Abstract
(EN)
This invention relates to a dead time control method (100) comprising the steps of: converting the DC link voltage, output current and output voltage to digital values with an ADC (Analog to Digital converter) (102); calculating the hysteresis band for adaptive hysteresis current control using the values read by the ADC and updating the band value via recalculating it at each sampling time (103); calculating the IrefH and IrefL values using the hysteresis band and Iref (l03a); generating the PWM signal by hysteresis current control (104), generating two auxiliary control signals as VP, VN (105); in the region where VP = 1 and VN = 0, applying of the drive signal of Ti without setting dead time wherein Ti is the conduction duration of an upper switch, and not applying the drive signal of T2 wherein T2 is the turn off duration of said upper switch and is the conduction duration of a lower switch (106); Applying the driving signal of T2 without setting dead time in the region where VP = 0 and VN = 1, and not applying the driving signal of Ti (107); applying the driving signals of Ti and T2 via setting dead time in the region where VP = 1 and VN = 1, (108); and relates to also circuits (2, 2', 2") on which this method (100) is applied for hysteresis current control in power electronics converters.

La présente invention concerne un procédé (100) de commande de temps mort comprenant les étapes consistant à : convertir la tension de liaison CC, le courant de sortie et la tension de sortie en valeurs numériques avec un convertisseur analogique-numérique (CAN) (102) ; calculer la bande d'hystérésis pour une commande de courant d'hystérésis adaptative à l'aide des valeurs lues par le CAN et mettre à jour la valeur de bande par l'intermédiaire d'un nouveau calcul de celle-ci à chaque instant d'échantillonnage (103) ; calculer les valeurs IrefH et IrefL à l'aide de la bande d'hystérésis et Iref (103a) ; générer le signal PWM (modulation d'impulsions en largeur) par commande du courant d'hystérésis (104), générer deux signaux de commande auxiliaires en tant que VP, VN (105) ; appliquer, dans la région où VP = 1 et VN = 0, le signal d'attaque de Ti sans régler le temps mort, Ti représentant la durée de conduction d'un commutateur supérieur, et ne pas appliquer le signal d'attaque de T2, T2 représentant la durée d'arrêt dudit commutateur supérieur et représentant la durée de conduction d'un commutateur inférieur (106) ; appliquer le signal d'attaque de T2 sans régler le temps mort dans la région où VP = 0 et VN = 1, et ne pas appliquer le signal d'attaque de Ti (107) ; appliquer les signaux d'attaque de Ti et T2 par l'intermédiaire du réglage du temps mort dans la région où VP = 1 et VN = 1, (108) ; et concerne également des circuits (2, 2', 2 ") sur lesquels ce procédé (100) est appliqué pour une commande de courant d'hystérésis dans des convertisseurs électroniques de puissance.
