Claim:
1. A device for driving paralleled electronic switches, comprising: a drive signal processing circuit configured to send a drive signal to a plurality of parallel electronic switches, the drive signal having at least a turn-on value and a turn-off value; a driver circuit for each of the plurality of electronic switches, each driver circuit configured to receive the drive signal from the drive signal processing circuit and control closing and opening of a respective electronic switch as a function of the value of the drive signal; a drive line configured to transmit the drive signal from an output of the drive signal processing circuit to an input of a respective driver circuit; a fault line configured to transmit a fault signal from the respective driver circuit to the drive signal processing circuit; wherein each driver circuit is configured to generate a fault signal on the fault line when the drive signal input to the driver circuit assumes the turn-off value, and when there is a fault in the respective electronic switch; and wherein the drive signal processing circuit is configured to mask the fault signal from the respective driver circuit during intervals in which the drive signal output from the drive signal processing circuit assumes the turn-off value.
