Abstract:
(EN) A power supply device is provided. The power supply device includes an AC/DC converter configured to convert an input AC power into a first DC power having a predetermined size, and to output the first DC power, a DC/DC converter configured to convert the first DC power into a second DC power according to an enable signal, and a switch including a soft switch connected to the first DC power at one end, and configured to, in response to the soft switch being turned on, voltage-distribute the first DC power, and to provide the voltage-distributed first DC power to the DC/DC converter as an enable signal.
(FR) L'invention concerne un dispositif d'alimentation électrique. Le dispositif d'alimentation électrique comprend : un convertisseur CA/CC conçu pour convertir un courant d'entrée alternatif en un premier courant continu d'une taille prédéterminée et pour délivrer le premier courant continu ; un convertisseur CC/CC conçu pour convertir le premier courant continu en un second courant continu en fonction d'un signal de mise sous tension ; et un commutateur comprenant un commutateur logiciel connecté au premier courant continu au niveau d'une extrémité, et conçu, en réponse à la mise sous tension du commutateur logiciel, pour distribuer en tension le premier courant continu, et pour fournir le premier courant continu distribué en tension au convertisseur CC/CC en tant que signal de mise sous tension.
