Abstract: There is described a method for driving paralleled electronic switches via a drive signal processing circuit (1) connected to respective driver circuits (5A, 5B) associated with said electronic switches (7 A, 7B). During the turn-off intervals of the electronic switch, the driver circuit sends a fault signal to the drive signal processing circuit. During the turn-off intervals of the electronic switch, the driver circuit masks the fault signal coming from the drive circuit of the electronic switch.
