Claim:
1. A switched-mode electrical power supply device for regulating a DC input voltage provided between two input terminals of the switched-mode electrical power supply device by an electrical network, the switched-mode electrical power supply device comprising: at least one conversion module to convert the DC input voltage into a regulated DC voltage, an energy store module to store electrical energy to yield to the at least one conversion module in case of outage of the DC input voltage, a disconnection module for disconnecting the switched-mode electrical power supply device from the electrical network in case of outage of the DC input voltage, a management module distinct from the disconnection module, wherein the management module is directly connected to first and second switching modules and configured to manage charging and discharging of the energy store module by controlling the first and second switching modules, and an electrical transformer, and wherein: a primary circuit connected between the two input terminals comprises a primary winding of the electrical transformer connected in series with the first switching module controlled by the management module, a closed secondary circuit comprises a secondary winding of the electrical transformer connected in series with the energy store module and the second switching module controlled by the management module, and the closed secondary circuit is closed because an input end of the closed secondary circuit and an output end of the closed secondary circuit are directly coupled to a common electrical node, and wherein the input end is electrically coupled to the secondary winding of the electrical transformer and the output end is electrically coupled to the energy store module.
