    3 Phase Half Bridge Driver Protection Components

    You can use autoprotect mosfet. In short-break the IRF have a applications that uses the voltage peak of the MOSFET when stop driving for protect the mosfet against high current. My English is not so good but I hope you can understand, if you want I can put the circuit in my site. Edson
