Professor Chapman’s research addresses a variety of problems in the areas of power and energy management. Broad topics of research include power electronics, solar power, wind power, solar home design, electric drives, electric machines, and power integrated circuits. His research group conducts both theoretical and experimental work. The theoretical work usually focuses on modeling and optimization, as well as advanced simulation techniques for energy devices and systems.
His research team has addressed power management from the range of milliwatts to kilowatts. At the low power end, Prof. Chapman’s team has investigated complete power circuit integration techniques for micro power sources, such as may be used in energy harvesting devices. At higher power, we have focused on inverters for solar power, motor drives, and fuel cell power supplies. His team has also addressed all aspects of power electronics and machines for energy applications. In addition to experimental work, they have devoted much effort to simulation techniques and optimization procedures.
As portable electronics and autonomous systems shrink in size and expand in functionality, energy sources and associated electronics are becoming a greater fraction of the form factor, cost, and mass of the system. For this reason, future research efforts must focus on a multidisciplinary, system-level optimization and design. To facilitate implementation, Prof. Chapman’s group will continue to push switching frequencies higher to further reduce size while improving performance, for example, by utilizing new semiconductor materials and devices, as well as innovating in the areas of passive component design.
Now and certainly in the future, nearly every kilowatt-hour of grid electricity will pass through at least one power converter. Therefore, even a one-percent improvement in overall efficiency could save billions of dollars in fuel costs and significantly reduce environmental impact. Likewise, the same is true for energy efficient or “zero energy” housing, which saves homeowners money while reducing loads on already stressed power grid. With today’s emphasis on sustainable electric power and transportation, energy efficiency in power electronics is an important part of Professor Chapman’s plan for future research.
