Abstract:
(EN) The present invention relates to a method and system for reducing switching noise in a charging device, and a non-transitory computer-readable recording medium. According to an aspect of the present invention, a method for reducing switching noise in a charging device is provided, the method comprising: a step of sensing an output current signal; and a step of controlling the switching frequency of the charging device on the basis of the output current signal, wherein, in the step of controlling the switching frequency, the switching frequency is controlled such that: when the magnitude of the output current signal is equal to or less than a first magnitude, the switching frequency is linearly increased; when the magnitude of the output current signal exceeds the first magnitude, the switching frequency is fixed to a switching frequency at the time when the output current signal has the first magnitude, and is maintained at the same; and when the magnitude of the output current signal exceeds a second magnitude, the switching frequency is linearly increased at a lower rate of increase than the rate of increase at which the switching frequency is increased when the magnitude of the output current signal is equal to or less than the first magnitude.
(FR) La présente invention concerne un procédé et un système pour réduire le bruit de commutation dans un dispositif de charge et un support d’enregistrement lisible par ordinateur non temporaire. Le procédé de réduction du bruit de commutation dans un dispositif de charge selon un aspect de la présente invention comprend : une étape de détection d'un signal de courant de sortie ; et une étape de commande de la fréquence de commutation du dispositif de charge sur la base du signal de courant de sortie. Dans l'étape de commande de la fréquence de commutation, la fréquence de commutation est commandée de telle sorte que : lorsque l'amplitude du signal de courant de sortie est égale ou inférieure à une première amplitude, la fréquence de commutation est augmentée linéairement ; lorsque l'amplitude du signal de courant de sortie dépasse la première amplitude, la fréquence de commutation est fixée à une fréquence de commutation au moment où le signal de courant de sortie présente la première amplitude et elle est maintenue à celui-ci ; et lorsque l'amplitude du signal de courant de sortie dépasse une deuxième amplitude, la fréquence de commutation est augmentée linéairement à une vitesse d'augmentation plus basse que la vitesse d'augmentation à laquelle la fréquence de commutation est augmentée lorsque l'amplitude du signal de courant de sortie est égale ou inférieure à la première amplitude.
