Critical Need: 

Electricity generation currently accounts for ~40% of primary energy consumption in the U.S. and continues to be the fastest growing form of end-use energy. Power electronics condition, control, and convert electrical power in order to provide optimal conditions for transmission, distribution, and load-side consumption. Most of today's power electronics have limitations to their performance, temperature resilience, and size due to the circuit topology and semiconductor power devices used. Emerging semiconductor devices such as those based on wide-bandgap materials -- along with transformative advances in circuit design and system architecture -- present opportunities to dramatically improve power converter performance while reducing size and weight. Development of advanced power electronics with unprecedented functionality, efficiency, reliability, and form factor will help provide the U.S. a critical technological advantage in an increasingly electrified world economy.

Project Innovation + Advantages: 

The University of Colorado, Boulder (CU-Bolder) and its project team will develop new composite SiC power converter technology that achieves high power and voltage conversion (250 VDC to 1200 VDC) in a smaller package than ever achieved due largely to improved switching dynamics and reduced need for large passive energy storage components. Also, utilizing higher system voltage in vehicular power systems has been proven to enable vehicle manufacturers to use thinner and lighter wires and improve vehicle powertrain system efficiency. The team seeks to demonstrate the power converter as an on-board, high-power, multifunctional system for both charging electric vehicles and providing power to the motor. The project will lead to experimental demonstration of a 100 kW multifunction electric vehicle power conversion system that includes integrated wired charging and wireless charging functions. If successful, the CU-Boulder team will make important progress towards reducing the size, cost, and complexity of power systems associated with electric vehicles.

Potential Impact: 

If successful, CIRCUITS projects will enable further development of a new class of power converters suitable for a broad range of applications including motor drives for heavy equipment and consumer appliances, electric vehicle battery charging, high-performance computer data centers, grid applications for stability and resilience, and emerging electric propulsion systems.

Security: 

More robust power electronics that withstand higher operating temperatures, have increased durability, a smaller form factor, and higher efficiency will significantly improve the reliability and security of a resilient electrical grid.

Environment: 

Low cost and highly efficient power electronics could lead to more affordable electric and hybrid-electric transportation, greater integration of renewable power sources, and higher efficiency electric motors for use in heavy industries and consumer applications.

Economy: 

Electricity is the fastest growing form of end-use energy in the United States. High performance, low cost power electronics would enable significant efficiency gains across the economy, reducing energy costs for businesses and families.
