In recent decades, we have witnessed the emergence of an electric grid that is increasingly decentralized and is capable of reliably integrating renewable resources that are distributed and intermittent in nature. While this important trend continues with the electric grid, there is growing need for a similar decentralization of electric networks in a variety of high-impact emerging applications, including all-electric aircraft and ships, data centers, smart buildings, and application processors. Many of these applications have faster dynamics and lower inertia than an electric grid, and, combined with requirements for high performance and high reliability, will require fundamentally new power conversion architectures that are highly resilient, scalable, and efficient. This talk presents contributions in decentralized optimization and control for power conversion circuits and systems that lay the foundation for a new class of electric networks that can be scaled from the bottom-up. First, I will discuss new design techniques for power conversion circuits that operate in tandem with each other to improve power quality and efficiency. Second, I will discuss our work on power conversion systems that can actively detect and diagnosis faults, essentially acting as probes within networks, enabling improvements in reliability and resiliency. I will conclude by discussing future directions in the interdisciplinary design of power conversion circuits and systems that can support and synthesize decentralized electric networks.
