Applied Power Electronics Conference

The IEEE Applied Power Electronics Conference (APEC) is the premiere conference for both researchers and practitioners in the power electronics field. It is jointly sponsored by PELS, IAS, and the Power Sources Manufacturers Association (PSMA). Dr. Kimball has been active in APEC since 2008, starting as publications chair, and later serving as a track chair. … Read more

Industry Applications Society

Since 2013, Dr. Kimball has served as the chairperson of the IAS Chapter of the St. Louis Section. The chapter has two technical meetings annually, held on the Missouri S&T campus in conjunction with the Rolla Sub-Section. If you would like to participate, either as a presenter or attendee, please contact Dr. Kimball.

The Solar Endowment

This project is sponsored by the US Department of Energy, as a subcontract via the Midwest Renewable Energy Association. The vision of this overall project (including other universities and organizations) is to construct solar energy projects on university campuses using innovative funding mechanisms.

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 ( 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
