SiC MOSFETs Gate Driver with Minimum Propagation Delay Time and Auxiliary Power Supply with Wide Input Voltage Range for High Temperature Applications
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Low propagation delay time is essential for SiC drivers at high frequency. The propagation delay time of the commercial parts are normally over 100 ns. A signal isolation circuit and a level shifting circuit are proposed and applied in SiC drivers with minimum propagation delay...

Ultra-wide temperature range (-30/spl sim/70 /spl deg/C) operation of athermal AWG module using pure aluminum plate
2006 Edition, January 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We have elucidated an origin of a temperature dependence of a center wavelength in an athermal AWG and demonstrated an ultra-wide temperature range (-30/spl sim/70 /spl deg/C) operation using a pure aluminum plate for the first time.

An Improved Proportional Base Driver for Minimizing Driver Power Consumption of SiC BJT over Wide Current and Temperature Range
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

SiC BJT still offers an attractive alternative to the more popular SiC MOSFET because of its several advantages, such as low fabrication cost, fast switching speed, and high temperature durability. However, it has not been widely accepted in the market partially because the...
