La présente invention concerne un procédé de commande d'un contacteur électromagnétique. Elle concerne aussi un contacteur électromagnétique mettant en oeuvre un tel procédé. Le procédé consiste à alimenter l'électroaimant (9) du contacteur (4) par un signal d'alimentation à modulation de largeur d'impulsions (MLI) et présentant une fréquence nominale (Fch), le procédé consistant également à faire varier la période (T) sur au moins une partie des impulsions de la modulation de façon à réduire les perturbations électromagnétiques conduites, la variation de la période (T) étant choisie de façon à ce que la fréquence (F) du signal d'alimentation reste comprise dans une bande de fréquences donnée (BF) comportant la fréquence nominale (Fch).

| Embodiments of the present invention provide a power supply module and a soft start method. The power supply module includes an input detection circuit configured to output a first notification signal to a trigger drive circuit when it is determined that the power supply module receives a power supply signal; the trigger drive circuit configured to, upon receipt of the first notification signal sent from the input detection circuit, wait for a predetermined duration without sending a drive signal to a current limiting circuit, and to send the driver signal to the current limiting circuit when the predetermined duration elapses; and the current limiting circuit configured to limit a current on a Direct Current (DC) bus of the power supply module when the drive signal is not received by the current limiting circuit, and not to limit the current on the DC bus upon receipt of the drive signal. | ||||||
