Title (EN) DIGITAL CONTROL OF SWITCHED BOUNDARY MODE POWER CONVERTER WITHOUT CURRENT SENSOR
(FR) COMMANDE NUMÉRIQUE DE CONVERTISSEUR DE PUISSANCE À MODE LIMITE COMMUTÉ SANS CAPTEUR DE COURANT
Abstract:
(EN) A circuit arrangement for switched boundary mode power conversion, a corresponding signal processor and a method of switched boundary mode power conversion are provided. The circuit arrangement comprises an input for receiving an input voltage from a power supply, an output to provide an output voltage to a load, an energy storage device, a controllable switching device, and a signal processor. The signal processor is connected to the controllable switching device and being configured for zero-current switching of the switching device, wherein the signal processor is further configured to determine at least one switching point for the zero-current switching from a first voltage signal and a second voltage signal, wherein the first voltage signal corresponds to the input voltage and the second voltage signal corresponds to the output voltage.
(FR) L'invention concerne un ensemble circuit permettant une conversion de puissance en mode limite commuté, un processeur de signal correspondant et un procédé de conversion de puissance en mode limite commuté. L'ensemble circuit comprend une entrée permettant de recevoir une tension d'entrée provenant d'une alimentation électrique, une sortie permettant de fournir une tension de sortie à une charge, un dispositif de stockage d'énergie, un dispositif de commutation commandable, et un processeur de signal. Le processeur de signal est connecté au dispositif de commutation commandable et est configuré pour une commutation à courant nul du dispositif de commutation, et en outre configuré de façon à déterminer au moins un point de commutation en ce qui concerne la commutation à courant nul à partir de premier et second signaux de tension, le premier signal de tension correspondant à la tension d'entrée et le second signal de tension correspondant à la tension de sortie.
