P3: Selective Source AC/DC Power Supply

This project was supported by the US Environmental Protection Agency through grant SU836040¬†as part of their “People, Prosperity and the Planet” program (http://www.epa.gov/P3/). The goal was to design a power conversion system that would support both ac and dc loads from either solar power or the grid. The topology eliminates one power conversion in most … Read more

Waves, Wind, and Scavengers: Next Generation Renewable Energy Systems for Naval Applications

This project was funded by the Office of Naval Research. The project focused on a number of technologies to support next-generation hydrokinetic energy systems. Interest areas included: blade airfoil modeling, composite blade design & construction, embedded blade sensors, generator design, and power converter design. Kimball focused on the electromechanical energy conversion and grid interface.

Advanced Electric Drive Vehicles – A Comprehensive Education, Training, and Outreach Program

This project was sponsored by the US Department of Energy. Along with our partners, University of Central Missouri, Linn State Technical College, and the St. Louis Science Center, we developed a number of educational offerings related to electric drive vehicles. Kimball’s contribution centered on the development of a hardware-in-the-loop system to demonstrate a series hybrid … Read more

EISG: Module-Level Power Converters for Parallel-Connected Photovoltaic Arrays

This work was funded by the California Energy Commission. As in the NSF-sponsored project on SC converters, the goal of this project was to improve energy harvesting from PV panels in an array that are¬†subject to differential shading. Rather than use an SC converter, though, a transformer-based approach was used. A number of topologies were … Read more

The Future Renewable Electric Energy Delivery and Management (FREEDM) Systems Center

FREEDM is an NSF-funded ERC (award 0812121). For more details, consult www.freedm.ncsu.edu. Dr. Kimball was previously involved in the design of alternative topologies for the solid state transformer, and in system modeling. His current focus is an invariant-based approach to cyber-physical correctness. In essence, the correctness of the physical system (in this case, the power … Read more

REU Site: Technologies for Renewable Energy Generation and Management

This project is funded by the National Science Foundation under award 1157001 with a start date of June 1, 2012. Collaborators include Stuart Baur, Joel Burken, Curt Elmore, and Mehdi Ferdowsi. See also power.mst.edu/reu. The objective of this three year REU Site program at Missouri University of Science and Technology is to engage ten undergraduate … Read more

Improved Photovoltaic Arrays with Local Switched-Capacitor Converters

This award was funded by the National Science Foundation (award 0900940) under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The performance period was September 2009 through August 2013. The objective of this research is to improve residential photovoltaic installations with switched-capacitor power converters. The approach considers a system topology in which … Read more
