Topic:Partial Power Converters for High-Efficiency DC Microgrids

As the global energy transition accelerates, DC microgrids are gaining traction as an efficient and flexible solution for integrating distributed energy resources, storage, and electrified loads. Within this evolving landscape, partial power converters (PPCs) are redefining how we think about energy conversion and system-level efficiency. Unlike conventional full-power converters, PPCs handle only a fraction of the total power flow, offering significant benefits in terms of reduced losses, lower semiconductor and cooling requirements, and improved power density. This keynote introduces the core principles of partial power processing and explains why it is a timely solution for renewable-heavy, cost-sensitive, and space-constrained DC systems.

Focusing on a few carefully selected applications, like photovoltaic string integration and second-life battery storage, the talk highlights the architectural trade-offs and control challenges that define the practical use of PPCs. Emerging topologies, protection strategies, and MPPT control near zero partiality are also touched upon.

This keynote aims to inspire broader consideration of PPCs as a practical and scalable design philosophy, offering new pathways for high-efficiency, resilient, and future-proof DC microgrids.
