ELECTRICAL POWER SUPPLY DEVICE FOR A WALL SOCKET WITH A CONNECTOR AND A WALL SOCKET WITH A CONNECTOR AND INCLUDING SUCH A POWER SUPPLY DEVICE

摘要

This power supply device (10) for a wall outlet comprises: - a first DC-DC power converter (24), comprising a first output (28) and a second output (30); - a second DC-DC power converter (50), the input of which is connected to the second output; - a first capacitor (Cin) connected to the input of the first converter, a second capacitor (Cmain) connected to the first output, a third capacitor (Cfilter) connected to the second output. The first output of the first converter and the output (58) of the second converter are connected in series to form an output (60) of the power supply device capable of delivering a direct voltage, the power supply device comprising at least a fourth capacitor ( Csmall, Cout) connected to the output of the second converter or to the output of the power supply device.
