The present invention proposes a method for adjusting a parameter (IDQ) of a power device (1) by changing an input signal (VG) to said power device, said method comprising the steps of taking (S2) a sample of an output signal (POUT) of said power device (1), detecting (S5) at least a first and a second signal component level (P1ST, P2ND) of said sampled output signal (POUT), processing (S6) the at least detected first and second signal component level (P1ST, P2ND), deciding on the basis of a result obtained in said processing step (S6), whether a compensation of a change of said parameter (IDQ) is required, and if such a change is to be compensated, determining (S8) a changing value (V) for said input signal (VG) and adjusting (S9) the parameter (IDQ) by changing said input signal (VG) by said determined changing value (V). Furthermore, the present invention proposes a corresponding device.

L'invention concerne un procédé d'ajustement de paramètre (IDQ - courant de drain de repos) propre à un dispositif de puissance (1) qui vise à modifier un signal d'entrée (VG -tension de grille) destiné à ce dispositif. Le procédé comprend les étapes suivantes : collecte (S2) d'un échantillon de signal de sortie (POUT) du dispositif de puissance (1); détection (S5) d'au moins un premier niveau et un second niveau de composante de signal (P1ST, P2ND) dudit signal de sortie échantillonné (POUT); traitement (S6) des niveaux de composante de signal susmentionnés (P1ST, P2ND); à partir du résultat de ce traitement (S6), détermination de la nécessité d'une compensation correspondant à une modification du paramètre (IDQ), et si cette compensation s'impose, détermination (S8) d'une valeur de modification (V) pour le signal d'entrée (VG) puis ajustement (S9) du paramètre (IDQ) par modification du signal d'entrée (VG) selon la valeur de modification déterminée (V). L'invention concerne également un dispositif de puissance correspondant.
