Medium-Voltage Silicon Carbide Super Junctions Transistors

In this project, a team at GE Research plans to develop the world’s 1st high voltage SiC super junction (SJ) metal-oxide-semiconductor field effect transistor (MOSFET) that enables highly-efficient power conversion for next generation MVDC and HVDC grids as well as other applications in energy, aviation and healthcare.

Specific on-resistance of drift layer vs. breakdown for Si and SiC unipolar devices


Project Impact

The goal of this project is to develop and demonstrate high voltage SiC SJ MOSFETs that can provide breakthroughs in power conversion efficiency and system simplification across many MV applications including, renewables, utility grid-connected MVDC/HVDC, and converters used in the aviation and healthcare sectors.
