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.
