  • Method for turning off an insulated gate bipolar transistor and apparatus for carrying out the method
    Publication number: 20020167826
    Abstract: What is specified is a method for turning off an insulated gate bipolar transistor (IGBT) (1), which is driven by means of a gate electrode driver stage (2) which applies the gate-cathode voltage (UGK) between gate electrode (G) and cathode (K), the anode-cathode voltage of the IGBT (1) being monitored for desaturation and, in the event of desaturation, an acknowledgement signal (SR) being output and fed to the gate electrode driver stage (2).
