A method and an apparatus for determining a turn-off negative voltage of a switching transistor are provided. The method includes: determining first and second turn-off negative voltage models; inputting acquired turn-off and turn-on gate resistances of the switching transistor, an acquired bus voltage, and an acquired minimum turn-on voltage of the switching transistor into the first model to obtain a turn-off negative voltage upper limit absolute value of the switching transistor; inputting the acquired turn-off and turn-on gate resistances of the switching transistor, the acquired bus voltage, and an acquired maximum bearable negative voltage absolute value of the switching transistor into the second model to obtain a turn-off negative voltage lower limit absolute value of the switching transistor; and determining a turn-off negative voltage interval of the switching transistor based on the turn-off negative voltage upper limit absolute value and the turn-off negative voltage lower limit absolute value.
A method for determining a turn-off negative voltage of a switching transistor, comprising:
An apparatus for determining a turn-off negative voltage of a switching transistor, comprising at least one hardware processor configured to:
