On the morning of May 30, a delegation from the University of Seville, Spain, was invited to visit the Department of Electrical Engineering and Applied Electronics (EEA) and delivered an academic report in Meeting Room 102, Zone 3 of the West Main Building. The report was titled “Advanced Modulation and Control Techniques to Enhance the Power Converters Performance.” The session was chaired by Professor Li Yongdong from EEA.

The report highlighted that improving the performance of power converters is a broad topic that involves various issues depending on the application, such as minimizing common-mode voltage, optimizing harmonic performance, and extending the lifespan of power devices. The presentation addressed these issues from a theoretical perspective and proposed simple methods to enhance converter operational performance.

The report was jointly presented by Professors Leopoldo G. Franquelo and Jose I. Leon from the University of Seville. Professor Franquelo (IEEE Life Fellow) obtained his PhD in Electrical Engineering from the University of Seville in 1980. His current research focuses on modulation techniques for multilevel inverters and applications of power electronics in renewable energy systems. Professor Leon's primary research areas include modulation and control of power converters for high-power applications and renewable energy systems.

Following the report, the delegation visited the “Gongzi Hall, where they were received by university and department leaders.
