Electrical-power-supplying device for a wall plug provided with a connector and wall plug provided with a connector and comprising such an electrical-power-supplying device

An electrical-power-supplying device for a wall plug provided with an electrical connector, wherein the electrical-power-supplying device comprises:

• a rectifier, designed to be powered by a source of AC electrical voltage;
• a first DC-DC power converter, comprising:
• an input connected to the output of the rectifier;
• a first output and a second output, the average electrical power delivered on the second output being less than the average electrical power delivered on the first output;
• a second DC-DC power converter, the input of the second power converter being connected to the second output of the first power converter;
• a first filtering capacitor connected to the input of the first power converter, a second filtering capacitor connected to the first output, a third filtering capacitor connected to the second output;
• and wherein the first output of the first power converter and the output of the second power converter are connected in series in order to form an output of the electrical-power-supplying device able to deliver a DC power supply voltage, the electrical-power-supplying device comprising at least a fourth filtering capacitor connected either to the output of the second converter or to the output of the electrical-power-supplying device.
