Advanced Protection for Silicon Carbide (SiC) Power Semiconductors

Protecting the power semiconductor is a continuous process and AgileSwitch Gate Drivers have a unique capability in this regard. The driver boards from AgileSwitch are able to reduce the stress on the Power Semiconductor while reducing switching losses, through the use of Augmented Turn-Off

Under normal operating conditions, the gate voltage in a turn-off cycle steps through an intermediate level before reaching the off voltage level. Under short circuit conditions, the gate voltage steps through multiple intermediate levels before reaching the off voltage level.

A detailed explanation of the benefits of Augmented Turn-Off can be found here.

In addition to this continuous process, what else do we protect against?

• Power Supply Under Voltage or Over Voltage
• Over Current (Short Circuit)
• Overtemperature 
• DC Link Overvoltage
