Abstract:
1. A process for controlling an electronic power component comprising a piloting process for piloting an opening and a closing of the electronic power component, said piloting process having a plurality of steps for controlling an application of a succession of different commutation voltages on a control electrode of the electronic power component between an instant when said piloting process begins and an instant when either the opening and the closing of the electronic power component should be completed, wherein passage from one commutation voltage to a successive commutation voltage in said piloting process is effected automatically as soon as a corresponding condition of passage is satisfied, said piloting process including the steps of: reading a value of at least one operational parameter characteristic of a reaction of the electronic power component in response to a commutation voltage, verifying, based on the values read, whether the reaction of the electronic power component to the commutation voltage is produced within a predetermined time for the commutation voltage, if the reaction of the electronic power component is produced within the predetermined time for the commutation voltage, allowing said piloting process to continue to a successive commutation voltage, and if the reaction of the electronic power component is not produced within the predetermined time for the commutation voltage, interrupting said piloting process and triggering off a process for safeguarding the integrity of the electronic power component.
