Title

Abstract
(EN)
A method for regulating input impedance of a switching regulator, the method comprising: obtaining, at an impedance controller: (a) a measured voltage value that is indicative of an input current of the switching regulator and (b) an input voltage of the switching regulator, wherein a ratio of the input voltage to the input current defines an actual input impedance of the switching regulator; generating a control signal by the impedance controller, in accordance with a difference between the actual input impedance of the switching regulator and a desired input impedance of the switching regulator, wherein the desired input impedance is a predefined impedance; and controlling a feedback node feeding the switching regulator, in accordance with the control signal, to realize an output voltage of the switching regulator for achieving the desired input impedance, wherein the feedback node is external to the switching regulator, thereby regulating the input impedance of the switching regulator externally to the switching regulator.

L'invention concerne un procédé de régulation de l'impédance d'entrée d'un régulateur de commutation, le procédé comprenant les étapes suivantes : obtention au niveau d'un dispositif de commande d'impédance : (a) d'une valeur de tension mesurée qui indique un courant d'entrée du régulateur de commutation et (b) d'une tension d'entrée du régulateur de commutation, un rapport entre la tension d'entrée et le courant d'entrée définissant une impédance d'entrée réelle du régulateur de commutation; génération, par le dispositif de commande d'impédance, d'un signal de commande, conformément à une différence entre l'impédance d'entrée réelle du régulateur de commutation et une impédance d'entrée souhaitée du régulateur de commutation, l'impédance d'entrée souhaitée étant une impédance prédéfinie; et commande d'un nœud de rétroaction alimentant le régulateur de commutation, conformément au signal de commande, afin de réaliser une tension de sortie du régulateur de commutation pour obtenir l'impédance d'entrée souhaitée, le nœud de rétroaction étant externe au régulateur de commutation, régulant ainsi l'impédance d'entrée du régulateur de commutation à l'extérieur du régulateur de commutation.
