PowerAmerica to run Webinar on SiC


On October 28th, Dragan Maksimovic will present a talk called 'Optimisation of a 125 kW SiC Composite Converter for Electric Drivetrain Applications' about his research

On Thursday, October 28, 2021, from 12 pm. to 1pm ET, Dragan Maksimovic will present a zoom talk 'Optimisation of a 125 kW SiC Composite Converter for Electric Drivetrain Applications' about his research. This is in the latest installment of the PowerAmerica Institute's monthly webinar series.

This webinar is focused on converter optimisation in electric drivetrain applications. Maksimovic will show how the impact of wide bandgap device characteristics can be amplified by advances in converter and system architectures, soft switching techniques, control methods, and electro-thermal co-design.

In electric drivetrain architectures, including xEV and electrified aircraft applications, a boost dc-dc converter can be used to interface a battery system to variable-speed ac drives, thus enabling the system operation at increased dc bus voltages. Using standard boost converter realizations, it has been shown how SiC devices lead to improvements in efficiency and reductions in the size of magnetic components.

This webinar will show how further improvements can be achieved using composite architectures where SiC device and passive component stresses and losses are substantially reduced.

Composite converter optimisation involves complex design tradeoffs in terms of losses, size, and reliability. To address these challenges, a scalable design methodology is presented, which involves the converter architecture, magnetics design, control techniques, and electro-thermal co-design. The approach is illustrated by modeling, simulations, and experimental results on a 125 kW SiC composite converter prototype featuring 21.3 kW/L power density and 99% drive-cycle weighted efficiency.

Bio: Dragan Maksimovic received his BSc. and MSc from the University of Belgrade in Serbia in 1984 and 1986, respectively, and his PhD from the California Institute of Technology in 1989. Since 1992, he has been with the University of Colorado at Boulder, where he is currently a Professor and Director of the Colorado Power Electronics Center (CoPEC).

He has co-authored over 300 papers, and two textbooks, Fundamentals of Power Electronics, and Digital Control of High-Frequency Switched-Mode Power Converters.
