Abstract
A method for operating an electric drive apparatus (), wherein: the drive apparatus () comprises a electric machine () and power electronics () comprising a DC link capacitor () and a half bridge (), which has a first semiconductor switch (B) and a second semiconductor switch (B); the first semiconductor switch (B) is assigned a DESAT protection circuit (), a DESAT terminal () of the DESAT protection circuit () being electrically connected to an anode () of the first semiconductor switch (B); when a discharging specification is present, a discharging mode for discharging the DC link capacitor () is set. In the discharging mode, the first semiconductor switch (B) is switched and the second semiconductor switch (B) is alternately switched. In the discharging mode, the DESAT terminal () is electrically connected to a cathode () of the first semiconductor switch (B) to inhibit triggering of the DESAT protection circuit ().
