DEVICE FOR SUPPLYING POWER FROM AN AC VOLTAGE

The present description concerns a device for delivering a voltage from an AC voltage, comprising a capacitive element (120), two switches (132H, 132L) in a half-bridge between terminals of the capacitive element (120); terminals (102, 104) of application of the AC voltage; a transformer (160), comp...

Zusammenfassung:	The present description concerns a device for delivering a voltage from an AC voltage, comprising a capacitive element (120), two switches (132H, 132L) in a half-bridge between terminals of the capacitive element (120); terminals (102, 104) of application of the AC voltage; a transformer (160), comprising a first winding (162) coupling to a junction node (136) between the switches (132H, 132L) one of the terminals (104) of application of the AC voltage; and one or a plurality of circuits (170, 180, 140), configured to switch the switches (132H, 132L) and receive an AC current (I164) flowing through a second winding (164) of the transformer (160) and regulate the voltage delivered by the device by acting on a frequency of said AC current and/or on a phase shift of said AC current with respect to its reception.
