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

摘要

An electrical-power-supplying device for a wall plug includes a first DC-DC power converter including a first output and a second output; a second DC-DC power converter the input of which is connected to the second output; and a first capacitor connected to the input of the first converter, a second capacitor connected to the first output and a third capacitor connected to the second output. The first output of the first converter and the output of the second converter are connected in series to form an output of the power-supplying device able to deliver a DC voltage, the power-supplying device including at least one fourth capacitor that is connected to the output of the second converter or to the output of the power-supplying device.
