ABSTRACT:
The invention concerns a process for control of the opening of a power interrupter, especially a transistor, at a determined instant, regardless of the particular characteristics of the interrupter. According to the invention, the emission of the normal closing command (A) of the interrupter is terminated at a determined time interval before the said determined instant, and in its place is emitted an additional closing command (G) with a duration equal to the difference between the said interval and the actual time required by the interrupter to pass from the closed state to the open state. Preferably, the actual time required by the interrupter to change state is determined during its preceding passages from the closed state to the open state.
