Claim 0:
1. A device for delivering a DC voltage between two output terminals from an AC voltage applied to first and second input terminals, comprising:
a first capacitive element;
two first switches in a half-bridge between terminals of the first capacitive element;
two second switches electrically coupled in series between the terminals of the first capacitive element;
a transformer, comprising a first winding placed between a junction node between the first switches and the first input terminals, the second input terminals being coupled to a junction node between the second switches;
a full wave rectifying circuit delivering the DC voltage, comprising:
two second capacitive elements electrically coupled in series between the two output terminals; and
two third switches, each placed between one of the output terminals and a second winding of the transformer;

a circuit configured to switch the first switches at a frequency and to control the second switches; and
a circuit configured to control the DC voltage delivered by the device, by acting on said frequency and/or on a delay between a time when an AC current flowing through the second winding changes direction and a next time of switching of the third switches.
