Abstract:

Power converters play a critical role in the operation of electric vehicles. A standard practice of power converter design is to use peak power as the operating point for power converter sizing. However, most operating points of electric vehicles are at power lower than the peak power, resulting in sub-optimal performance and overall lower efficiency in the driving life cycle. This paper presents a power converter sizing approach based on distributed operating power. The mathematical framework for this proposed approach is presented and compared with the conventional peak power design. Simulation results validate our claim.
