An electric drive system for a vehicle. The electric drive system includes an inverter having at least one phase leg, wherein a first of the phase legs includes a first power switch; an internal voltage supply configured to generate a) an internal supply voltage regulated with respect to a voltage on a rail configured to be coupled to a dc power supply, and b) a second voltage, wherein the internal voltage supply is configured to reduce a voltage difference between the internal supply voltage and the second voltage in response to a signal indicating a shut-down or a fault of the vehicle; and a gate drive channel configured to drive the first power switch into conductance by applying the voltage difference between the internal supply voltage and the second voltage between a control terminal and a main terminal of the power switch, gate drive channel configured to continue the driving of the first power switch for a time window after the signal indicating the shut-down or the fault of the vehicle.
