Abstract
(EN) The present application relates to the technical field of power electronics, and provides a ripple detection apparatus and a ripple suppression apparatus. The ripple detection apparatus comprises a ripple sampling unit, at least two direct current (DC) sampling units, and a digital signal processing unit. The ripple sampling unit is configured to output to the digital signal processing unit a first voltage signal of an output port of a non-isolated DC/DC bidirectional energy conversion unit. The DC sampling units are configured to output to the digital signal processing unit a first DC signal in a second voltage signal of the port, of the connected non-isolated DC/DC bidirectional energy conversion unit, to which the DC sampling units are connected. An alternating current signal in the second voltage signal is blocked from being output to the digital signal processing unit. The digital signal processing unit is configured to determine a ripple noise signal of the output port of the non-isolated DC/DC bidirectional energy conversion unit according to the first voltage signal and the first DC signal.
(FR) La présente demande se rapporte au domaine technique de l'électronique de puissance et concerne un appareil de détection d'ondulation et un appareil de suppression d'ondulation. L'appareil de détection d'ondulation comprend une unité d'échantillonnage d'ondulation, au moins deux unités d'échantillonnage de courant continu (CC) et une unité de traitement de signal numérique. L'unité d'échantillonnage d'ondulation est conçue pour délivrer à l'unité de traitement de signal numérique un premier signal de tension d'un port de sortie d'une unité de conversion d'énergie bidirectionnelle CC/CC non isolée. Les unités d'échantillonnage de CC sont conçues pour délivrer à l'unité de traitement de signal numérique un premier signal CC dans un second signal de tension du port, de l'unité de conversion d'énergie bidirectionnelle CC/CC non isolée connectée, à laquelle les unités d'échantillonnage de CC sont connectées. La délivrance à l'unité de traitement de signal numérique d'un signal de courant alternatif dans le second signal de tension est bloquée. L'unité de traitement de signal numérique est conçue pour déterminer un signal de bruit d'ondulation du port de sortie de l'unité de conversion d'énergie bidirectionnelle CC/CC non isolée selon le premier signal de tension et le premier signal CC.
