description The invention relates to the technical field of high-voltage power transmission, and discloses an IGBT overvoltage protection device and method, and the device comprises a controller, an overvoltage judgment unit, a voltage collection unit, and a drive circuit. The voltage collection unit is used for collecting the voltage between the collector electrode and the emitter electrode of an IGBT; the overvoltage judgment unit is used for comparing the acquired voltage with a plurality of reference voltages and then outputting a plurality of overvoltage judgment results; the driving circuit is used for controlling the on-off of the IGBT based on the driving signal; after the controller judges the current operation condition of the IGBT, an overvoltage judgment result corresponding to the current operation condition is selected, and the drive circuit is driven to carry out overvoltage protection on the IGBT based on the overvoltage judgment result. According to the invention, the corresponding voltage comparison res
