About
Miad Ahmadi holds a Ph.D. from Delft University of Technology (TU Delft), where his research focused on the reliability of Modular Multilevel Converters (MMCs) from component-level to system-level perspectives. His doctoral work revolved around three key concepts: redundancy, modularity, and reconfigurability. This research journey allowed him to develop deep expertise in power electronics and reliability engineering while tackling both theoretical and practical challenges. Throughout his Ph.D., he gained extensive experience in PCB design, experimental validation, reliability-oriented design methodologies, and the economic evaluation of reliability improvements through CAPEX and OPEX analyses. He also supervised M.Sc. students and published several articles in leading peer-reviewed journals. Currently, He works as a Commissioning and Start-Up Engineer at Hitachi Energy, where he is involved in high- and medium-voltage AC projects. His responsibilities include developing control and protection concepts, programming protection relays using PCM600, preparing and executing FAT and SAT protocols, and contributing to the financial and commercial aspects of projects. His career has provided him with the unique opportunity to gain experience in both academia and industry. This combination of research excellence and hands-on project execution within a pioneering global electrical engineering company has enabled me to bridge the gap between innovative ideas and practical implementation.
