Events for May 21, 2026

Join the IEEE Power Electronics Society (PELS) for an informal technical discussion with Dr. Bowen Yang on emerging power architectures for AI data centers. Dinner will be provided, along with time for networking with local engineers and professionals. As demand for AI computing continues to grow, data centers are exploring new approaches to power distribution—particularly the transition from medium-voltage (MV) systems to low-voltage DC (LVDC) buses such as 800V DC. Solid-state transformers (SSTs) are one of the technologies being considered to enable this shift. This session will be an open, high-level conversation rather than a formal presentation. Topics may include: - The role of SSTs in future data center power architectures - Considerations when moving from MV systems to 800V DC distribution - Reliability and controllability in power-electronics-based systems - Practical challenges, tradeoffs, and industry perspectives Attendees are encouraged to ask questions, share experiences, and engage in the discussion.

Join the IEEE PES/IAS Denver Chapter for our May meeting. Note that this event is at the Original Brooklyn's at 2644 W Colfax Ave, Denver, CO 80204. Schedule 6:00 – Check-in, Chapter Business and Networking 6:30 – Dinner Served 7:00 – Presentation/Networking 8:00 – Adjourn Speaker: Nathan Kassees, PE Title: Grounding Transformers in the Power Grid: Design, Protection, and Best Practices Summary: This presentation will review the requirements and theory of grounding transformers. Grounding transformers are used throughout the power grid as a means to provide protective relaying visibility of ground faults. However, if installed incorrectly they can interfere with protection schemes, create excessive fault current, and allow excessive ground fault overvoltage. The review will include the system conditions that require a grounding transformer, symmetrical component theory, protection requirements, types of grounding transformers, and some examples.
