Abstract:
(EN) There is provided a controller arranged to generate a duty cycle control signal (SD) for controlling an output voltage (Vout) of a switched mode power supply (100), SMPS, the SMPS being arranged to control its switching based on the duty cycle control signal and an oscillatory reference signal (Sref). The controller comprises : a first sampling module (150) arranged to sample a signal indicative of the output voltage of the SMPS at a first frequency that is higher than a frequency ( fref ) of the reference signal (Sref) to generate a first sampled signal (Sout); a filter module (160) arranged to filter out a ripple component (R) of the first sampled signal to generate a filtered signal (SF); a feedback control signal generator (170) arranged to generate, based on the filtered signal, at least one feedback control signal (SFB) for controlling the output voltage of the SMPS; a second sampling module (180) arranged to sample a signal indicative of an input voltage (Vin) of the SMPS at a second frequency that is higher than the frequency of the reference signal to generate a second sampled, signal (Sin); a feed- forward control signal generator (190) arranged to generate, based on the second sampled signal and a reference voltage, a feed-forward control signal (SFF) for controlling the output voltage of the SMPS; and a combining module (200) arranged to generate the duty cycle control signal based on the at least one feedback control signal and the feed-forward control signal.
(FR) L’invention concerne un dispositif de commande conçu pour générer un signal de commande (SD) permettant de commander une tension de sortie (Vout) d’une alimentation électrique (100) en mode commuté (SMPS), la SMPS étant conçue pour commander sa commutation sur la base d’un signal de commande de cycle de service et d’un signal de référence oscillant (SRef). Le dispositif de commande comprend : un premier module d'échantillonnage (150) conçu pour échantillonner un signal faisant état de la tension de sortie de la SMPS à une première fréquence qui est supérieure à une fréquence (fref) du signal de référence (Sref) pour générer un premier signal échantillonné (Sout) ; un module de filtre (160) conçu pour filtrer une composante d'ondulation (R) du premier signal échantillonné pour générer un signal filtré (SF) ; un générateur de signal de commande de rétroaction (170) conçu pour générer, en fonction du signal filtré, au moins un signal de commande de rétroaction (SFB) permettant de commander la tension de sortie de la SMPS ; un second module d'échantillonnage (180) conçu pour échantillonner un signal faisant état d'une tension d'entrée (Vin) de la SMPS à une seconde fréquence qui est supérieure à la fréquence du signal de référence pour générer un second signal échantillonné (Sin) ; un générateur de signal de commande prédictive (190) conçu pour générer, en fonction du second signal échantillonné et d'une tension de référence, un signal de commande prédictive (SFF) permettant de commander la tension de sortie de la SMPS ; et un module de combinaison (200) conçu pour générer le signal de commande de cycle de service sur la base dudit signal de commande de rétroaction et du signal de commande prédictive.
