主权项

1. A switched-mode electrical power supply device for regulating a DC input voltage provided between two input terminals of the device by an electrical network, the 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 conversion module in case of outage of the DC input voltage, a management module to manage the charging and discharging of the store module,an electrical transformer, and wherein:
a primary circuit connected between the input terminals comprises a primary winding of the transformer connected in series with a first switching module controlled by the management module, and a closed secondary circuit comprises a secondary winding connected in series with the energy store module and a second switching module controlled by the management module.
