Silicon carbide planar junctionless transistor for low-medium voltage power electronics

Silicon Carbide Power MESFET

Low voltage nanoelectromechanical switches based on silicon carbide nanowires.

We report experimental demonstrations of electrostatically actuated, contact-mode nanoelectromechanical switches based on very thin silicon carbide (SiC) nanowires (NWs). These NWs are lithographically patterned from a 50 nm thick SiC layer heteroepitaxially grown on single-crystal silicon (Si). Several generic designs of in-plane electrostatic SiC NW switches have been realized, with NW widths...

Silicon Carbide Power Device Characterization for HEVs

The emergence of silicon carbide(SiC-) based power semiconductor switches, with their superior features compared with silicon(Si-) based switches, has resulted in substantial improvement in the performance of power electronics converter systems. These systems with SiC power devices have the qualities of being more compact, lighter, and more efficient; thus, they are ideal for high-voltage power...

A Coordinated Control Scheme for Improving Voltage Quality Using Power Electronics Interfaced DGs

Recently, increasing of non-linear loads in the power distribution network has been increased harmonics in these networks. The harmonics problems get worse and complicated by installation of power factor correction capacitors and filters. But the Distributed Generations (DGs) interface inverters with properly control can help to improve power quality, harmonic compensation and voltage unbalance...

Silicon Carbide Based Transit Time Devices: The New Frontier in High-power THz Electronics

In recent years, the field of Terahertz (THz) science and technology has entered a completely new phase of unprecedented expansion that is generating ever-growing levels of broadbased international attention. Indeed, the plethora of activities that have arisen recently in both the technology and scientific arenas associated with the THz frequency domain i.e., between 1 millimeter (300 GHz) and ...
