Switching Voltage Transient Protection Schemes for High ...

Fault current shut off transients are more effectively protected by considerably slowing the rate of fall of fault current. Two novel protection schemes are introduced which protect IGBTs from potentially destructive voltage transients by slowing the rate of fall of fault current, only under fault ...
