Assistant Lecturer Mahmoud Suwadi, a faculty member in the Department of Electrical Engineering at the University of Baghdad’s College of Engineering, has published a distinguished scientific paper titled “Lifetime-Based Discontinuous PWM for Cascaded H-Bridge Converters”, in collaboration with an international research team. The paper appeared in IEEE Access, a first-quartile (Q1) journal indexed in the Scopus database, with a 2024 Impact Factor of 3.9 and a CiteScore of 9.8.
The research proposes the development of a novel Discontinuous Pulse Width Modulation (DPWM) algorithm that is based on the operational lifespan of electronic components. The goal is to enhance the efficiency and reliability of Cascaded H-Bridge (CHB) converters used in medium- and high-voltage applications, such as integrating solar and wind energy systems into electrical grids.
The study was grounded in precise mathematical modeling, advanced computer simulations, and experimental results that demonstrated the effectiveness of the proposed method in reducing maintenance costs and boosting the performance of multilevel converter systems.
This achievement marks a significant contribution to the field of power electronics and intelligent control, reflecting the advanced level of scientific research at the college.
Moreover, this initiative supports two Sustainable Development Goals: Goal 4, which advocates for quality education, and Goal 17, which promotes partnerships to achieve the goals.
