Seminar by Prof. Helen Li on SiC Power Electronics

Presentation title:
SiC Motor Drives and Active Reflective Wave Cancelation for “Zero-Emission” Transportation.

Place: Fredrik lamm
Time: 9th November, 13:00-14:30.

ABSTRACT
The wide bandgap (WBG) devices particularly SiC MOSFET devices, can help achieve high efficiency and high power density in high-power motor drives. However, the high dv/dt PWM voltage from the SiC devices causes huge voltage surges (2x the inverter voltage) at much shorter cables compared to the Si counter parts. These surges may lead to motor pre-mature failures from insulation breakdown, which is more crucial for electric ship and electric aircraft application where their high-power motor drives typically involve long cables. In this presentation, the speaker will introduce her research work on SiC motor drives and active reflective wave canceller to mitigate the voltage surges. An overview of Center for Advanced Power System at Florida State University will also be introduced in this presentation.
