems to boost efficiency. The design in this paper is intended to increase power density, improve thermal performance, and reduce current ripple to reduce energy losses. Other criteria such as reliability and efficiency are also considered in the design. In this study, MATLAB simulation was used to analyze the behavior of the converter, the proposed model, and the controller. The results show that by combining the advantages of accurate modeling with interleaved topologies, this method provides a suitable reliable power conversion solution and reliable control for MEA systems. This study contributes to MEA technology by presenting a realistic and high-performance solution that meets the critical requirements for efficiency, dependability, and cost-effectiveness.
