Abstract: The invention relates to a charging device including a reversible AC/DC converter enabling power to be supplied to two outlets that have different voltages. Said charging device is particularly suitable for use as an on-board electric motor vehicle device. The device enables power to be supplied to both a traction battery, at a relatively high voltage, and apparatuses from the very low-voltage grid. Said device has a small overall size and low weight. The invention rests on a DC/DC converter (in the AC/DC converter) having multiple reversible outlets that includes a single transformer.

Abstract: The extruded section forms a tunnel that is substantially rectangular and is provided with fins on at least one side of the rectangle. The fins allow air to flow outside the housing by natural convection in the extrusion direction. A side without fins serves as a base for fastening the housing and as a support for power electronic components of the power electronic device. The fins are machined transversely to the extrusion direction to form notches in the fins. The notches being aligned in succession to allow air to flow outside the housing by natural convection in the optimum direction.
