Abstract

See full text

An electric drive system for a vehicle 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 an internal supply voltage regulated with respect to a voltage on a rail and 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; 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 duration after the signal indicating the shut-down or the fault.
