Abstract
(EN) A power adapter. The power adapter comprises an electric energy conversion unit (20) and a clamping unit (21). The electric energy conversion unit (20) is used for performing alternating-current-to-direct-current conversion on alternating-current electric energy, or for performing direct-current conversion on pulsed direct-current electric energy formed after the alternating-current electric energy is rectified; and the clamping unit (21) is connected to an input end and an output end of the electric energy conversion unit (20), so as to control, when the difference value between an input end voltage and an output end voltage of the electric energy conversion unit (20) is greater than or equal to a first difference value, the electric energy conversion unit to reduce an output voltage. The present invention improves the adaptability of the power adapter used in external power supply environments having different quality, and improves the working stability of the power adapter. (FIG. 1)
(FR) Adaptateur d'alimentation. L'adaptateur d'alimentation comprend une unité de conversion d'énergie électrique (20) et une unité de serrage (21). L'unité de conversion d'énergie électrique (20) est utilisée pour effectuer une conversion courant alternatif-courant continu sur l'énergie électrique à courant alternatif, ou pour effectuer une conversion de courant continu sur l'énergie électrique à courant continu pulsé formée après que l'énergie électrique à courant alternatif a été redressée; et l'unité de serrage (21) est connectée à une extrémité d'entrée et à une extrémité de sortie de l'unité de conversion d'énergie électrique (20), de manière à commander à l'unité de conversion d'énergie électrique, lorsque la valeur de différence entre une tension d'extrémité d'entrée et une tension d'extrémité de sortie de l'unité de conversion d'énergie électrique (20) est supérieure ou égale à une première valeur de différence, de réduire une tension de sortie. La présente invention améliore l'adaptabilité de l'adaptateur d'alimentation utilisé dans des environnements d'alimentation électrique externe ayant une qualité différente, et améliore la stabilité de fonctionnement de l'adaptateur d'alimentation.
