POWER SUPPLY DEVICE FOR WALL PLUG PROVIDED WITH CONNECTOR, AND WALL PLUG PROVIDED WITH CONNECTOR AND HAVING POWER SUPPLY DEVICE

摘要

A power supply device (10) for a wall plug comprises: a first DC-DC power converter (24) including a first output (28) and a second output; a second DC-DC power converter (50) of which an input is connected to the second output of the first DC-DC power converter; a first capacitor (Cin) connected to the input of the first converter; a second capacitor (Cmain) connected to the first output of the first converter; and a third capacitor connected to the second output of the first converter. The first output of the first converter and a second output (58) of the second converter are connected in series to form an output (60) of the power supply device capable of transferring a DC voltage. The power supply device further comprises at least one fourth capacitor (Csmall, Cout) which is connected to an output of the second converter or to an output of the power supply device.;COPYRIGHT KIPO 2019
