This paper discusses about robustness evaluation of SiC MOSFETs under avalanche working conditions. Capability to sustain previous operating conditions, is required especially for power converters applied for electric traction. Indeed, possible failure of devices during freewheeling conduction or wrong gate driver command signals can involve converter power devices in avalanche. Therefore, experimental tests have been […]
As conventional silicon-based MOSFETs mature, they are now reaching their theoretical limits of performance. Wide band-gap semiconductor devices represent an interesting alternative for improving performance due to their electrical, thermal, and mechanical properties.

The device is a high voltage converter smartly integrating an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V breakdown voltage allows the extended input voltage range to be applied, as well as the size of the DRAIN snubber circuit to be reduced. The admin of this site […]
The most advanced 40V power MOSFETs from STMicroelectronics properly fulfill all the mechanical, environmental and electrical characteristics requested by automotive safety systems, such as EPS (Electric Power Steering) and EPB (Electric Park Brake). These electro-mechanical systems have to be compliant to the automotive AEC Q101 specifications and, specifically, the low voltage MOSFETs have to sustain […]
