摘要

碳化硅功率开关器件在过去十年中取得了令人瞩目的进展。随着阻塞电压的增加,功率开关的电阻由漂移区主导,SiC相对于硅的优势增加。这可以通过SiC单极器件在10 kV左右的阻断电压下接近其理论极限的程度来说明。目前正在努力开发15-25千伏功率开关设备

Device options for high-voltage SiC power switching devices
Silicon carbide power switching devices have made remarkable progress in the past decade. As blocking voltage increases, the resistance of power switches becomes dominated by the drift region, and the advantage of SiC over silicon increases. This is illustrated by the degree to which SiC unipolar devices are approaching their theoretical limits at blocking voltages around 10 kV. Efforts are currently underway to develop power switching devices for the 15-25 kV regime
