[]Modular Multilevel Converters (MMCs) are pivotal in high-voltage applications such as HVDC transmission, renewable energy integration, and medium-voltage motor drives due to their modularity and superior controllability compared to conventional power conversion topologies. However, the bulky and costly capacitors in conventional submodules (SMs) of MMCs pose significant challenges in terms of volume, weight, and efficiency, often accounting for more than 50% of the converter’s weight and 80% of its volume. In this talk, Dr. Jinia Roy will present a novel SM circuit incorporating the Active Power Decoupling (APD) technique to address these limitations through advanced control and circuit design. The proposed APD-SM architecture operates on the principle of redistributing ripple power—predominantly at the line and twice the line frequency—into a dedicated decoupling path. This circuit provides a parallel route for oscillatory current components, effectively offloading stress from the main capacitor and enabling a significant reduction in its size. The APD-SM enables up to a sevenfold reduction in capacitor size while maintaining voltage ripple within acceptable limits. Additionally, it inherently reduces fault current, circulating current, and allowing for a more compact arm inductor design. The presentation will delve into the theoretical foundations, impedance-based analysis, and control strategies that validate the effectiveness of the APD-SM.

December 2025 Ex-Com Meeting - Online Virtual: https://events.vtools.ieee.org/m/519328

Grayson Randall, Chair of the 2025 IEEE Humanitarian Technologies Board, will share an exciting update on the IEEE MOVE USA Program. His presentation will highlight the program’s evolution, its current operations, and the strategic direction shaping its future. Grayson will review past deployments—showcasing how MOVE volunteers have supported communities during disasters—along with key lessons learned and how new technologies are expanding MOVE’s capabilities. He will also provide an overview of the program structure, the wide range of volunteer roles available, and how YOU can become part of this impactful effort. Whether you’re interested in STEM outreach, emergency response, technical operations, amateur radio, logistics, training, or behind-the-scenes support, there is a place for you in the MOVEment. This session is designed to inform, inspire, and help you take the next step toward becoming a MOVE USA volunteer and making a real difference when communities need it most.
