Abstract: A connection device for connecting a piece of master electronic equipment to a piece of peripheral electronic equipment, each being provided with a respective external connection port of a first type, the device comprising a master connection unit and a peripheral connection unit, each of which is provided with an external connection port of the first type for connecting to the corresponding piece of equipment, and which are connected to each other via electrical isolation using a link of a second type, namely of the Ethernet type, having a transmit line and a receive line, each unit including a first type/Ethernet interface connected to said lines and a power supply module mounted in common mode between the transmit and receive lines in order to transmit or receive AC over the link. A docking station for peripheral equipment including such a device.

Abstract: An AC/DC converter comprising an input rectifier circuit connected in series with a primary winding (5) of an isolating transformer (6) and to a chopper switch (T1) driven by a control circuit (10) using pulse width modulation on the basis of a signal representative of a primary current, the isolating transformer having a first secondary winding (7) that is wound in the same direction as the primary winding and that is connected to an output line (8) of the converter via a diode (D4) and a filter coil (L1), and a second secondary winding (9) that is wound in the opposite direction to the primary winding and that is connected directly to the output line via a diode (D2), the output line being connected to an output capacitor (Cout).
