SiC Power Electronics for Grid and Transportation Applications

#control #sic #frequency

Power electronics is one of the key enabling technologies to achieve the goals of “Zero-Emission” transportation and high penetration renewables in the power grid. The wide bandgap (WBG) devices, and in particular SiC MOSFET devices, are transforming medium-voltage (MV) power conversion and control, presenting significant research opportunities. For example, the application of SiC devices can reduce or eliminate the need for interface harmonics filter in grid-tied inverters, however, leads to control challenges and worsens EMI. The SiC motor drives, while achieving higher efficiency and power density, can result in more serious reflective wave phenomena leading to machine insulation failure.

Additionally, driving SiC devices, especially MV SiC devices, remains a challenge. In this presentation, the speaker will introduce her group’s research work to address these challenges in the last decade using different approaches compared to state-of- the-art methods. An overview of the Center for Advanced Power System at Florida State University will also be introduced in this presentation.
