Beschreibung
Zusammenfassung:	The invention concerns a DC-DC conversion device (1) for a charger of a battery (26) of electrical accumulators connected to an electrical grid, capable of operating in a bidirectional manner, comprising at least one resonant full-bridge LLC converter (20), comprising: - a rectifier (24) rectifying the signal amplified by the transformer (23), said rectifier (24) being formed by a full bridge of four parallel structures (240, 240', 240", 240"'), each formed of a transistor (301), a diode (302) and a capacitor (303) mounted in parallel; characterised in that each parallel structure (240, 240', 240", 240"') of the rectifier (24) comprises a device (40) for cancelling the effect of the capacitor (303) of the associated parallel structure (240, 240', 240", 240"') when the DC-DC conversion device (1) operates in indirect mode.
