Abstract
The process for controlling an electronic power component for piloting an opening and/or closure of this component. The piloting process includes a plurality of steps for controlling the application of a succession of different commutation voltages on a control electrode of the electronic power component between an instant when the piloting process begins and an instant when either the opening or the closure of the electronic power component is to stop. Passage from one commutation voltage to a successive commutation voltage in this piloting process is automatically effected as soon as a corresponding condition of passage is satisfied. The process further includes a step of interrupting the piloting process and immediately triggering off a process for safeguarding the integrity of the electronic power component if the component does not react to a commutation voltage within a predetermined time for the commutation voltage.
